Hatari requires, in order to function correctly font8.bmp in /usr/share/games/hatari This file is under src directory if hatari tarball. PS. It would be nice if a gpl'ed tos image from http://emutos.sourceforge.net/en/index.htm is included.
I fixed the font issue in cvs so you should be able to use hatari now. I'm going to keep this bug open and look into the TOS issue.
I've added games-emulation/emutos to CVS and changed the hatari ebuild to use it. I made it a separate package in portage since it's usable by several atari emulators which may end up using it eventually. I think this covers the rest of this bug so closing.
