Creating patches

If you have two source images of a game where one is unpatched and the other is patched, you can use Universal Dreamcast Patcher to create a DCP patch file based on the changes between both images. It can also apply certain patches to the IP.BIN file in the image such as enabling VGA mode, region free, and changing the game label.

1. Download Universal Dreamcast Patcher
2. Launch "Universal Dreamcast Patch Builder.exe"
3. Click "Select Unpatched GDI" to choose your unpatched source image
4. Click "Select Patched GDI" to choose your patched source image
5. Type in a name for the generated DCP patch file next to "Patch filename"
6. (Optional) Check the box for any IP.BIN patches you wish to set
7. Click "Build Patch"
