Download: JoySens v1.2 For 3.71 M33 CFW
From the author: I found time today to update my second PSP to 3.71M33 and test a method for making JoySens 1.2 available under that firmware. For now it seems to work fine, but it is next to untested atm, so I cannot yet guarantee it to work 100%.
At least this should give the 3.71 users something to play with for the time being. I'm currently working (when I find a little time every then and when) on JoySens 1.3 which will provide some new features, like a fix for analog sticks which don't even scale the stick range correctly (getting results < 127 or > -127 even when analog stick is pushed to the extents).
