You can either make whatever changes to these settings after copying and pasting the [RADIO] and [RadioMenu] sections over the originals in the Mmsstv.ini file, or just copy/paste and change the few settings needing a tweak from within the program itself.
IMPORTANT: Do not modify the file while MMSSTV is running, it will overwrite it when you exit, so exit first, modify, then re-start MMSSTV.
This section is near the middle of the Mmsstv.ini file:
(Note – Change PortName and BaudRate to suit your system!,
also Cmdxx=148 is the CI-V address, 148=94h – the default for IC-7300, check in your rig under MENU>SET>Connectors>CI-V>CI-V Address. If it has been changed from 94h, convert the hexadecimal number to decimal and change Cmdxx to suit)
[RADIO] PortName=COM4 BaudRate=19200 BitLen=1 Stop=0 Parity=0 flwXON=0 flwCTS=0 usePTT=0 ByteWait=0 Cmdxx=148 CmdInit= CmdRx=\$FEFExxE01C0000FD\ CmdTx=\$FEFExxE01C0001FD\ FileGNR= OpenGNR=0 PollType=3 PollInterval=5
This next section is at the bottom of the Mmsstv.ini file:
Note: This is set up for Australia. If your country has different standard frequencies, the format of the commands is:
This is actually 2 commands together for setting frequency and mode.
The first command is \$FEFExxE00578563412FD:
\$FEFExxE0 – start sequence (xx is changed by MMSSTV to the number in [RADIO]> Cmdxx, E0 refers to your computer),
05 – set frequency, 70563412 – 12.345.670 MHz, FD – end sequence.
The second command is \$FEFExxE02600010101FD:
\$FEFExxE0 – as above, starts sequence and addresses radio,
26 – set VFO, 00 – Set CURRENT VFO, 01 – Set to Upper Sideband (change to 00 for LSB), 01 – DATA mode (set to 00 for normal SSB – non-DATA), 01, Filter setting 1 (The widest filter if you haven’t changed it in your radio)
Note: in USA on the 30 meter band SSTV must be a narrow version (500 Hz from what I’ve read). Aswell as selecting a narrow mode in MMSSTV,
You may want to set the Filter for 10.132 to ’03’, the narrowest by default, and manually adjust this filter to suit.

All that’s left is to set sound card to USB Audio Codec (the rigs built in sound card), do this inside the program.
Note that while I have set all this up and made sure it works, I haven’t tried to have an SSTV QSO yet. I probably will at some point but even for monitoring the frequencies the above guide will help as you can change to the standard frequencies from the menu.
