A new fw has been released by Dark Alex. I don't know if I'm gonna use it, I don't have many problems with 3.52 M33-4 so far, only PSPUAE does not work, whatever I try.
But f.ex. Monster Hunter Freedom 1&2 do not work properly on Oz' PSP with 3.71 M33-2, they freeze when trying to enter a character name, but they work just fine on mine.
Anyone some experience with any 3.71 fw?
