Here is a list of the EXACT rom to search google for to make the patch work. If you are having trouble getting 
a patch to work, try using a rom with this exact title. If it still isn't working, you may need to check the hash below.

EACH ONE OF THESE PATCHES HAS BEEN CONFIRMED WORKING

For 4.5 and both of the 6 games, make sure you are using either the Japanese rom, with the patch labeled (J)
OR the prepatched English translated rom, with the patch labeled (EngPatched) for them. 

*NONE of these 3 games use the USA version, like all the other patches do.*

IF YOU GET AN ERROR WHEN PATCHING, IT IS PROBABLY THE WRONG BASE ROM

You can check the hash for your rom here to verify it is the correct rom:
