I am having the exact same problem. It only seems to affect certain SNES roms, and some worse than others. I also tried switching to pisnes but something was wrong with the input configuration since pressing specific buttons gave the wrong action. I couldn’t figure out how to fix that so I am back to the default emulator.
I never did figure out how to get pisnes to work, but think I got the dark picture problem fixed in the default emulator. I disabled video shaders and enabled smoothing in the retroarch config in the all folder and in each emulator config file. For whatever reason, that seems to have solved my dark image problem. Hopefully this helps, locomat.
You should give a try to piSNES. Great compatibility and works like a charm. At least the behavior you described never occured with this emulator. I believe you just have to comment out the proper line in the es_systems.cfg file.
Yes, I did that already. I got pisnes running, but the problem is that it appears that pisnes doesn’t pay any attention to the retroarch.cfg file and the controls don’t match my snes controller. Then I tried re-installing pisnes from source to actually get a config file and after that it wouldn’t run.
how can a noob like me launch piSnes? and is there a way to make it the default emulator in emulationstation over pocketsnes? i don’t have any darkness issues, but there does seem to be some stuttering in a good portion of roms (kirby’s dreamland 3 and super metroid). if pisnes offers improvement i’d like to try it. could someone please help?
Just an update for the original poster; I had the same problem with the backgrounds being too dark. Apparently it is only the default video shader in retroarch that makes this happen. Change the shader to something else and it should solve your problem. I prefer the shader hq2x2. I noticed that leaving video smoothing turned off resulted in better performance.
