3.71M33-4 CWcheat doesn't load up in games

[gundam40]

Hi all,

Just updated my firmware from 3.71 M33-2 to -4, and activated the PRX's in the recovery menu.

However, when I try to get the cheat menu in game (I searched for the games in the db file, it's there. E.g. SD G generation), I can't. I tried holding it for 3 to 10 secs, no dice.

I'm using a PSP slim, with a genuine Sony (bought from Bestbuy) 8 gig card running 3.71 M33-4.

Any help would be greatly appreciated
