> Nice. Any cool differences with the Bubble Bobble proto?
It runs on a Tokio/Scramble Formation PCB, which is lacking the YM3526 that produces music in the final game. Unfortunately the PCB currently has no sound. The sprite data is different; there are various sprites missing compared to the final release. There's also no protection MCU but that's not a big surprise. I'm sure tcrf.net will have fun with this once it's fully dumped...
