XMG FUSION 15 - FREQUENTLY ASKED QUESTIONS (FAQ)

This FAQ represents Q&A's over the last few days here. Fellow redditor u/iterateandgit was so kind to help me putting this document together. Big shout out to him please! The FAQ will be further extended over the coming days and weeks. Please keep the questions coming!

Sales, Shipping, Warranty


Q: Are you going to sell this on Amazon in the EU?
A: We are working on getting the product up and running on Amazon. But our own BTO shop at www.bestware.com will always be our primary sales channel and will be the only one where you can customize and configure memory, storage, OS, extend your warranty and pick other options.

Q: Do you offer student discounts or other sales compaigns like black friday?
A: In general, we don't offer student discounts. Sales campaigns are planned just in time, depending on stock level and cannot be announced early. If you want to keep up to date about sales campaigns, please subscribe to our newsletter.

Q: Do you ship to the UK? Can I pay in GBP?
A: We ship to the UK - the pricing will be in EUR, so your bank will do the conversion. Warranty services will be available from UK, shipping to Germany. Currently, in the single markets, these resturn shipments are free for the end-user. In the worst case there might be additional customs fees for shipping.

Q: What warranty options do you offer?
A: All our laptops come with 2 year warranty. Warranty repairs in the first 6 months are promised to be done within 48 hours (+shipping). Both the "instant repair" service and the warranty itself can be extended to up to 3 years.

Q: Do you sell outside of Europe?
A: We are able to ship anywhere, but warranty for customers outside the region would always involve additional customs cost and paperwork for sending the laptop back to Germany in the rare event of an RMA. There is currently no agreement to let other Local OEMs (like Eluktronics in the US) carry the warranty for XMG customers and vice-versa. Some parts are customized (in our case the LCD lid and the keyboard) and it won't be easy to agree on how to share handling fees etc. - so I wouldn't expect a global warranty anytime soon.


Hardware, Specs, Thermals


Q: What is the difference between XMG FUSION 15 and other laptops based on Intel's reference design?
A: The hardware of the barebone will be identical. Other Local OEMs might use different parts for RAM and SSDs. Our branding and service/warranty options might be different. We apply our own set of performance profiles in the Control Center. This will rebalance the differentiation between Silent, Balanced and Enthusiast modes.

Q: What is the TGP of the NVIDIA RTX 2070 Max-Q?
A: Officially, it is 80W in Balanced profile and 90W in Enthusiast profile. You can toggle between these modes in real-time with a dedicated mode switch button. Inofficially, the TGP can go up to 115W in Enthusiast profile thanks to the Overboost mechanic, working in the background. However, those 115W may only be sustained until the system has reached thermal saturation, i.e. when the GPU is approaching the GPU Temperature Target of 75°C.

Q: Can I upgrade the storage and memory after I buy?
A: On storage: The laptop has two m.2 PCI-Express SSD slots. This will give you currently up to 4 TB of SSD storage. There is no 2.5" HDD slot available. Instead, the battery is enlarged to 93.48Wh. You can see pictures of the interior layouts here, here and here.
On memory: the laptop has two SO-DIMM DDR4 memory sockets. You can chose during BTO configuration, if you want to occupy both of them when you order the product. We recommend running the laptop in Dual Channel for high-performance usage.

Q: How easy is to upgrade and repair this laptop?
A: Here are the key facts:
We would give this a solid 8 out of 10 which is pretty high for such a thin&light design. The 2 remaining points are substracted for BGA CPU and GPU, which is unfortunately unavoidable in such a thin design.

Q: Does it support Windows Hello?
A: A Fingerprint-Reader is not available, but the HD webcam comes with Infrared and supports Windows Hello.

Q: Can I get a smaller, lighter charger for this laptop?
A: XMG FUSION 15 requires a 230W power adaptor to provide full performance. If you max out CPU and GPU with furmark and prime, the 230W adapter will be fully utilized.
There are currently two compatible 230W adapters. They have different dimensions but similar weight. Please refer to this comparison table:
XMG FUSION 15 Power Supply Comparsion Table (Google Drive)
Includes shop links. Will be updated with precise weight numbers in the next few days. I also included 120W, 150W and 180W in this table. They all share the same plug (5.5/2.5,, diameter, 12.5mm length). But 120W and 150W are only rated for 19V but the laptop expect 19.5V. Usually this will be compensated by tolerance but we haven't tested how a system would behave under long-term usage with such an adaptor.
In theory, 120W to 180W are enough for charing the laptop and for browsing/web/media. Even a full CPU stress test could easily be handled. But as soon as you use CPU and GPU together, you'll run into the bottleneck and your performance will be reduced.
Comparison pictures:
These 5 pictures show only the relevant 230W chargers.
Again, the weight is about the same.

