Specifically the crt-easymode.glslp (Non halation) shader?
Sure, someone knowledgeable with the BGFX syntax could do it.
Where would one find such a mythical creature? lol
I would think MAME’s forums/IRC/whatever would be a good place to look.
Any particular reason not to go for MAME GLSL? Crt-easymode should work fine…
Only that i’d never heard of it until now
