Its out, but it doesn't has specific support for 3.80M33 yet. If you are using 3.71 on PSPSlim, I have the stripped down package here for you. For 3.80M33, you will be sharing the 3.60M33 package because I find that works best for now.
Extract the package to your seplugins directory and you are all to go. If you have other plugins, do edit the game.txt, game150.txt and pops.txt accordingly.
The packages has been updated with cheat.db as of 19/01/08.
