Yes, it's actually incredibly fast especially with GBA games. Runs Pokemon FireRed / Mother 3 flawlessly.

It struggles to play DS games. I tested it with MKDS and the game was slowed down by about 15%. I haven't tested GBA games on this emulator and I probably won't because I don't have any. 5/10

For gba its probably fine but it ran ds games pretty badly. Stick to rom injections for ds

cool