Q: Is it possible to boot and run the laptop while the lid is kept closed?
A: Closing the lid under load is not recommended because it will limit the airflow and have a bad effect on keyboard and screen. The laptop likes to take air in from the keycaps. With lid closed, the performance might be limited due to reaching temp targets earlier.

Q: Can I get the laptop without the XMG logo? I will be using it in public presentations and I would not like any brand names visible.
A: We cannot ship without XMG logo, but you can use a dbrand skins to cover our logo. We have not yet decided if we want to invest into integrating XMG FUSION 15 into the dbrand shop. But you can already buy 100% compatible skins by using the page of the Eluktronics MAG-15 at dbrand. The chassis dimensions are exactly the same. Please be aware: you have to manually select the option "No Logo Cutout" if you want to buy these skins for your XMG FUSION 15. According to dbrand, there will be most likely no import fees when ordering from the EU as long as the order is below 100€. Check this thread for details.

Q: Will you offer thermal paste upgrades like Thermal Grizzly Kryonaut or Liquid Metal?
A: Our ODMs are using silicon-based, high-performance thermal compund from international manufacturers like Shin-Etsu (Japan) and M.G. (USA). Intel is using MG-860 in this reference design.
These products are used in the industrial sector, so they have no publicly known brand name. Nevertheless, their high thermal conductivity and guaranteed durability provide optimal and long-lasting cooling of your high-performance laptop. The thermal compounds are applied and sealed automatically by the vendor of the thermal components. They are applied in a highly controlled, standardized manner and provide the best balance of thermal performance, production tolerance and product lifetime.
We are considering offering an upgrade to Thermal Grizzly Kryonaut due to popular demand. Will keep you posted on that.

Q: Could you please provide an estimate for how much regular usage (~10 browser tabs + some IDE) battery backup would this have? Will there be any way to trade-off battery backup with performance?
A: Battery life vs. peak performance can be traded off by using the "Silent" performance profile. You can switch between profiles using a dedicated button on the machine. Your scenario (10 tabs + some IDE) sounds like mostly reading and writing. I would estimate to get at least 7 hours of solid battery life in such a scenario, maybe more. We have achieved 8 hours in 1080p Youtube streaming on WiFi with 50% screen brightness. Adblock and NoScript helps to keep your idle browser tabs in check.


I/O Ports, Peripherals


Q: Why are there not more USB-A 3.1 Gen2 or even USB 3.2 Gen2x2 ports?
A: USB-A 3.1 Gen1 is basically the same as USB 3.0. There aren't a lot of USB-A devices that support more than USB 3.0 speed. Faster devices typically use USB-C connectors and can be used on Thunderbolt 3, which is down-compatible to USB-C 3.1 Gen2. One of the USB-A ports actually supports Gen2 speed.
For the following remarks, please keep in mind that I am not an Intel rep, so everything is based on our own experience.
The mainboard design and the I/O port decisions have been made by Intel. Feedback and requests from LOEM customers have been taken into consideration. We would assume that USB 3.2. Gen2x2 (20 Gbit/s) was not considered to be important enough to safe space for 3rd party IC (integrated circuits) on the motherboard. Right now, all the USB ports and Thunderbolts are supplied by Intel's own IC, so they have full control over the hardware, firmware and driver stack and over power saving and performance control. The more IC you add, the higher your Idle power consumption will be, plus adding potential compatibility or speed issues as it often happens with 1st generation 3rd party USB implementations. I very well remember from my own experience the support stories during the first years of USB 3.0, before it was supported in the Intel chipset. On the one hand, Intel is aiming high in terms of performance and convenience, on the other hand: support and reliability still seem to be Intel's goal #1. Thus they seem to play it safe where they deem it to be reasonable.
Intel is gearing up for USB 4.0 and next-gen Thunderbolt. USB 3.2 2x2 is probably treated as little more than a roadmap accident. Peripheral vendors might see it the same way.

