Get ready for "ultraBooST", our first demo since STresSTeST in 2015!
This one is a little different, as it is not a plain Atari demo, but a demonstration of what would have been possible if the Atari had nicer screen modes and custom chips.
It is a showcase of an fpga based extension board developed and built by ultra. It provides additional screen modes and helpers and hence emulates some kind of custom chip like other systems have them by default. Except from displaying the screen data for additional screen modes everything else is just plain and optimised M68000 assembly code without the hustle of concepts like c2p consuming much of the available Atari CPU time. Even the music is classic timer based YM2149 sound. Ranked 1st place at SillyVenture 2k22SE.
Just check out the information files in the package to read more, even about the special version of STeem which provides an emulation of the additional screen modes.
