WIP:
  • 0.104u7: Anonymous fixed indirect palettes in the System 32 driver. This fixes SegaSonic The Hedgehog graphics finally.
  • 0.101u5: Anonymous fixed SegaSonic so it works as well as the prototype version (still major graphics issues) - Game now playable.
  • 0.86u4: Curt Coder changed description to 'SegaSonic The Hedgehog'. "The" is Sonic's middle name according to "The Ultimate History of Video Games", p. 428: The "T" in Sonic The Hedgehog is capitalized. Sega Marketing wizard Al Nilsen had the "The" registered as Sonic's middle name.
  • 30th January 2004: Roger Sanders emulated the protection in Segasonic (Japan rev. C) - still crashes due to video emulation bug.
  • 0.78: Changed description to 'Segasonic the Hedgehog'.
  • 0.67: Swapped cpu2 roms ($280000, 380000).
  • 0.64: Changed visible area to 416x224.
  • 0.63: David Haywood added Sonic (Japan rev. C) (Sega 1992) and clone (Japan prototype).

history Sega Sonic The Hedgehog (c) 1992 Sega.


A scrolling, isometric racing game for one to three players featuring Sega's legendary mascot, 'Sonic the Hedgehog'. Sonic's nemesis, 'Dr. Robotnik', is once again intent on World domination and is preparing to launch his latest attack from his new island base, Eggman Island.


When 'Sonic', 'Ray', and 'Mighty' drop in to thwart his plans, Robotnik catches them with one of his devious machines. After finding themselves imprisoned in a tower, the trio break free onto the island, and proceed to make their escape and try to defeat Robotnik and his evil plans.


Sega Sonic's gameplay retains elements of the original console games, such as Sonic's ability to jump on the heads of enemies to kill them. The golden rings that Sonic collects are also included. Each level is littered with Dr Robotnik's devious traps; with lava flows, collapsable platforms, locked gates etc. all serving to hamper Sonic's progress.
