While Paul was coding on the DMA implementation (you remember the MODplayer ?) he was thinking about a way, to show, what the MEGA65 is capable of.
I'll hand over to Paul and quote, what he wrote on Youtube:
Here is the current state of our work-in-progress game to demonstrate what the MEGA65 Retro Computer is capable of. Apologies for the lack of narration, as the kids sleeping nearby. This is a true C64 compatible 8-bit computer. It has no frame buffer. It has no modern CPU. It is all 8-bit processing and our custom-chips implementing this. The texture painting is done using fractional and stepped DMA memory copies, that effectively stretch or compress the line of texture data being displayed. The text overlays are hardware composited using the VIC-IV's raster buffer. While we only have a few textures in there at the moment, it will be possible for us to have a few hundred textures in such a game (for MEGA65s which include the standard 8MB RAM expansion module, which includes DevKits and production machines and some FPGA boards), and still have it all fit on a single 800KB floppy. Visit mega65.org, c65gs.blogspot.com or info.forum64.de to follow the action.
So without any more talking, the MEGA65 team presents MEGAMAZE !!!
