In 2010, Selbi created a hack that ported Green Hill Zone to Sonic Crackers. This was a simple proof of concept level port of Green Hill Zone Act 1 from Sonic the Hedgehog. These days, I dabbled around in level porting and wanted to see if I could get something in Crackers. Green Hill's been done, so why not a more complex level? Sonic 1 to Ristar shall wait until more is known about the Star compression format. Here is Chemical Plant Zone from Sonic the Hedgehog 2, with the main layout of Act 1 ported to Sonic Crackers. Navigation in the level will be challenging thanks to how Crackers handles collision planes, so be sure to debug around! Provided are two ROMs, one without Combi, and one with Combi. Have fun! Source Code 10/29 Update: Fixed Combi build not chaining the characters together properly.
