Sonic the Hedgehog Genesis (Genesis)

Hack of Sonic the Hedgehog

Description:

This is a hack of Sonic the Hedgehog for the Sega Genesis. It attempts to recreate features of the much disliked Gameboy Advance port of Sonic 1 called Sonic the Hedgehog Genesis. The hack has the following features:

  • Physics which closely match those of the GBA game, noticeable during Eggman boss confrontations as it is possible to bounce of the top of him.
  • Spin Dash which has slow animation and dust that appears slightly before the spin starts.
  • Background effects, like moving clouds.
  • Various bug fixes.
  • Skippable score countdown, momentum preservation, “Press Start” text on title screen.
  • Sonic’s sprite art and the life counter text are replaced with the different art from the GBA port.
  • All springs double Sonic’s max speed until landing after being airborne. All side-facing red springs act like yellow springs. To compensate for the lower speed, slope repel calculations aren’t performed after hitting a spring. Vertical springs erase all horizontal velocity not in a direction being pressed.
  • New feature: the scrolling is changed to give a better sense of speed and Sonic CD-style lookahead (not in the GBA port).

The patch is in xdelta format. The ROM should be in BIN format.
