Classic video games meets ultra portability. MAME (or at least a small portion of MAME) has been ported to the 5G iPod (includes the video and nano). Currently it has no sound support yet and about 70% of original speed but those are small issues they plan to work out. Support for 4G iPods should be around the corner. Should play any game that was based on the original Pac Man hardware (Z80 based, most Pac Man variants, Crush Roller, Pengo, etc.). I'm pleased!
