heya im new to the scene, just got M3-real perfect bundle, its running most game boy advance game fines but im having
problems with mario advance 4 (nes mario bros 3) it runs but the sound is messed up BAD, and the "classic nes series" gba carts, mario bros, legend of zelda etc, they wont run at all say "gamepak error turn off the power" im running the latest system files for m3 real version 3.1, anyone know how to make mario advance 4 run with correct sound and how to make the "classic nes series" gba carts run??

after alot of researching i discovered the fix for classic nes series carts, they have to be patched with "ips" files. after learning about that and doing that now they are working wooohoo. now if i can just figure out how to correct the sound problem in mario advance 4.
