Digimon world 3 problem

i'm using popsloader 3.71M33 to run the game
but sometimes when i walk into a shop or go to another map, the screen became black and the psp restart itself
how can i solve this?thx

Upgrade your firmware (5.00M33 is a good start) and try using a different pops to play the game.What program did you use to covert the PSX game to an eboot?

i'm using 5.00M33and i use psx2psp to convert the games

Try a different version of pops.

3.71 says it's supposed to work, 5.00 says it freezes when changing areas.I haven't personally tried it, but there are many different versions of pops you can use with popsloader.

wow~that's website is really useful~
it seems the problem has gone after i changed the game ID
THX a lot~^^
