Hi guys.
I'm trying to translate a game but I'm stuck with the editing of overlay's files. The game uses compressed overlays, so I decompressed them, edited the ARM9 overlay lba with the new file size and without the compressed flag and repacked everything, but the game freezes on some points of the game. Until now I didn't find a way to recompress the overlay's files and CrystalTile2 corrupt the rom of the game...
Someone can help me? >_<

PS. I decided to post here and not in Translate's section because it isn't a translation problem but an editing problem.

Already tried and the result is this:

If I compress an overlay with DSDeCmp and after I try to unpack it, the decompressor crashes... Seems that it won't to compress correctly
