Does any one knows the correct pops version for HP1 and HP2 of PSone?

I am having a bit of a problem, there is an area where Neville Longbottom tells me about some possessed armours there is a library that is also a secret passage, if i try to access it the game crashes (a picture of the school in blue that means that i have discovered a secret area but i do not get a loading bar nor the game loads the next area)

The first game so far only accepts to be run on the 3.30 (which causes that the game does not reads my save) ,3.40,3.50, 3.51 3.52, all 6.xx and original from flash versions but the crash still happens, anything lower so far the game either refuses to start (3.80,4.01) or crashes (anything between 3.02 to 3.11 and 3.71 to 5.51)

If any one is interested i could load my save because the place is really close to the save point.

Running PRO CFW 6.60 on a PSP 3000, POPSLOADER v4g.

Or do i need? to swap the ID much like digimon world 2003
