I'm building a portable mame 4 player, and wanted to run it on a small laptop (amd dual core c70, 1.33ghz, 2gb ddr3) and mala lags on startup and shutdown. Yes it technically works, but I'm not going to settle for a 4 second startup and shutdown.
Let alone the laptop wont run mk3, ki2, sf3 or games of the like without the sound chopping awful or frame rate being terrible.
Now if I wanted to just run pacman and tetris....no problem heh
