GenMDM 103 had a serious flaw - the channel numbering was off. Channel 5 was DAC, instead of 6. Channel 9 was noise, instead of 10. And so on.
This fixed version of GenMDM 103 firmware will fix this issue.

seb.tomczak@gmail.com
=====================================================================================
Special thanks to: Freezedream, Lazerbeat, Aly James, Tanikugu, Paul Slocum, Christian Haines, Celsius, Dot.AY, 10k
=====================================================================================
Firmware v103 Version Information:
* Added YM2612 and SN76489 data capture mode
* Added YM2612 and SN76489 data acquire mode
* Added TL Equal mode
=====================================================================================
Firmware v102 Version Information:
* Native MIDI 5 pin DIN support via user-end hardware modification
* This is via the UART RX PIN, found on digital pin 7 of the Teensy board
* More cohesive handling of SSG-EG in terms of mapping - every OP and CH is catered for
* Storage and recall of 15 different RAM-based instruments for VERY quick instrument changes
* Reduced the sample storage ROM area by 2KB
* Simplified and restructured sample code and sample storage ROM area
* The current samples are just some 808 samples - looking to add user-assignable samples
=====================================================================================
Firmware v101 Version Information:
* Added: control of YM2612 FM voice 3 mode
* Added: control of SSG-EG mode
* Added: control of test registers 0x20, 0x27, 0x2A and 0x2C
* Trimmed code
=====================================================================================
MIDI Channel Sound Chip Mapping
* YM2612 FM sound chip is mapped to MIDI channels 1 - 6.

GenMDM Version 2 PCB 5V Jumper Function
The GenMDM Version 2 PCB contains two main changes to the hardware compared with the Version 1 PCB. These changes are:
• A 5 pin DIN MIDI input connection with associated optocoupler and components
• A 5 volt jumper
The function of the jumper is as follows.
When the jumper is connected, as shows in the photo above, then the SEGA console will power the GenMDM hardware including the 5 pin DIN MIDI input connection.
Use this jumper in the connected position when using the GenMDM with a traditional 5 pin DIN connection. Do not use this jumper in the connected position when using the GenMDM with a USB cable at all. Never connect a USB cable to the GenMDM unit when the jumper is in the connected position. Doing so may damage the GenMDM.
When the jumper is disconnected, as shows in the photo above, then USB cable will power the GenMDM hardware. The 5 pin DIN MIDI input connection will not be powered, and a traditional 5 pin DIN connection will not work.
Use this jumper in the connected position when using the GenMDM with a USB cable for MIDI data or for firmware updates. This will provide 5V to the GenMDM hardware via the USB cable.

How to: Update the GenMDM Firmware
2. Locate and download the GenMDM firmware update file. This file will always have the name of GENMDM_NNN.cpp.hex, where NNN is the version number. The file type will always be .cpp.hex.
3. Open the Teensy loader application, and drag and drop the .cpp.hex file. You can also go to File > Open HEX File.
4. Click on the 'Auto' button.
5. Connect your GenMDM interface via a USB cable, and click the tiny black button on the top of the interface. If your GenMDM interface and SEGA is hooked up so that you can hear the sound, you should be able to hear the updated version loading sound. This indicates that the firmware has been loaded successfully!
GenMDM Firmware v101
Firmware v101 Version Information
* Added: control of YM2612 FM voice 3 mode
* Added: control of SSG-EG mode
* Added: control of test registers 0x20, 0x27, 0x2A and 0x2C
* Trimmed code
