Segapede

Segapede is an unreleased Sega Mega Drive action game that was being developed by Sega Technical Institute in 1994. The game was never officially released and wasn't known until gameplay footage and materiel was put online by developer Craig Stitt, who would later dump the rom online for Hidden Palace. The only existing prototype rom is notable for reusing graphics from Hidden Palace Zone, a removed zone from Sonic the Hedgehog 2. According to Craig Stitt, these assets were used as placeholder graphics during development.
