Pikmin disable archives trick
If for some reason the game is unable to find a file it is looking for in an archive, it will instead look for the un-archived version elsewhere in the Data Directory. This can be exploited to allow the un-archived copies of files left on the disc to be edited and recognized.
Paired ARC+DIR Files[edit]
Replace the DIR file with an 8 byte long file of zeroes. Optionally, the partner ARC file may be completely emptied file.
It is unknown if this works for pikiSeq.arc, as its DIR file equivalent is located in the DOL header.
BUN Files[edit]
BUN files can be deleted with no negative effects. Alternatively, they can be dummied out with 4 bytes of zeroes.
