Emulators crashing PSP (3.52 M33-4 CFW)

Wonder what I'm doing wrong. Originally it was only DGEN now and then, and e[mulator], but now that I've gotten rid of e[mulator] (no save support for NGPC as well as various other follies, and RIN is so far better anyway, except the crashing, which was present either way) and moved my GBC games to RIN, they still crash. Nothing happens, my games will just freeze and the PSP will reboot back to the XMB. Like I said, it only happens in a few games...so far once or twice in Bahamut Lagoon for SNES (running on SNES9xTYL 0.4.2me++) and a bunch of times in various GB/GBC ROMs, as well as Shining In The Darkness on DGEN.

Any reason as to why this happens...all help would be much appreciated.

Oh and I'm new here. :)

Hmm, perhaps it helps if you restore factory settings (i.e. erase flash1). But the most important thing I wanted to tell you:
NO ISO TALK!
And no, even when you own the original UMDs you're not allowed to talk about them.

By the way: Welcome to the forum!

Ha, oh yes...oops. I'll edit that out.

Will restoring factory settings revert my firmware?

no you you will need to re-install you firmware

sometimes restoring default settings solves some problems if not, then format flash1

Restoring default settings did not help...how do you format the flash1, and will I lose any data?

re-install your firmware through recovery mode

...and what would that do exactly?

it will format flash1
