I've got a 2.7ghz g5 powermac with mOS on it and I'll never look back
Crap, neither would I!
For those looking for some fun on the Sega CD, I'd suggest checking these titles out:
First and foremost, HEART OF DARKNESS. It takes place in the Another World/Out of this World universe.
Bother LUNAR games if you are into RPG's. Actually all the RPG's on the Sega CD are worth your while I'd say.
POPFUL MAIL if you are into side scrolling, platforming, hack and slash, RPG's.
SNATCHER for a cyber punk Point and Click Adventure.
SPIDERMAN VS KINGPIN.
SONIC CD (my personal favorite of classic Sonic)
SHINING FORCE (predates Final Fantasy Tactics)
EARTH WORM JIM SPECIAL EDITION
ECCO THE DOLPHIN
Oh man, too many to list. This emulator has brought a LOT of good things to the table!
