FFIX aka Final Fantasy IX 9 Boots to black screen - psp

hi all,

i'm not a noob, so i'm tearing my hair out at the fact FF7 and FF Anthology play fine on my PSP but for some reason, FFIX boots up to a black screen. I get the PS logo, then a black screen.

I have tried different popsloaders with no luck.

I'm on 3.52 m33-4. I have just downgraded from 5.00 m33-6 because i didn't like it.

I used to be able to play FFIX on my 3.52 m33-4.

Can someone send me the known working files for FFIX please. I really want to play this game.
