Gaming PSX playback between firmwares

[Devil May Cry]

Hey guys.

I've been making some PSX EBOOTs as of late and have noticed that a lot of them don't like to work on 5.00 M33-6, irregardless of the POPs. The wierd thing is, they all work fine on 4.01 M33-2, even on the original flash. What's the difference between the host firmware and the POPs firmware being applied? I would love to revert back to 4.01 M33-2 on my main PSP (so I can use Ultimate Black again), but Bleach Heat the Soul 6 won't load saves on 4.01 M33-2.

Decrypt your saves with Deemer as you switch firmwares to solve that issue.

Your PSX problem seems odd though.....which games and what happens? Running a new pops via posploader should be identical to actually being on that firmware.

These ones were 2 Digimon Games: Digimon World and Digimon Digital Card Battle. The suggested POPs were 3.52 and 3.90 respectively but neither worked (all POPs versions made them instantly freeze, although original flash I at least got past the POPs list).

That sounds like you've just got the incorrect popsloader for 5.00M33.
