Hi
I don't know whether legacy PC emulation belong in this forum, but here goes:
I'm working on a wrapper for the Rendition Verité V2200 (an old video card from the 90s). The Windows side of it is almost done and can run all 13 games though a few need DxWnd or dgVood's DirectDraw component. The DOS part is still being looked at.
I haven't had much too much feedback, especially from AMD GPU users:

- Ability to restrict VRAM by setting MaxVRAM=<nn>(Megabytes). The Golems in VH2.exe correctly change colour when VRAM is restricted to between 4-14 MB. Restricting VRAM will severely affect performance and is not recommended. It is also unsupported in other apps.
- RRosetta's renderer switching (using F1-F3) work correctly but for F3 (Direct3D) to work dgVoodo's directdraw/direct3d files need to be copied to the same folder as RRosetta.exe. OpenGL to RRedline switch to work.
- Screenshot capability in games such as WinDie.exe (save game image) or games which have a console command 'screenshot' should work (except VH2.exe. This application appear to do a copy to clipboard and does not currently work.). Screenshot is correctly downsampled now.
- End credits background textures in F1red.exe should work.
- Bilinear filtering (using shaders) is enforced for paletted textures.
- Memory safety checks removed. Should be as fast as before.
(This release is live on the Windows store as well without the watermark though it costs money)

I'd be really happy for feedback and sorry if this forum isn't the right place for it.
Thanks!
ICR2 HUD issues fixed completely:
Nascar 2/Nascar Racing 1999 Rear view mirror colour fix:
Tomb Raider: Massive Chroma Keying improvments and Health+Oxygen bars
vQuake: Scourge of Armagon works with Dosbox/RReady
(r_surfacelookup must be set to "0", just like for vQuake. This is a bug with the Dosbox/RReady and will be fixed.
vQuake: Malice
r_surfacelookup must be set to "0", just like for vQuake. This is a bug with the Dosbox/RReady and will be fixed.
Dissolution of Eternity doesn't run for some reason. It will be fixed.

[/EDIT]
vQuake: Dissolution of Eternity
r_surfacelookup must be set to "0", just like for vQuake. This is a bug with the Dosbox/RReady and will be fixed.
The quake.rc file contained in the pak file has an incompatibility with Dosbox/RReady. Adding a text file with name quake.rc with the text listed below will fix it for now:
// load the base configuration
exec default.cfg
// load the last saved configuration
exec config.cfg
// run a user script file if present
exec autoexec.cfg
// stuff command line statements
stuffcmds
// start demos if not allready running a server

Setup guide for MDK with RReady (both Alpha and Microsoft Store):
The textual description has details (at the bottom for Quake 2 and Hexen II) on how to set things up. It's very painful to make these videos, takes up a lot of time, but I'll try and post videos for Quake 2 and Hexen II.
You are a machine!
This is a crazy amount of work.
Great job!
I started work on this 3 years ago, so I've had a lot of time.

Here's yet endless split screen video of dosbox-rendition before and after embedding the wrapper. Some games show no change in performance or regress but vQuake sees significant performance improvements.

- Fixes r_surfacelookup "1" not working. The earlier betas should render, but r_surfacelookup "1" and earlier betas are not officially supported, yet. There may be bugs. Note enabling surfacelookup ("1") is slower than disabling it ("0"). This is true for vQuake 2 and vHexen II as well with RReady.
- vQuake 2 chroma keying and texture filtering is now shader based. This should fix pixelated textures in expansion pack "The Reckoning."
- RLauncher remembers the last tab and selected app in each and every tab between restarts.
This will be tested and released to the Store once it's validated.
The embedded code path has been abandoned. Only vQuake saw any improvement and with staging the improvements were minimal. Others regressed or ran the same.
Thanks @mickyat2001

- Fixes random texture corruption with r_surfacelookup 1 (vQuake 1). On weaker CPUs (in modern terms) r_surfacelookup 1 will be faster, just like in Rendition's heyday.
One final Quake engine video, this is the last one:
The effects of v1k_surfacelookup/r_surfacelookup.
vQuake cvars, by popular request (not on this forum):
And no more vQuake vids.
I've tweaked Dosbox-Rendition's register access slightly while trying to get Eurofighter to run and noticed I can get Nascar 1999's framerates stable (Nascar 2 was already stable). Even managed to briefly get ICR2's replays going faster, but it turns out it was a random glitch somewhere.
I can even get it to run (slowly) on Intel UHD620 (2 real+2 virtual threads @ 2.1 GHz). Something it never did before.
EF2000 is still not quite there yet.