Q: Do you support charging over USB-C/Thunderbolt? Does it support docking stations?
A: The Thunderbolt 3 port in Intel's reference design does not support charging. As you probably know, the 100W limit would not be enough to power the whole system and it would make the mainboard more complex to combine two different ways of charging. Intel consciously opted against it and will probably do so again on future high-end gaming/studio models.
The USB-C/Thunderbolt port supports Dual-Link DisplayPort signals, directly connected to the NVIDIA Graphics. This makes proper docking station usage very convenient. The user still needs to connect the external power adaptor. Both ports (Thunderbolt and DC-in) are in the back of the laptop, making the whole setup appear very neat on the desk.

Q: How many PCIe lanes does the Thunderbolt 3 provide? Are they connected to CPU or Chipset?
A: XMG FUSION 15 supports Thunderbolt 3 with 4 lanes of PCIe 3.0. The lanes come from the chipset because all of the CPU lanes (x16) are fully occupied by the dedicated NVIDIA graphics. We are not aware of any side-effects of running Thunderbolt from the chipset. It is common practice for high-end laptops with high-end graphics. The Thunderbolt solution is of course fully validated and certified by Intel's Thunderbolt labs.

Q: Does it have a standby USB to power USB devices without turning on the laptop?
A: Yes, the USB-A port on the left side supports this feature.


LCD Screen


Q: Which LCD panel is being used? Are there plans for 1440p or 4K panels in the laptop? How about PWM flickering?
A: The panel is BOE NV156FHM-N4G. It is currently not known if the panel will change in later batches. This depends on logistics and stock. At any rate, the panel key specs will remain the same. There are currently no plans to offer resolutions above FHD in the current generation of this laptop.
There are very wide ranges on reports of Backlight Brightness PWM control on this panel in different laptops. Ranging from 200Hz to 1000Hz to no PWM at all - all on the same panel model number. Intel informs us that there are many factors (e.g. freq., display driver, BIOS settings implementation, type of dimmers & compatibility with the driver etc.) that impacts the quality of panel dimming performance. To Intel's knowledge, no kind of flickering has been reported during the validation process. Furthermore, first hands-on data from Notebookcheck indicates that no PWM occurs on this panel. With a DSLR test (multiple burst shots at 1/4000s exposure time) I can confirm that there is not a single frame of brightness dipping or black screen, not even at minimum LCD brightness. Hence, we can confirm: BOE NV156FHM-N4G in XMG FUSION 15 (with Intel) does not use PWM for backlight control.

Q: Some BTO shops, for an additional fee, manually pick out display panels with the least back-light bleed. Do you offer that? Even better, do you do that without the extra fee?
A: Intel has validated this design to avoid backlight bleed as much as possible. Currently no plans to do further binning. All dozens of MP samples we have seen so far have been exceptionally good.

Q: I'm coming from a 13" MacBook with Retina display. How am I going to fare with this 15.6" FHD screen in content creation?
A: If you got used to editing high-res visual content (photography, artwork) on your 13inch retina, things will change. On the one hand, your canvas will be larger and more convenient and ergonomic to work with. On the other hand, you will find yourself zooming in more often in order to make out fine-detail. Assuming that you have sharp 20:20 vision.
As it is, the screen resolution and specs are not planned to change within the lifetime of this product. The first realistic time-window for a refresh would be whenever Intel is releasing the next "H" series CPU generation. But even then, an upgrade on resolution will not be guaranteed.
Comparison:
Laptop Resolution Pixel per inch dot pitch
13.3" MacBook Pro Retina (late 2013) 2560x1600 226.98 PPI 0.1119mm
15.6" XMG FUSION 15 (late 2019) 1920x1080 141.21 PPI 0.1799mm
To compare: 141.21 is ~62% from 226.98. This represents the the metric difference in pixel density and peak sharpness between these two models.
If you know the diagonal size and resolution of your screen, you can make this comparison yourself with the DPI/PPI calculator.


Keyboard, Backlight, Switches, Layout


Q: What can you tell us about the mechanical keyboard of XMG FUSION 15?
A: The keyboard has already been reviewed in our XMG NEO series as being more crisp than typical membrane keyboards. Most reviewers attested it a very good score, both for gaming and for writing long texts.
The keyboard backlight can be configured per-key. Default mode is all white.
Keyboard Switch Specs:
Having no frame around the keycaps actually helps the thermals. The fans can pull in additional air from the top. This improves airflow and helps to keep the keyboard temperature at low levels during gaming. It also prevents long-term RMA issues on the keyboard. This specific keyboard switch is already in its 3rd generation and very mature by now.

