2 short videos showing Doom II and Cannon Fodder playing on the Acorn RISC PC 700 with a StrongARM CPU.
The RISC PC doesn’t have native OPL3 type audio, so there is no music for Doom II – but you can play audio from a audio CD if you wish. However, Cannon Fodder uses PCM audio, so you do have some music. Audio is quite similar to the Commodore Amiga.
