giving my retropie another look. Trying to figure out this shader business and oof. oooooffff.
So here's the thing, my pi3b uses picodrive via the Libretro extension thingy by default. Looking into it, there's two other emulators available, those being Genesis Plus GX, and the other being DGEN. I'm not sure which I should be using in actuality for just megadrive emulation, or which would give the best appearance because good lord I really want to be able to get something close to CRT quality.
((or finding a crt monitor to use with it and somehow converting mini-hdmi to dsub which it will invariably need))
@renbymon oh what the shit that's COOL. Okay if I ever get the opportunity to get a CRT tv I am SO getting that piece of kit because that would be perfect to retrogame on. Thanks! Doesn't immediately fix the problem on the cheap but this is definitely a "holy shit I kinda need that!" :D <3
@Nine It's on my list of things to get once moving has happened. :>
@Nine Good question. I'm throiwing a random guess and suggestign picodrive because I only remember DGen as an old software.
But for shaders, it'd be mostly Libretro's itself that manages shaders, not the emulator.
@Nine Through filters or shaders, libretro edits itself the result the emulator gives and slaps it on the screen.
@Ronflaix yeah the problem is finding the right shader that doesn't slow the emulation to a crawl cc;; I'm wondering if GenPlusGX is faster and more lightweight than picodrive because picodrive struggles with a lot of the shaders. like... really struggles.
...like... super slow motion garbling struggling.
@Nine Well, the Pi isn't designed to run the CRT shaders like Crt-royale&co, even my GTX850m can slow down a lot due to how expensive they are.
Try with the tailored Pi filters? They're not very accurate bu thtey get the job. Or maybe the custom shaders for the Pu like those listed there : https://github.com/RetroPie/RetroPie-Setup/wiki/Shaders-and-Smoothing#retropie-alternatives
@Nine I hope their driverd also make OpenGL run on the GPU and not the CPU. IT'd alleviate a lot of the charge out of the CPU. While developping my thing, I had to tweak my setup to use Xorg for this driver to gain shader support (while keeping the perf boost)
@Ronflaix Yeah those come preloaded on the retropie installation now, a lot of them are just... too slow though even on a pi3b for some reason :< the crt-* ones are.. okay? but they only seem to add scanlines, curvature distortion, and that's it, which is disappointing
(you know without actually having to work out how to use this on a cRT monitor)
