MAME controls in Troubleshooting Posted August 4, 2021 So i have Mame setup in launchbox/BigBox. I am using 228 emulator and 228 roms set. I am also using a homemade jotstick that has 12 buttons and an eightgate stick with a zero delay board. it works great. Some games will not let me use the start and coin buttons that i have assigned, but if i use the keyboard its no problem. in particular Express Raider. i am building a arcade machine so i dont want to have to us a keyboard to start the game any thoughts or solutions would be appreciated.
