Starman was kind enough to test out the emulator for us with his Playstation copies of WC3 and 4 and take a few screenshots. He found that the game overlays the controls on the bottom of the screen (an option that can be turned off), but that the program also supports bluetooth gamepads!
The titles were run on my Samsung Galaxy S I9000 (Running Android 2.1 Eclair) and I ripped the PSX CD's to .BIN files using IMGBurn and my original UK copies of WC3/4 which you just copy to your phone memory and then select the file within the application itself. Should be noted you require the PSX BIOS file for the emulator to function. -- Regards, Starman
