Can't get clock in Pokemon crystal to keep time. Psp 6.20 pro cfw emumaster 3.0

[Gmdfunk]

Been messing with pokemon crystal. I start a game, input time, save, quit and reload. Time and day are now wrong but will progress properly in real time, just wrong day/time.

Tried again but set psp cfw clock to 24 hour time. Same result.

Tried again with Pokemon silver, same result.

Tried with older versions of masterboy and emumaster, same result

Tried resetting clock with game shark code, same result.

The only way I have been able to get Pokemon clock right is to offset the psp clock to compensate for the time difference. But now my psp clock is wrong.

Pokemon clock works fine in homers rin, but it won't save emulator settings like button layouts so I don't want to use it. Anyone have any info to fix this either emumaster or homers rin
