UMD won't play, old saved games don't work under 3.90M33-3

[Shaun P.]

I upgraded my fat PSP 1.50 to 3.40oe-a about a year ago, and then recently bought FF VII Crisis Core. After playing for a while, I thought I should see if there was a better cfw available . . . and long story short, I upgraded to 3.90M33-3 (and added the 1.50 kernal add on).

The upgrades all seemed to work properly, and my PSP identifies the firmware as 3.90M33-3. I have two problems, though.

The first is that my old saved games for Crisis Core no longer work; anytime I try to start them up, the PSP tells me that the data is corrupted. I tried re-formatting the card (still said old saves were corrupt); and I started a new game under 3.90, and the 2 saves I did in that game work fine, so I doubt its the card itself). (I also, unfortunately, don't have any other old saved games to test, so I don't know if this is specific to FFVII CC, or would be true for any game.)

The second problem is that, while all of my other UMD games work, for some reason my Sega Genesis Collection UMD will not run at all. When I try to play it, I get this error message: "The game cannot be started - the data is corrupted" I can understand files on my MS being corrupted (my original SONY 32 MB MS lost a bunch of data over a month ago), but I've never heard of a UMD being corrupted.

FWIW, I've already tried resetting flash1 and that hasn't helped with either issue

Thanks in advance for any help!

Probably the easiest thing would to be to reinstall 3.90 M33
and see if results stay the same.

Really, Crysis Core launched for you using 3.40 OE-A !!! well you could always revert back to 3.40 OE-A and see if the results are the same.

Try to access recovery menu and check over ALL those settings.
Make sure game kernel is set to 3.90 although, this wouldn't effect launching UMD operation.

You could use recovery menu to rip the UMD to PC via the memory stick option and simply launch the ISO from the game folder, if it can complete the operation you know your UMD is fine.

Tried that, and unfortunately, it didn't work. Thanks for the suggestion - any other ideas?

OK, I'll try that and let you know what happens.

I will definitely give that a try! Thanks!

What about formating flash1 and resetting the configurations?
