what!? you dont buy a GBA emulator for 5$, you just got ripped off
GBA emulator is free, Of course in the adrouid store, you have to pay, but its a RIPOFF, dont buy soemthing that is already free
all you have to do is google," GBA emulator for android" download the VPK ( android package) and then google," GBA roms for android" and there shoudl be a list...with lots of games
TL:DR : I downloaded it off google and i have 5 games including "The legend of zelda" the minish cap", Pokemon ruby and sonic advance 3
..im currently trying to downlooad and play pokemon hacked ROMS, its pokemon fans who make their own pokemon games. it seems much more intresting than the Officiial ones...
examples: pokemon naranja rom (really fun costom rom
