iCADE ----- 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/L1] [BLACK/Y] [WHITE/B BOT: [RED/START] [BLACK/L2] [BLACK/A] [WHITE/X] TVOUT: ------ Fixed 16:9 modes. Now you can set the amount of overscan corrections in options menu. If you like iPad 2 TVOUT mirror or you use and external 3rd party TVOUT app, you can turn off iMame4All native TVOUT in options menu. THANKS ------ Thanks to Todd Laney for sending me patches and testing, and Martijn Bosschaart who has support me to get the iCade HW.
