These are all the patch files released so far by Pentavision for DJMP Clazziquai Edition and Black Square.  Extract them to /PSP/SAVEDATA/ULKS46189DAT and ULKS46190DAT directories, respectively, on the same memory stick as the game save files.  The ULKS46189LINK directory is created by link disc mode in BS and may also be extracted to /PSP/SAVEDATA to skip a mildly annoying 3-minute 1-time setup.

Once extracted, turn on data access in the games' menus to enable these patches.  They are supposed to help a few different problems, including poor framerates (which still feel iffy to me) in CE and the otherwise horribly bugged 6-button arcade mode in BS.
