When I go to do that, it says "invalid config! ensure that all mount points are unique or set to none and ux0 is set." when i click triangle to save that to imc0 -_-I just opened my Adrenaline and I see you can change it to imc0, xmc0 and uma0.
So change your psvsd to one of those mounting points in Auto plugin imc0
Reboot
Then change Adrenaline "Memory Stick Location" to imc0spemu
And move pspemu folder from ux0 (sd2vita) to imc0 (psvsd) using vitashell or a computer.
