Pretty good, though varies by game. Best played on N3DS.
typically gpsp is the way to go in terms of gba emulation. it is very game dependent on what runs full speed and what doesn't (more on O3ds), and random crashes have been an issue. If the game is crashing, just use a VC inject or install a .cia of the gba game from the iso site. On N3ds, almost everything is at full speed.
its more 'game-dependent'. never had a crash with pokemon games like emerald (the main ones)
what for? gpsp runs much faster than it, but it crashes. There is the homebrew mgba, which you should be able to use, too.
I was told the latest mgab is better than gpsp in terms of performance, is that true?
depends on console and game. Some games run better on one than the other, and gpsp has been known to crash on certain games. It might be a N3ds thing, but last time I tried, mgba still wouldn't come close to the framerate gpsp would give me for pokemon emerald. (on my O3ds)
Thank you very much, I'm using O3ds for emualtions, so I will install gpsp then.
That would be alot of icons, since you just have to copy the 'retroarch' folder, and then install the .cia files for the cores you want to use. those icons are the ones which appear on the home screen.
ok. VC injects/pre-compiled CIAs or gba games would be your other option if you are having issues with gpsp crashing
boop. https://buildbot.libretro.com/stable/1.4.1/nintendo/3ds/RetroArch_cia.7z install all of these cias. Or just the emulators you're interested in. On o3ds, snes, gba, and ps1 wont work pretty much at all though.
