Yea I had it a while back and burned the ISO of it last week, started playing it again and realized it was a must own again. I have the Japanese retail but for once the US has a better soundtrack. Just glad I don't have to worry about region lockout with my new multicart. I bought the Japanese retail of Sonic CD as I didn't remember a region lock out when I owned a Sega CD before. Imagine my surprise when I tried to play it.. doh!! So if you ever want to play imports, just get a descent Sega CD memory card, or play ROM's on your Sega CD (I use an X Eye and it works fine also) get an Evermind flash cart. They rock and everythign is done via the CD add-on instead of a nasty parraell port eww!!! Ok back on topic just wanted to share my Sonic CD story for those who might make the same mistake...
