This is a new version of the G-zero demo, I made this about 8 months ago, but now I want to make it public. This version doesn't need extra ram on cart, instead I'm using 16KB of the main system ram, so now the sise of the "map area" is 128x128 (instead of 256x256 of the previous mode 7 demos), because of this the "mode 7" graphics look now more "pixelated", but I don't think it looks so bad. Other advantage of this is that now I can use another 16KB to include a 2 player versus mode with split screen, horizontal or vertical. For now this is only a demo, but I want to make new graphics, new sprites, nothing related to f-zero series, a new game, and probably other name instead of "g-zero".
The previous demo, from 2015, used SRAM as a window into a larger bank of external RAM (a very crude form of memory paging) that would have been prohibitively expensive back in the day. This demo, however, is using completely stock hardware, capable of running on a standard cart as it would have existed back when the Genesis was real.
Mightily impressive stuff.
