Some questions about Retroarch, Neogeo emulation and shaders

Sun Mar 16, 2014 5:08 pm

Hi everybody,
it seems that RetroArch on Raspberry Pi now supports shaders. :o

So, before starting compiling, tutorials etc. I'd really like to get an idea, if possible, of what are performances on a (overclocked) rPi running Neogeo games with RetroArch and a crt-like shader, like Phosphor...

Thank you very much... ;)

There's no way to archieve fullspeed NEO GEO emulation on the Raspberry Pi using RetroArch. You'll have to use piMAME4all or piFBA for that, wich don't include multi-pass shaders, but a simple, basic GLSL shader built-in. Feel free to modify the built-in shaders for these emulators.

Hi and thank you for your answer :)
And what about SNES, NES and Genesis emulation on RetroArch with "phosphor" shader enabled? It is possible to reach full speed?

Unfortunately I'm not a developer, nevertheless how much "difficult" would be to modify the basic GLSL shader built in piFBA and piMAME4ALL?

Thank you very much
