Thanks, but I have the correct folder structure. The problem seems to have something with the fact that for the PSP 1.50 firmware revision, the build has to be done differently or something. I have two folders under PSP/GAME:
MAME4ALLPSP
MAME4ALLPSP%

MAME4ALLPSP contains the "main" EBOOT.PBP and all related folders, etc.

MAME4ALLPSP% contains a smaller EBOOT.PBP (134KB) only. I'm guessing this has to do with some exploit that is necessary on that firmware version?

So to conclude, I think someone needs to generate the second smaller EBOOT.PBP file somehow for 1.50 firmware version???

What's the speed like for an average game?.

I merged bublbobl.zip with boblbobl.zip and now the boblbobl.zip (on its own) boots up fine everytime.

Im on custome firmware 352 and i only have one folder with an eboot and not two. If your on 1.50 firmware you will need to kxpoit the eboot to make it work (like what you just mentioned).

Thanks for pointing me in the right direction. I was not aware that it was a relatively trivial task!

PS: I used this tutorial, though it seems there are even easier tools out there to accomplish it.

I guess you probably need the parent rom as well as the clones to get some games working... try merging them into one.
