Original description, while not technically inaccurate, was stubby, dull, and poorly-written. This one should be look nicer and be a bit more flavorful, while remaining a tastefully-modest length.
This is a hack which enables a Super Sonic transformation in the original Sonic the Hedgehog for Genesis. Sonic can transform to Super Sonic by double jumping while in the air after acquiring all 6 Chaos Emeralds. There is also a cheat code to transform into Super Sonic without beating any special stages. Cheat codes can be found in the readme.
Tested on a ROM in BIN format. Not guaranteed to work on other formats. Use on the 1.0 version. The patch is in xdelta format due to shifting data resulting in a ips patch larger than the ROM file itself.
