SD2SNES Gameplay: DSP and ST010

Now, that all of the setup and stuff is out of the way, we're going to show you some gameplay from the SD2SNES. In this video, we show you the gameplay of the DSP chips and the ST010 chip. The DSP had 4 versions, the most notable was the DSP-1 chip found in Pilotwings and Super Mario Kart. While Johnny Blaze explained two of the chips, here's what they do: DSP-1: Used as a math coprocessor in games such as Super Mario Kart and Pilotwings that require more advanced Mode 7 scaling and rotation. It also provides fast support for the floating point and trigonometric calculations needed by 3D math algorithms. DSP-2: Its primary purpose is to convert Atari ST bitmap image data into the SNES bitplane format. It also provides dynamic scaling capability and transparency effects. DSP-3: The chip assisted with tasks like calculating the next AI move, Shannon-Fano bitstream decompression, and bitplane conversion of graphics. DSP-4: Primarily helped out with drawing the race track, especially during the times that the track branched into multiple paths. We also take a look at the ST010, which was used in only one game, but it's nothing but a rip-off of a classic SNES game. You have to SEE it to BELIEVE it!
