I was thinking about a Relocalization of Puyo Puyo on Genesis with music updated to use different instruments and actual drum samples from Dr. Robotnik's Mean Bean Machine instead of the original Japanese version which uses the noise-based percussion.
Source of Unused Stuff for Puyo Puyo Relocalization: https://tcrf.net/Dr._Robotnik%27s_Mean_Bean_Machine_(Genesis
) and look at sound test.
Puyo Puyo title screen from the Arcade Version would be reused for the Relocalization hack of Puyo Puyo for the Sega Genesis and the voices from the Arcade version will fit into the Sega Genesis.
If so, don't forget to add David Javelosa if you are using instruments from Dr. Robotnik's Mean Bean Machine into Puyo Puyo for the Sega Genesis.
I've never seen anybody do a romhack of Puyo Puyo on the Sega Genesis so it would be great to see a Puyo Puyo Relocalization hack.
