DLDI No-AutoPatch

From DLDIWiki

DLDI No-AutoPatch is used to patch a .nds with a DLDI driver, destroying the numeric "magic cookie" that patchers use to locate the DLDI area, so that autopatching firmware doesn't replace the driver. This is especially useful when starting a program from a SLOT-1 card that autopatches .nds files, such as R4, where the program should read and write the card in SLOT-2.

Version 0.9 of DLDIrc adds the same functionality.[1]
