It is a custom ROM only for PAL Amigas with a 68000/68010 @ 7 MHz.
The challenge is that is does not use any RAM (the demo runs on an Amiga 500 without DRAM, without both CIAs, and without Paula). The screen is completely filled with the CPU (Racing the Beam).
The ADF can be used to kickstart an Amiga 1000 (PAL only). Emulation requires a very accurate, cycle-exact CPU and DMA simulation (e.g. WinUAE 5.0.0 or newer, vAmiga.net)
The 256K ROM has 11 frames, the 512K ROM has 22 animation frames.
The source code can be found on github (see external links).
