XDelta Wii

This is an attempt to create a homebrew app for the Nintendo Wii that can patch dumped games, without the need for a computer.

Requirements

• Wii cable of homebrew
• An original dump of your source game (e.g. from CleanRip)
  • Place on the root of your SD/USB device named game.iso
• Your xDelta-format romhack / patch file
  • On the root of your SD/USB device, named patch.xdelta
• SD Card or USB drive with enough space for the original game, patch, and output files
  • Must be formatted to FAT32 (NTFS support coming soon...)
  • GameCube games, 4 GB or larger is recommended
    • 1.36 GB for game.iso (original game dump)
    • 1.36 GB for patched.iso (patched output file)
    • ??? MB for patch.xdelta (the romhack / patch file)
  • Coming Soon: Wii games (single-layer disc), 16 GB or larger is recommended
    • 4.7 GB for game.iso (original game dump)
    • 4.7 GB for patched.iso (patched output file)
    • ??? GB for patch.xdelta (the romhack / patch file)
  • Coming Soon: Wii games (dual-layer disc, e.g., Super Smash Bros. Brawl), 32 GB or larger is recommended
    • 8.5 GB for game.iso (original game dump)
    • 8.5 GB for patched.iso (patched output file)
    • ??? GB for patch.xdelta (the romhack / patch file)

To Do

• Actually implement the xDelta library functions
• Add NTFS Support (required for patching Wii ISO files as they exceed the 4GB FAT file size limit)
• Port to GameCube
  • Change WPAD to PAD inputs
  • Replace Front SD / USB with SD Gecko
