fMSX is an MSX emulator supporting MSX, MSX2, and MSX2+ cartridge files (.rom and .rom.gz) and disk images (.dsk, .fdi, .dsk.gz, and .fdi.gz). Place your files into E:\Others\fMSX. If your phone has no keyboard, or its keyboard is folded, always select the joystick option in games: the dialpad will act as a joystick.