Q: Is it possible to dampen the mechanical keyboard with o-rings?
A: The switch design does not lend itself to further dampening. The switch mechanic is too complex and has more moving parts than cherry. The 2mm travel distance also plays a role in not allowing more dampening.
For reference, please use this video (Youtube). We compared XMG NEO with another membrane-type keyboard. XMG NEO and FUSION share the same keyboard mechanics with the silent tactile switch and the same sound profile.

Q: Do you have LED keyboard backlight on the secondary key function, like Fn key icons?
A: Please have a look at this picture.
Btw, my working sample has blank keycaps. I took the 3 printed keycaps (F8, F9, F10) from a different sample just to demonstrate the Fn lighting for this picture.
Facts:
In my assesment, the Fn function symbols are clearly visible from the backlight in a dark room. A user should have no difficulty to recognize the icon and reach its function.

Q: Which keyboard layouts do you offer in the EU?
A: The following layouts are available, in alphabetic order: Belgium, Czech, Danish, Dvorak German, Dvorak US, Estonia, French, German, Greek, Italian, Norwegian, Polish for Typists, Portuguese, Russia Latin, Slovakish, Spanish, Swedish / Finnish, Swiss, Turkish, UK, US International (ISO)All these layouts are based on the ISO matrix. See differences between ANSI vs. ISO here.


Operating System


Q: Do you support Linux and dual-boot on XMG FUSION 15?
A: We are in discussion to sell XMG FUSION 15 over Tuxedo with official Linux support. It might take 1 or 2 months to get this running.

Q: Which LAN, Audio and WiFi card vendors will be used? Asking for a friend.
A: From our HWiNFO64 report. (Google Drive link)
LAN: RealTek Semiconductor RTL8168/8111 [PCI\VEN_10EC&DEV_8168&SUBSYS_20868086&REV_15]Audio: Intel(R) Smart Sound Technology (Intel(R) SST) Audio Controller [PCI\VEN_8086&DEV_A348&SUBSYS_20868086&REV_10]WiFi: Intel(R) Wi-Fi 6 AX200 [PCI\VEN_8086&DEV_2723&SUBSYS_00848086&REV_1A], can be replaced.
For more information, please check the linked report file.


Other questions


Q: What would you say are the advantages and differences with other laptops due to the fact the laptop was designed in collaboration with Intel?
A: Disclaimer: I am \not* an Intel rep. The following remarks are based on my personal experience and opinion.*
Advantages:
  1. Very strict quality control on all levels. I can't quote numbers due to NDA, but Intel NUC has extremely low RMA rates, compared to average PC mainboards and systems. Intel is driven by strict internal regulation that strifes for perfection - this applies to the whole chassis, assembly and firmware, not only the mainboard. There are also certain regulations in place, for example in terms of electro-magnetic regulation and skin temperatures. The rating label is littered with regulatory seals from every region of the world, making this laptop especially safe to use.
  2. Access to high-quality material: we have not seen any Gaming Laptops based on Magnesium alloy yet, especially not in the ODM/LOEM ecosystem. The battery cells are also much more dense than what we usually see. Intel has the buying power and the vision to not settle for mediocre parts.
  3. Down-to-earth design: Intel has made this reference design for the ODM/LOEM eco-system. The design does not try to follow any specific corporate identity, thus it does not have any unneccessary "bling bling" like all the others have. Even the Razer Blade with it's sleek shape is quite obnoxious (iny my oppinion) with it's big backlit green snake logo. With XMG FUSION however, we can continue our typical style of "Undercover Gaming".
  4. Security: you can expect stellar support in terms of BIOS and Firmware (TPM, Management Engine) updates whenever any security issues are found. This might also apply to global brands, but ODM/LOEM systems have not always been so quick to react. This is due to the huge fragmentation/customizations in ODM/LOEM systems. Intel however does now allow any fragmentation: every LOEM partner is getting the same firmware. There are many hooks for configurations in this firmware, but the source code / binaries are always the same. This makes support much easier down the line.
Disadvantages:
  1. I can't name many, of course. But I would say the strict validation also makes the partnership less flexible from a product management perspective. There is no plan currently to phase-in any 4K or 300Hz screen (FHD/144Hz ought to be enough for everyone this year) or any Core i9 in this system. Other ODMs might be more open for costly modifications based on low quantities. Intel however has streamlined their production and logistics in a way that gives us (the LOEM) very short lead times and competitive pricing, but will not allow any short-notice upgrades or customizations.

