eboot problems

hi, i have a '3.10 oe a' psp, and I'm trying my hardest to find a way of playing 1.5 eboots.
the reason being, is that there are new quake 2 port versions out, and I've been waiting for them for ages!
and now i can't play them. I've tried converting the 1.5 eboots into 1.0 but it doesn't work. does anyone know of a good way to run 1.5 homebrews on a 3.10 oe a psp?

through recovery set game folder to 1.5 kernel and just drop the 1.5 folders in the the game folder and run it

Or you can put then in GAME150 folder. 1.50 Eboots must be placed here in OE firmwares.

woah! dark alex's firmware is better than i thought! thanks a bunch! I'm gonna play me some quake 2 :D
