Metal Sug 6 still not working!!!

Hi,
I installer 3.10 OE-A2 on my psp because I read about a debug for Metal Slug 6 on Metal Slug Anthology. There's a problem. MS6 doesnt' work!
Why?
Every dump I tried doesn't work! The a2 update is for Burnout Legends, Metal Slug 6 and other games who crash with this error 0x80020148.
WHy???
Please help me! The others ones Metal SLug works (1,2,X,3,4,5...) but MS6 doesn't!

turn off NO-UMD and plain modules.

I don't understand, in NO-UMD mode doesn't work? If I use the UMD mode will work? What are plain modules?

well NO-UMD mode has a lower compatibility rate just because some games check the UMD drive in a different way, and plain modules has to do with how the PSP deals with encrypted / decrypted modules.

you can turn both off in the recovery.

great! thanks
