They have a pretty dandy walkthrough.
I was clever enough to buy a 1.50, so I didnt need to use the guide thus I dont know if it is That helpful.
But even though people want there PSP's downgraded ( for emulation I suspect ), I would really think that they shouldnt. The 2.0 Version fixes Bugs, and makes them less likely to appear. Theres also more features, and I suspect in the future they will be able to handle things better.
But thus, Emulating Mega Man to my PSP is great, so meh. They balance each other out.
