PocketSNES standalone build

[Rebusmind]

Have you seen this thread, where I posted a longer description how to get the standalone emulators to work?

All emulators run awfully, are there any better gba and snes emulators?

I recently built a gameshell, but I’m very disappointed. The games look blurry and washed out (And even if you turn off filtering, it still looks bad). The few games that actually run tend to have glitchy sound and slowdowns, and games that use a 3d engine (For ex. Mario Kart and F-Zero Maximum Velocity) run awfully. I tried both gpsp+ and mgba, it’s the same thing. Is there anyway to improve this? Or, is this just because the gameshell can’t handle them?
