This is a thread for uploading and discussing ROM hacks that have no known surviving mirrors. If you're looking for an old rom hack or have one that you can't find anywhere else than your computer, this thread is for you! I'll start by discussing this old Sonic 2 hack. This Sonic 2 hack that Cinossu made in 2005 includes new zones, new characters, and Sonic CD's time travel mechanics. Unfortunately, all download links for this hack have died, and Cinossu no longer has any builds of it. All that's left are these screenshots that were saved in the Wayback Machine. Spoiler: Screenshots If anyone here has anything related to this hack, posting that stuff here would be really nice.