Q: Will there be a 17 inch version?
A: We can neither confirm nor deny plans for a 17 inch version at this point.

Waltonchain All-In-One Thread

This All-In-One Thread is still undergoing correction. Feel free to post below and let me know if something needs to be corrected.
What is Waltonchain?
Waltonchain is the only truly decentralized platform combining blockchain with the Internet of Things (IoT) via RFID technology. Their blockchain is implemented in the foundational layer, through their unique, patented RFID chips, which are able to read and write directly to the blockchain, creating a genuine, trustworthy, and traceable business ecosystem, with complete data sharing and absolute information transparency.

Frequently Asked Questions
Q: When will Token Swap Happen? Did Mainnet Release?
Waltonchain has launched mainnet, token swap has not happened yet in progress. Token swap from Ethereum to Watlon's own chain is trending to occur complete in Q2 2019 Q4 2019-?. To prepare for swap you can hold your tokens on any of the listed exchanges. For additional information as it becomes available one should follow Walton on twitter.
Q:What's the Total Supply of Waltoncoin (WTC)?
The Total Supply is 100 million coins with no further issuance in any case. The Max Supply is currently 70 million coins, with the remaining 30 million left to be mined over the course of many years. Currently, the Circulating Supply is around 25 million.
Q:I hear Walton is moving to its own blockchain?
Main net has just been launched. Stay tuned for details about the token swap and transition to the new chain!
Q:How do I convert my ERC20 WTC tokens to the real thing?
You can either leave your coins on the exchange, and they will take care of the switch for you, or you can leave them in your MEW wallet, and the team will provide details on how the tokens will be swapped over. Just sit tight! Details are coming.
Q: How do I move my WTC to MEW (or the new Walton Wallet)?
For MEW:
I. Send your WTC to your wallet address.
II. Add a custom token using the information below:
Address: 0xb7cb1c96db6b22b0d3d9536e0108d062bd488f74
Name: WTC
Decimals: 18
For Walton Wallet:
Do not send ANY coins to this wallet yet. Wait for instructions from the team. Once everything is safe, you will be able to just create a wallet on the Walton Wallet and send your coins to the public address generated.
Q:What if I want to keep them on my Ledger Nano?
You can do that, and the team will still snapshot your wallet and copy it along with your coins; however, the the Ledger may not support WTC currently. Don't fret. Your coins are 100% safe. What that means is, if there is no Ledger support, the only way to transfer your coins out of the wallet will be to expose your Ledger's private key. I don't recommend doing this, as it will make the ledger no more secure than a paper wallet (still very secure, but a waste of money now).
So basically, your coins are safe. You can still mine to the address. You just won't be able to move them until Ledger support comes. But if you really need access to the coins, you can break out the Ledger's private key on MEW and log into your wallet.
Ledger support will come, we just don't know exactly when. Walton is also making their own Walton hardware wallets. I'll update this with more information as it comes.
Q:My GMN is on MEW. Will I ever be able to secure GMN in a hardware wallet?
As you know, moving your GMN will void your Guardian status because it is attached to the wallet containing at least 5000 WTC; however, the team has stated that they are working on a solution for this and have reassured us that our coins will be safe. We will have to wait for more information regarding whether the transferring of a GMN to a new address will be possible in the future.
Q:What is the utility of WTC? What gives the coin value?
In the WaltonChain Ecosystem WTC will have multiple functions:
More in depth coverage of each point here
Q: Is Waltonchain a platform?
Yes. Waltonchain is a smart contract platform that will have ICOs and dApps.
Q: But I thought Walton just tracked clothing in the supply chain. What else can it do?
Walton is capable of implementation in smart cities, smart waste management systems, and things of that nature. That's certainly beyond supply chain. Walton isn't so much a "supply chain" coin as it is a Big Data coin. The RFIDs are used to gather data, which is very useful in supply chain management. But it can also be used to combine with smart devices and make an Internet of things network.
Q: Why does this need a blockchain?
"It is difficult for the Internet of things under the current central structure to accomplish real autonomous cooperation and effective transactions, because the relevant parties of such cooperation and transactions often belong to different stakeholders with complex and uncertain trust relationships. Therefore, the collaboration and transactions of the current Internet of Things devices can only be carried out under the same trust domain. That is to say, the devices to collaborate and trade must be provided or verified by the same Internet of Things service provider, which significantly reduces the true commercial value of the Internet of Things applications." (Page 2 of the Whitepaper)
