UAE is an Amiga emulator for UNIX. As far as I know it is the best amiga emulator for unix, and the windows port - winuae - is percieved to be the best for windows. It handles most, if not all, games and applications - but has problems with a few demos. It is a bit resource-intensive (my 733mHz CPU doesn't quite cut it), but at least it works - and using it for desktop-use (Workbench) is no problem at all. I suggest app-emulation
Created attachment 1000 [details] the uae ebuild
I was just told by Matthew Kennedy that you have discussed the problem of mutually exclusive USE flags on gentoo-core, and decided that a separate ebuild should be created for each of the available options. I'll upload the new ebuilds when I complete them.
