i have just updated from 1.50 to 3.40 oe-a. i've been using devhook for the past year and decided to change. now i dont know how to run my iso's! people say just launch them from the xmb, but i don't know how? when i turn on the psp it just runs whatever disc i have in the drive. when i go to the xmb i have no idea how to launch iso's. i have an iso folder on my ms, and i do have iso's in there, i'm aware of all that stuff as i used it when i was running devhook. i've tried reading guides and stuff but nothing seems clear to me. any help would be appreciated.
