Sonic Meets Tetris
To play Sonic Eraser on your Sega Mega Drive (the Japanese Genesis), a gamer needed the Mega Modem (seen here), a subscription to the Sega Meganet service, and a Sega Game Library cartridge. The player would then dial up the Meganet service and download Sonic Eraser and save it on the Game Library cartridge.
Despite all this hullabaloo, the game has very little to do with Sonic aside from the Sonic sprite seen here standing next to the puzzle playfield. Still, it’s a little-known part of Sonic lore.