Fixes: Nascar 1999 Racing performance boost
MDK : Power up indictator on bottom right has correct background colour
Regressions: ICR2 may have audio pops. This is because of the Nascar fixes. This isn't going on to the store/sourceforge until I fix it. If someone could confirm that they do get audio popping in ICR2 it would be useful, to make sure it's not just my machine.

- Nascar some texture clamping issues fixed
- MDK weapon power up blended background in HUD
The Nascar 1999 optimisations aren't there (they won't be necessary and the performance boost will be there in the next release without this)
and neither are the new vQuake engine edge AA shaders.
Upcoming optimisations for Speedy3D apps in the next release, everything should run at at least 30 fps:
- vQuake no static with Dosbox-Rendition, almost as fast as Dosbox-Staging-Rendition without embedding
- Rebel Moon, no slowdown
- ICR2 full frame with replays and carsets:

MD5: 89bfd9f38babf0e3b90ac3cf841bd882
[rendition]
highperformance = true|false (default:true)
picdma = true|false (default:false)
highperformance allows the new fast mode and picdma makes it threadsafe (but at the expense of performance).
I would recommend testing it with highperfornance = true and picdma = false. If there're any stability issues in ICR2 or Nascar 1999, setting picdma = true to gauge performance would also be useful. (picdma = true is a death sentence for weaker CPUs).
Setting
[sdl]
priority = normal, normal
in dosbox.conf might be necessary for:
[rendition]
highperformance = true
picdma = false

And finally an obligatory vQuake performance improvement video:
https://youtu.be/1AqPS1_1qKs
The reason the now abandoned embedded codepath ran so well (for vQuake and everything else ran the same or slowed down) was because Dosclient was embedded into Dosbox, so the app had focus. It's explained in the video description.

- Initial support for Eur*figher 2000+ in FIFO mode( DMA mode does not currently work reliably)
- Performance increases across the board with two new settings:
[rendition]
Highperformance=true
Picdma=true
And
[sdl]
Priority=normal, normal
(Previous DMA performance can be restored by setting both these to false. Threadsafe=true only has an effect if both these are set to false).
The new high-performance mode is extremely CPU intensive and might not work on older CPUs and might introduce audio static (random occasional pops).
- Compatible custom car sets in ICR2 should be usable on most modern quad core or better systems.
- R*belMoon should sustain a solid 60 fps right throughout.
- R*belMoon chroma keying fixes: particle impact cloud sprites should render fully and not be clipped.
- FIFO mode memory write tweaks to support EF2000+ in FIFO mode.
- Dosbox-Staging-Rendition has a full set of config settings under [rendition]. It also has performance improvements in ICR2. However it may have stability issues with N*scar Racing 1999R and possibly other apps. It does not currently support per-app config files.
- N*scar Racing 1999 improved stability with Dosbox-Rendition.
- Dosbox-Rendition vQ*ake performance parity with Dosbox-Staging-Rendition.
- T*am Apache may have compatibility issues with cutscenes with the October updates to Windows 11/nvidia drivers.

-Windowed mode support (this will allow alternate frame generation through "Lossless Scaling" (Steam, not-supplied) when a custom resolution less than the screen is used. Knocking one pixel off the horizontal resolution (i.e. 1919x1080x60 for 1080p) will work without any scaling artifacts in Lossless Scaling.
- Restores generic VESA support for non-Rendition apps in Dosbox-Rendition, such as setup.exe in TR1, for audio config.
-Adds Rendition 32 bit mode VESA support for CGL demo “21s Century Digital Boy.” The CGL 3D sections do not work currently.
