If you have an interest for this kind of old nostalgia then you can download my demos here.
Thoroughly stable rasters in only 128 bytes !

This screen a pseudo sphere-mapping which only use 68030 : the code was done 2 years ago and it's a really crappy one. The Dsp is only used by the Replay routine. The sphere is about 200 pixels high and the screen is running in 2 Vbl.
