Okay, I'm about to tear my hair out over this because it's driving me mad. I just installed the latest stable build of gpSP from the OP on my n3DS XL, have the GBA BIOS properly named and placed and every single game I play has this really ugly graphical glitching at the top of the screen that's very distracting and not pleasant to look at, and the one game I tested where it actually went away after a few seconds of play (Kirby: Nightmare in Dreamland) crashed the system after about a minute of play with no glitch. I -know- gpSP is capable of running GBA games flawlessly, because there's literally video proof on youtube from two years ago of someone running multiple games on it, switching back and forth between them, and there's not a graphical glitch in sight. I've messed with any video setting I can find to see if it fixes the issue, but no such luck. I tried mGBA to see if that was better and the sound was god awful, there were no settings or easy way to swap roms without quitting the program and it was just generally unpleasant, so it's back to gpSP, where the sound is basically perfect, games run well (outside of that one crash) and everything seems to be flawless except for that glitching. Has anyone else run into this and figured out how to fix it? Maybe I'd be better off using an older build? If so does anyone know a good one that will run without graphical glitching? Any help at all would be appreciated. I'd really like to get this figured out so I can enjoy my GBA games, haha.
