hello guys... i am need some help.. i have build a few days one arcade (like vewlix).. and the system.. its a xbox 360... its working lovely.. but... i have some problems with some emulators... like SNES or GENESIS (few i try).. because to enter in the MENU settings of emulator.. need to press R3 and L3.. but in the ARCADE game.. i dont have those keys... only the default keys (8 buttons + back, start and HOME)... SO i ask... have any way to change the shortcut in emulator from (r3+l3) to (r1+r2+l1+l2) or something like that?! ps: i canot change in the settings... i think it need to be changed in ".XEX" file... but... i dont know how do that. regards
