This is a hack of Vs. Super Mario Bros. that allows the game to be run on a standard MMC1 cart with 8KB SRAM. No custom hardware required!
It also adds the following features:
-Pre-game menu that allows you to set dipswitches and reset the high scores
-High score retention (when using battery-backed SRAM)
-Correct NES colors (Vs. hardware used RGB PPUs with scrambled colors)
