I'm planning to use Wah!Cade
I did setup a symlink to ./mame (home/emulators/mame), and created a roms folder under this one.
I haven't done anything else though.
Well, I created the config.ini file, but haven't started editing.
But is there something wrong with the Bubble Bobble rom? I do get an error on PC as well, but more a warning, and then you can still play.
After MAME, I am also going to install nestopia and zones.
I'm going to use Ubuntu 11.10 on a atom-computer. Hopefully it will be fast enough.
