the epsxe emulator has a script that links all files in /usr/lib/psemu/plugins into .epsxe/plugins. Sofar so good. Now only a few of the psemu-* ebuilds put their stuff into that directory. the other ones put it into /usr/games/lib/psemu/plugins This seems kindof logical but since the epsxe script doesn't look there they become unusable until you move them to/usr/lib/psemu/plugins
upgrade all your psemu stuff, they all go into /usr/games/lib now also, update epsxe to -r2 ... i missed merging all the changes to the script with -r1
