I recently received Kaboomer's copy of Super Mario RPG - one that works on a Supaboy. I don't have my Supaboy to test right now, but I can confirm from watching his video that it's the same cartridge. Having said that, when I opened up both copies of the game that I have, the insides are using the same PCB revision, though the chips look slightly different. I honestly don't know how to differentiate between a clone-compatible copy and a non-working copy. Sigh.
Someone told me that if there's just a 2 digit number, then it's a first rev. and the later ones had an "A" stamped too. Guess I'm wrong then. I just found out that the ones that say "Made in Mexico" work? Figures with my luck...
