When I am playing some games the games go slower and slower sometimes it crashes How do you make it faster? I am using no$gba 2.6a with no$zoomer and one more: where can i find an english inazuma eleven DS rom
Usually emulators requires a computer that is more powerful than the actual console in question, for example, a PS2's emulator requires a PC way powerful than PS2.
Which game was it? Try changing the Emulation Speed on no$gba, and make sure the 3D renderer is 'nocash'. Might as well check the EXTRA option on no$zoomer to see if the EX5 was enabled.
You can also try to lower the sound quality. And changing the emulation speed from the config. And if you use no$zoomer, don't use any filter on it.
