Robotnik's Revenge

Hack of Sonic the Hedgehog 2

This is a hack which adds a boss attack which features all the bosses from Sonic the Hedgehog and Sonic the Hedgehog 2 for Genesis. The hack is based on Sonic the Hedgehog 2 for Genesis. The hack takes place in Death Egg zone and the objective is to get a good time and ranking. There are two modes, time attack and survival mode. Time attack mode grants infinite lives and has rings placed in-between battles. Survival mode has only three lives and has no rings whatsoever.

The patch is in xdelta format due to shifted data resulting in IPS patches containing original code. The ROM should be in BIN format.
