Banana Patcher is able to apply on-the-fly Preloader patches to System Menu without installing anything to the NAND. Some of the code was taken from Waninkoko’s Menu Patcher. Banana Patcher needs an IOS with trucha bug (any cIOS will work).

Useful for:

Play your GC imports
Copy your copy-protected saves to SD easily
Move Disc Channel

Changes:

added IOS selector at start (you don’t need a patched IOS36 anymore, just use any cIOS)
added predefined hacks (you don’t need the banana_hacks.txt file for main hacks)
added new hack files (thanks to marinos35)
