Spike damage behavior

From Sonic Retro

Revision as of 18:42, 26 January 2008 by SOTI (talk | contribs)

In Sonic the Hedgehog for the Sega Megadrive, there is a bug where spikes can kill you even if you have rings. After falling on spikes, Sonic loses his rings and "bounces" away. If the row of spikes is wide enough, Sonic will fall back onto the spikes and be killed (as he no longer has any rings).

Fixing the bug

  • An official ROM hack was released as part of Sonic Mega Collection, called "JP2", where the spike bug was fixed.
  • drx actually created his own ROM hack before the release of Sonic Mega Collection, with the spike bug fixed. He later released the source code, or rather instructions for fixing the bug in an ASM file (disassembly). drx's bugfix has been implemented in Hivebrain's Sonic 1 Plus and South Island Adventure ROM hacks.
  • FraGag made a tutorial on how to fix the spike bug, it is avaliable here.
