I edited my post, you might wanna look at it.
I used @NWPlayer123 's SARCPack and changed the value to 0x100 (it's the default value anyway), tested in game, weird glitches.
I'm saying 0x2000 may be the default for SARC, not PACK.but I looked at every PACK I could find and the common thread wasn't 0x2000 its just to the nearest 0x100...
