Well I'm always on this site and never reallized I was a member haha so I decided to post. What are the Advantages from one custome firmware to another. I've just downgraded to 1.50 and I'm looking to run final fantasy VII (7) on the psp and I dont know what Firmware would be the best to "smoothly" run it on. I know some of them freeze durring the battle sequences and other parts and what-not. Also Can you change OE firmwares whenever you want or sucessfully downgrade back to 1.50. I'm just confused on the whole firmware thing. I dont really understand all the ins and outs haha... Help?
