Firmware screen meanings?

[blue_quartz]

Anyone knows what does the table on the firmware screen mean?

MAIN : V 1.00
BKUP : V X.XX
MONI : V X.XX
ADJD : V X.XX
EXTD : V X.XX
CPU1 : V X.XX
SH : XXXXXX
ST : XXXXXX

(copied blatantly from Ricoh's support web page)

Main, Bkup (Backup) and CPU1 probably need no introduction, but what about the rest? I'm guessing SH is for shutter count, since I see 4600+ on my GX-100?

Unfortunately, I don't know most of them too. But you are right about SH (total shutter count), and ST is count of photos taken with flash.
