Yes. @guest.r changed the name from GDV2 to GDV-Advanced a while back.

Just wanted to pop in and give a big thanks for porting this shader to Reshade. CRT Guest Dr Venom has been one of my favorite CRT shaders to date and now I can use it will all kinds of PC games that I wish to.
I can also combine it with 3dfx games, since 3dfx APIs such as nglide and dgvoodoo2 convert the calls to DirectX 11, which I then can combine with Reshade to add desired effects.
One interesting one, here are a couple of screenshots of POD Gold with dgvoodoo2, running with Reshade using CRT Guest Advanced. Menus are at 640x480 internal resolution with gameplay at 800x600.
I plan on testing this out with many different games I have on hand.

I just wanted to leave a big Thanks for this great Shader !!! All Retro systems like PS1, PS1, Dreamcast, Gamecube etc. as well as Arcade etc. look absolut great with this shader when configured properly. I can sell my 31 and 15 khz CRT’s now and play everything on my OLED as it look really CRT’ish now and doesn’t leave much to be desired. Thank you !!!

Hey I need some help using CRT-Guest-Advanced for ReShade with MAME Standalone. First, I made sure integer scaling was on and that I disabled ‘unevenstretch’.
Example: I want to play Marvel vs Capcom. The default resolution is 384x224. I know that it’s not 4:3 but it does get turned to this aspect.
What should I use for these options? My current screen is 1920x1200
Resolution x =
Resolution y =
.fx file definitions
x =
y =
I assumed both X would be 384 and both y would be 224 but I get scaling artifacts (crawling) if I try this and other settings cause blurring.
thanks.

Can you post some screenshots?

Oh, did you mean the integer scale option in MAME and not the one’s in the shader itself? As ReShade can’t get access to that unlike the RA version (hence also why there are parameters for ResolutionX and ResolutionY).
You need to play in your monitors full height of 1200p. For 4:3 width you have to run MAME at 1600x1200, you can try Res-O-Matic for that.

I constantly switch between CRT-royale and dr Venom but the latter wins for lowres for sure. Any chance of porting the “hires” version by ‘guest.r’ to Reshade?

Any idea why the text is messed up? This pic is taken with the default settings in Guest-Dr-Venom. According to PC gaming wiki, the native resolution for Bloodstained is 426x240. I tried changing the Texture_Res_X in the .fx file to match, but it didn’t fix it. I also tried doubling the resolution, and that didn’t fix it either.

Both axes are missing lines, so the res is too small in both directions. Perhaps it uses a different resolution in menus?

1st time here, and necroing this thread, but with the latest Reshade 5 update, i think it would be nice to see this added to shader repo

Hi, I realized that the latest version of the CRT-Guest-Advanced port is not in the first post, can you point me in the direction of the latest version please?
Also, can you give me a quick description of the installation steps for your shaders please?
I’ve used ReShade before but only installed it a few times so I might just need a quick refresher.
I would like to create my own preset for TMNT: Shredder’s Revenge. Haven’t found the native resolution on PC Gaming Wiki.
I’m going to start winging it but any assistance would be greatly appreciated.

That’s the most latest (over a year old) version of GDV-Advanced ReShade port. Just copy and save it as a .fx text file.
(I’ll be able to help you more in the morning as I’m currently preparing to go to sleep.)

Thanks, I got it installed. The next issue is that the resolution looks too low and I can’t seem to increase it from 320 x 240. I tried CRT-Geom and I was able to change the resolution to 720 x 360 and the scanlines look a bit even now.
I’m looking forward to learning how to use ReShade as well as I use can native RetroArch CRT Shaders.
Update: 480 x 270 Seems to work well.
You have to click on the image then click Load Full Resolution, Then zoom in or view Fullscreen.
Update:
I think I’ve got it.

Yes. 270 height seems to be the correct height for this game. The easiest way to figure out the internal resolution of these modern pixel art games is to look at the DIAGONAL lines in the image when using a scanline shader. If they look right/clean, you have found the right resolution.

Is there a tutorial on how to convert a Retroarch shader to Reshade? There are a bunch of old PC games in 4:3 I’d like the option to use ambient glow on them.
Is there a way to stagger the mask to turn the aperture grill mask into a shadow mask like in the libretro version?
