Try running from the alt GAME folder
Try out GAME4XX or GAME5XX thats PSP/GAME4XX or PSP/GAME5XX
do not put number where XX it supposed to actually have XX in the folder names
Myself I just use a 2xmicro SD to Pro Duo adapter that has apx 50GB storage (I have 2x32GB MicroSD's in mine and finding it hard to get 50GB's worth of good games on it and no wires needed)
