Here’s a sega megadrive/genesis sequencer that controls the joystick and bends.. It syncs to the gameboy so the characters in the game move to the music that is comming out of the gameboy..the game that has been used in the video rom on my site was hacked. sonic and tales was completely re-worked, the layout is different and you can see the flowers have turned into gameboys…
