FIFA 14 PSP file extraction

[jacknot]

I'm trying to extract game files of FIFA 14 for PSP.

I've extracted .big files using ea_big4.bms script, which gave me four files with .apt, .const, .o and .msh extension.
I guess I have to work on the .msh file but I don't know how.

Same with .db files, extracted using fifa14_futdb.bms, which gave me .dat files that I can't open properly.

Thank you.

Anyone has an idea?

Just some magic values (good for search on google):
.apt: Apt Data:64
.const: Apt constant file
.o: Linux shared file
.msh: SHPM ("Buy ERTS")

these .dat files are mostly database tables and xml files.
