In this repository you can find the retro game ROM hacks I have created.
The repository is structured like this:
Console/Game (Region)/Name Of The Hack/Name Of The Hack.xdelta
Console/Game (Region)/Name Of The Hack/README.txt
Console/Game (Region)/Name Of The Hack/screenshot.png
The .xdelta file is the patch itself and can be applied to your ROM file using the DeltaPatcher.
