kinda off topic but im fiddling around with adding 7z support into xSnes9x. i have it working somewhat but in some instances 7z decoding requires > 80 megabytes of ram allocated, yikes
i can use virtual memory tricks to make it work, but then it becomes a question of feasibility - if and i stress if with VMM it takes say less than 10 seconds to extract and load a rom from 7z then id considering putting it into the next build.
otherwise its a pipe dream
