I recently picked up a PSP 2000. It's hackable as far as I know. I've got an 8gb Memory Stick and a Pandora's Battery coming, but I decided to go out and pick up Monster Hunter Freedom Unite for 16$. Now, I've got Firmware 3.95 on here. I've heard that Pandora's Battery will be able to install custom firmware onto any version, but the thread that tells me that was made back in 07. So, I really need to know. Monster Hunter forces me to update to 5.03 or later(Will this update to 5.03, or just simply the latest version?) if I want to play it, and I'd rather not wait until my stuff comes to play it. Once I update to 5.03(or if it makes me, later versions), can I still mod my PSP?
