The TT code is actually compatible with a 68020, so if you have a '020 or '030 processor accelerator then this code will be useful. To detect the processor, the CPU cookie in the cookie jar must be set. I assume that this is done by the accelerator, but if it is not then get in touch and I will try to write a program to set it for you.
The screen routines can currently handle any screen with a GEM driver and 2, 4, 16 or 256 colours on screen at once. Other setups are coded for but have never been tested. More than 256 colours on screen will definitely crash the program. Also the more pixels there are on screen, the more memory will be needed. For each pixel the program will need 2 bytes for statistics and memory for a blit buffer. For example, in TT medium res a pixel takes 1/2 a byte for the blit buffer and 2 bytes of statistics. With 640x480 pixels it needs to find 640x480x2.5 = 750K. ST low needs 156K and a Crazy Dots board will need about 4.5Meg. Most people seem to buy memory before a graphics card, so hopefully this is not a problem.