To expand, counterfeiting is an obvious answer to this question. There needs to be a way to truly authenticate an item. Blockchain is that answer.
Walton's blockchain also removes data silos. Companies won't have to manage any database anymore. Everything is handled by Walton. Walton uses child chains which are separate from the parent chain. Companies can keep proprietary information secret and private on their child chain, and only broadcast necessary information to the parent chain for public viewing. Blockchains make the sharing of info between companies easy and fast, too. And then obviously, blockchains have perfect transparency and are immutable.
Smart contracts are also extremely useful. In the supply chain industry, after perfectly counting and storing inventory, things can be auto-ordered and paid for simultaneously with wtc, just as an example. Your mind can come up with a whole host of other ideas related to automation.
Furthermore, decentralized, transparent, and immutable data for things like smart waste management systems, which Walton has designed, and air-pollution monitoring systems in smart cities would benefit greatly from the blockchain, for reasons explained in the first point from the whitepaper.
You could also imagine on the customer end that wanting to know where all their goods come from is important. This is in line with counterfeiting, but also with things more benign. Imagine wanting to return an item to a store, but can't remember which grocery store it was from. Lots of simple improvements like that are all use cases for blockchain.
Q: I heard Waltonchain has patented technology. What are the patents?
The Walton team has filed filed for 13 patents, 7 of which have been approved so far. The patents cover many inventions in chip design, but the main one of interest is the Transaction ID-reading RFID chip with memory storage. This allows the blockchain to be implemented in the Foundational layer through the RFIDs themselves. The chips can generate their own random ID hash within a secure Key Generation Center within the chip, and the hash along with the data are uploaded simultaneously to the blockchain via their RFID reader. This makes WaltonChain fully decentralized and secure.
Q:What are the advantages of the RFID IC tag chip designed in this project?
Existing RFID chip industry cannot meet the development of Internet of Things applications, especially applications for the Value Internet of Things:
The project’s IC design has the following significant advantages:
Q:How much do the chips cost?
Waltonchain in a nutshell with COO Monitor Chan:"We develop and produce hardware such as chips ourselves. This really differentiates us from other companies at the moment. Basically, Silitec, our technical support company, was founded in 2015 and is specialized in manufacturing chips. They already have a R&D team of around 20+ people, so in that way we are not 'increasing' cost. Next important detail is that Waltonchain’s blockchain technology is written into our chips. This means that unlike traditional RFID chips that have their own specific ID and cost around $0.15 to $0.20, the chips we develop will be below 5 cents. With the volume of sales increasing, the overall cost will spread over many units, and the system's cost and ID’s cost will go down consequently, or simply put, economics of scale will do the work."
Q:I need help with mining. What resources are out there?
WaltonchainMining is for this purpose. Community members here have done testing with many different configurations and have provided ample information for anything you need with setting up your cpu/gpu rig.
Q:How many GMNs are left?

MAME 0.215

MAME 0.215

A wild MAME 0.215 appears! Yes, another month has gone by, and it’s time to check out what’s new. On the arcade side, Taito’s incredibly rare 4-screen top-down racer Super Dead Heat is now playable! Joining its ranks are other rarities, such as the European release of Capcom‘s 19XX: The War Against Destiny, and a bootleg of Jaleco’s P-47 – The Freedom Fighter using a different sound system. We’ve got three newly supported Game & Watch titles: Lion, Manhole, and Spitball Sparky, as well as the crystal screen version of Super Mario Bros. Two new JAKKS Pacific TV games, Capcom 3-in-1 and Disney Princesses, have also been added.
Other improvements include several more protection microcontrollers dumped and emulated, the NCR Decision Mate V working (now including hard disk controllers), graphics fixes for the 68k-based SNK and Alpha Denshi games, and some graphical updates to the Super A'Can driver.
We’ve updated bgfx, adding preliminary Vulkan support. There are some issues we’re aware of, so if you run into issues, check our GitHub issues page to see if it’s already known, and report it if it isn’t. We’ve also improved support for building and running on Linux systems without X11.
You can get the source and Windows binary packages from the download page.
