X68000

Battle Toads (Arcade)

The BSMT2000, or “Brian Schmidt’s Mouse Trap”,  was created by Brian Schmidt and introduced in the early nineties. It got used inside a few Arcade Games aswell as a number of Pinball Machines, like in the WhiteStar Hardware from Sega and Stern. The last Pinball Game to use it was Terminator 3 in 2003. Being an AudioDSP the Chip is all PCM/ADPCM based and does not allow sound synthesis.

Brian Schmidt himself composed music for lots of the Games using the BSMT2000. He later played a large role in designing the X-Box / X-box 360 Audio Architectures.
