Strange avatar you have there, but memorable
WHDLoad doesn't use any memory until you load a game. A lot of the games won't be able to run with 2MB, especially the multidisk games.
WHDLoad needs the RAM because it kills the operating system, loads the entire game into RAM and plays it from there. Then when you quit the game it restores the OS as it was before. Pretty clever stuff, but you really need a RAM upgrade to make the most of it.
