Shader for DOS games?

RetroArch Additions Shaders
#1

Hi all :slight_smile:

First post here but I have been a silent reader for quite some time.

English is not my primary language so apologies for any mistake.

I am about to go on a DOS RPG and point and click “rampage” (ranging from 1990 to 1995) and I was wondering if anyone could point me toward a CRT shader to simulate the display of early 90’s monitor ?

I see a lot of discussions around arcade monitors and Tv settings to display old consoles but not much relating to DOS (CGA/EGA/VGA display)

I believe that most games of the DOS era were using a resolution of 320*200.

It is possible that the CRT shaders currently available for use with retroarch would do the trick but if anyone could provide guidance that would be great :slight_smile:

Thank you.

For <480p, any of them should work fine, though crt-lottes and crt-royale have some mask parameters to mimic the shadowmask on typical VGA displays. For >=480p, the scanline effects aren’t necessary and you might be better served by GTU with the scanline effect disabled followed by dotmask.cg, which has those same VGA mask options copied out of crt-lottes.

for CGA a composite video shader shoulb be nice (CGA was design to be used with it)

Thank you Hunterk and R4Zi3L for your help :slight_smile: I will try crt-lottes to see how this one goes.
