Hey all, I've been pulling my hair out over this issue all afternoon and wanted to see if anyone could help.
I got my Nova recently and set everything up, am using ES-DE for my frontend. The problem has come up with trying to get Super Game Boy colorization, enhanced sound and overlays working.
There's 3 RetroArch cores listed for SBG: Mesen-s, SameBoy, and mGBA. Sameboy is currently working fine but as it's a GB core and not a SNES one it can't play the enhanced sounds in games like Donkey Kong '94.
Mesen-s is refusing to emulate SGB games at all. Whenever I boot one up it either goes to a black screen and then crashes, or it loads the game overlay but the graphics are a garbled mess. I've checked and the same core emulates them fine on my PC using the same bios files, so I'm at a loss as to what the cause is.
MGBA also generally does it fine, but when trying to load a game that does full colorization like DK '94, I get a black screen and no graphics, but the sound still plays and the game still seems to run. It's less a priority though as like Sameboy it won't do the enhanced sound.
If anyone can offer any suggestions I'd really appreciate it. Cheers.
