First thank you for support picodriver in OFW6.20.

You have to detail more if you want us to help. You should attach the dbglog 
file. Also:

Do the error reproduces with other emulators?
What error do you got when saving state? 
Is picodrive source code available?

picodrive source code: 
http://notaz.gp2x.de/releases/PicoDrive/PicoDrive_135src.tar.bz2 (that's the 
latest 
one I could find).

Haven't looked yet but I'm assuming the save does a rename/move, and we need to 
estimate secIoRename, so that's probably a reason why it's failing. There's 
probably 
no workaround for that except that fat-in-file driver we talked about

ah, another possible reason: mkdir(SAVE) or something like that is probably 
being 
called. I have a manual workaround for that and I'm working on it.

No, FCEUltra saves state successfully

What error do you got when saving state?
SAVE FAILED

Is picodrive source code available?
Yes, http://notaz.gp2x.de/releases/PicoDrive/PicoDrive_135src.tar.bz2

This doesn't only happen with emulators. I usually play Squaro and this happens 
with it 
too. Progress is automatically saved, but since last revisión, every time a 
play, 
progress is lost.

On the other hand....picodrive works fine to me...

Hmmm, I'm not sure I fixed anything regarding savestates, maybe you're just 
luck with
syscall estimations :)

In r77 it didn't work, now in r79 it works perfectly both for PicoDriver and 
Snes9x
(where it didn't work also)

Thank you, and keep up the good work ^^
