A prototype of Sonic the Hedgehog Pocket Adventure for the SNK Neo Geo Pocket Color.

Notes

  • Pressing start at the Sega screen brings up a debug menu.
  • Contains two test maps for the action stages, and two test levels for the special stages.
  • The debug menu contains different level names for various zones, but the zones themselves have the final names in their title cards.
  • Some aspects of levels have collision problems (i.e the springs in Casino, and the rotating platforms in King Relics).
  • The boss in Death Egg Act 2 doesn't spawn a capsule upon defeat.
  • Some sound effects are missing from the prototype.

Features - Character Select screen that makes you able to select Tails and Knuckles - It's now winter in Neo South Island Zone. Sonic first meet his worst enemy, Dr. Eggman on an industrial scale creates robots out of ordinary animals and even friends of the sonic the hedgehog. Eggman does everything for a reason. He is driven by a passion to seize power over the whole world. For this he needs the Chaos Emeralds.

  • The ROM was obtained using the Tengu Neo Geo Pocket Dumper. Because there were quite a lot of errors in the process, the cartridge was dumped 16 times. 9 of the dumps were identical to the released ROM, 7 others had errors. The errors were in different places of the ROM, so it was possible to rule them out.
