I have tried to play bad games I found on 2ch that never idled the CPU though and used a gigabyte of memory. I'm not even sure how they managed to accidentally run at 100% CPU all the time and still be kinda responsive.
They also really like old versions of windows. I think I read somewhere that ME\2000 is still pretty popular there. They don't really like open source either. I'm guessing that this lets them get away with making it as shitty as possible while high on crazy yakuza designer drugs because no one ever sees it.
