I realize most of this info is available from various sources (including these forums). I just wanted to put all the info in one spot with simple step-by-step instructions. Hopefully, this process will make it easier for those attempting them in the future.
How to get Famicom Disk System (FDS) working
The Famicom Disk System is a Japan only addon system for the Japanese Famicom. It requires a BIOS to run but is fairly simple to add compatibility to the Retro Freak and have one more system emulated. I have not been able to get actual FDS connected and working to a Retro Freak so no ROM dumping and no save game transfers. Emulation works fine though.
Step 1: Obtain Famicom Disk System BIOS. Just google it. Make sure it is named "disksys.rom" and not in a zip file. You may need to rename the BIOS. Some people have had to capitalize it other systems seem to prefer lowercase. "DISKSYS.ROM" worked fine for me. If capital letters don't work try lower-case.
Step 2: Create a folder on micro-SD card called "BIOS" and place disksys.rom in that folder. The folder structure should look like: <SDCARDroot><RetroFreak><BIOS>disksys.rom
Step 3: Obtain FDS roms. Google is your friend here. Make sure they are unzipped and have the extension .fds
Step 4: FDS roms can be placed in the same folder as NES/Famicom roms. My folder structure is set up as <SDCARDroot><RetroFreak><Games><NES>*examplegamerom.fds
FDS games will show up in the Famicom [FC] "folder" on the Retro Freak but in the actual games list will have the prefix [FDS] instead of [FC]. Just select your FDS game and launch it as normal.
If you need to flip the side of the disk (most games require this) the default is Option+Start using the Retro Freak controller. Or you can set it to whatever you'd like with Hotkey Configuration.

How to get English language cheats
Cheats are available for the Retro Freak but are in Japanese. For those unfamiliar with the language this can be a problem. Luckily the Retron5 uses the same basic cheat file structure.
Step 1: Download the Retron5 cheat file from Retron 5 site http://www.retron5.i...Cheats-v1.2.zip
Step 2: Open the zip file and extract the folder "Cheats" located in the Retron folder
Step 3: Open the Cheats folder and rename the XML files as follows (codes-gba.xml doesn't need to change):
codes-gameboy.xml ---> codes-gb.xml
codes-genesis.xml -----> codes-md.xml
codes-nes.xml ----------> codes-fc.xml
codes-sms.xml ---------> codes-mk3.xml
codes-snes.xml --------> codes-sfc.xml
PC Engine cheats are not included in the Retron 5 since it does not support that system. You can put the Japanese Retro Freak cheats in there if you'd like. But you results may vary unless you're playing Japanese games and understand Japanese to select the correct cheats. If you don't want to mess with Japanese or just don't care about PCE you can skip to Step 6.
Step 4 (optional): Download Retro Freak cheat file from http://www.cybergadg...ofreak_code.zip
Step 5 (optional): Open the zip file and open the "cheats" folder. Extract codes-pce.xml and put in your customized cheats folder.
Step 6: Place your custom cheats folder on your micro-SD using the following folder structure: <SDCARDroot><RetroFreak><cheats>
Note: I haven't personally tested the GBA cheats to be compatible with the Retro Freak. I will when I'm back home and edit this post.
