Hacking Error 80000004 when running Persona 2 EP

[Kiyoko]

So, as the title states, I get this whenever I'm starting the game using POPSloader, selecting 4.01 pops. I created the Eboot myself using PSX2PSP version 1.4.2, by setting both the Game ID and Main Game ID to SLPS-2100 and using a compression level of 9.

The Eboot, created without changing the ID, opens up but it frezees so often during Boss Battles wherein you can't skip animation that it's barely playable.
Am I doing something wrong with the convertion?
I also tried to delete the save folder multiple times but to no avail.
I haven't had any problems with creating Eboot of other games, so maybe I'm missing something here.

I'm running CFW 6.60 PRO-C, and when I change the POPS version or disable the POPS plugin the game stays on a black screen.

Also, I was wondering if the PSN version, released in the US, does have the same freezing problems on PSP that the eboot has. If so, how does it work on PS3?

Some games jist don't work with psx2psp

that game works for me,

it's some glitch with psx2psp. you need to set the compression to 1 (it has to be 1, or some games won't start)
