what is so good about firmware 1.50?
-sorry, i’m newbie-

the video isn’t that interesting too, he’s just showing off his limited edition crisis core psp slim. that’s all.

OMG. Dark Alex is AMAZING!

Well.. back in the old days, version 1.00 and 1.50 were the only official firmwares that allowed you to run homebrew. This is when the term “downgrade” was first used. There was no custom firmware back then, so everyone used 1.5.

When the slim came out, it wasn’t capable of running 1.5, because 1.5 didn’t have the special drivers needed to run on the slim.

I find the 1.5 kernel kind of pointless. developers SHOULD start developing homebrew for the 3.xx kernel. But it’s still and interesting concept.

I find its pointless too. Just develop for 3.xx

Im certainly not dying for 1.50 kernel support.

There’s many developers who quit the scene. And their programs were developed for 1.5 firmware.

ok i got a psp slim and my virson is 3.90 and i really want to play gba roms and stuff but nobody will give me a straight ancer on how to do it or if i even can do it sombody please help me out i would be much appreceated

well can i down grade my psp 3.90 to 1.50

@ Zach:
Try using GPSP (just google it)
If you have 3.8 m33-4 or -5 it should work.
(This is my setup on a psp slim)

You need to find a GBA .bin file, and your own ROMs. While I can’t post help for that here, if you need help finding any of this, my email is willprah [at] gmail [dot] com

fuck me baby

Zach, you need a universal unbricker

here is a link to a pretty good guide

try asking on the PSP – Mod and firmwarer forum of afterdawn.com

here is a link to the universal unbricker

and after that is successful

thats when you do what Dixie Flatline said

One more thing

there are many good Homebrew out there that crash when you try to play them in any CFW…that’s another reason why DAX is developing this new idea.
