Downgrade PSP 2.50 to 1.50

I think you have to go to 2.80 first, but offer no guarantee's!

 

Hmm it sounds like either an extremly messed up downgrade, or rather no downgrade at all.....hold the R button when you turn on your psp, and you should go into the "recovery menu"

choose configuration> and make sure "enable no-umd" is err...enabled..that may help you in loading iso's without a umd in the drive

also, did you use the popstation software to convert the psx iso's?

also, did you install the right type of homebrew, as in, the 1.50 Kxploited-one which comes in two folders (NAME and NAME%), and put it in the /PSP/GAME150 folder on your memory stick?

 

He says 3.02 OEA 3.02 OE A didn't have PSX support. 3.02 OE B and 3.03 OEA have PSX Support.

 

3.02oe-a/b had psx support..thats why i upgraded to it, 3.03oe offered psx compression and various bug fixes

 

A had support for Playstation Store PSX games. B added support for your own ripped games. Then .03 A added compression, as you say.

 

Ok, i'm now on 3.02OE-B and PSX games now work like a charm, still ISO/COB files will show on the memory stick game menu but not load/go blank screen when i try to boot them even with no-umd enabled and an umd in the drive.

I even reset back to 1.50 and then did the 3.02a and 3.02b. I'm sure i'm missing something, anti what exactly do you mean, because i saw something about that in the readme but i'm not sure howto do that
