Amstrad 6128+ cartridge demo - Ranked 1st at Alchimie12 - 2017
Best to be seen on a real amstrad 6128PLUS, it needs a built-in 128k config, hence modified 464PLUS motherboards may work as well but stock 464PLUS or GX4000 cannot run it. When initialising machine, a test is done for memory expansion compatibility and IM2 bug support. This will guarantee a proper execution of the demo and display a message with almost all emulators, warning about proper support, as the SID sound replay is awfull with all emulators (except ACE).
This Demo clearly needs you to have a C4CPC cartridge.
This is pronounced CRTC cube.
It was praised for its awesome Music featuring some Electric Guitar sampled sounds, smooth animation and 16bit styled effects and palette, and really impressed Atari and Amiga fans at the compo.
