iMAME4All experimental support for iCade Thanks to Todd Laney Replace mame file included and put on /Applications/iMAME4all.app directory NOTES Best way to use iCade with iMAME4All is in fullscreen portrait mode, hit the option button and choose options. the onscreen controls will fade out when you start using the iCade buttons to get on screen controls back, just touch the screen. if the iCade is off (the fake coin slot light is off) just hit an iCade button or move the joystick. (you must have paired the iCade via bluetooth before) when the iCade turns off, the SW keyboard may popup and then backdown, this is normal don't be alarmed iCade KEY MAPPINGS TOP: [RED/COIN] [BLACK/EXIT] [BLACK/Y] [WHITE/B] BOT: [RED/START] [BLACK/OPTION] [BLACK/A] [WHITE/X]
