To make a long story short, I broke my Game Boy Color last night, which I used for 2xLSDJ with my Pocket. I mostly used it for WAV samples, because it was a glitchy version that didn't play well with any pitch bends.
I've decided to just get a DMG finally, because I figured I could get by without a prosound for a while and get close to the same sound I was getting from the Color with the prosound mod.
I have one coming to a local used game store later this week, but I was wondering if there's any way I could make sure it's not CPU-02/03 before I buy it. I doubt they'll let me bring a tri-wing screwdriver in and take it apart before I pay, so other than bringing an LSDJ cart with me and seeing if it chokes on WAV samples, is there any way for me to know what I'm getting?
