How do I play newer PSP games on Firmware 1.50?

OK, I recently downgraded my 2.60 PSP to 1.50.

Anyway, now 3 of my 5 games don't work, and I was wondering what I need to do to be able to still play them. Someone said something about a devhook, but I don't know what that is, how it works, or where to get it.

Could anyone help me out please? ^_^

All I can say is google. Ready-to-go.

Just emulate 2.6+ with Devhook...

EDIT: Sorry I didn't read it right..just download it from like psp hacks or something...

download devhook .46 and emulate 2.71:)

MSN me at [email protected] if you need more assistence. ;)

Or you can ask Kramer.. :D As easy as dragging two folders into your memory-stick..

OK, I got the devhook thing working, but I've got some questions about it.

First, under the OTHER catagory, there is an AUTORUN OPTION. What does this do? Does it mean that devhook will automatically run whenever I turn on my PSP, or only when I put in a game that requires a higher Firmware?

Also, I notice there is a SCREENSHOT OPTION as well, but I don't know how to use it. What button do I press to take a screenshot?

Is there a guide anywhere that can explain everything about DevHook? Cuz' there's like a lot of stuff in it that I don't understand.
