Found an issue with my program. Since it doesn't read the MD5 hash, it never writes it. This will be a problem for playback.
I need help in parsing the three Hashes. Otherwise, things will not work correctly. I know to start reading bytes at, offset 0x071 for MD5 Hash, Offset 0x0E5 for IROM Hash and 0x0e9 for COEF Hash but how can I get them into an ASCII format?

Dur! If the Hex Value is read as a string, then I got the MD5 hash. The SFV for IROM and COEF is also written in Hex.
The DSP Files (IROM, COEF) will be noted as "Offical" or "Dolphin" Based on the Hex Value I get.
On the positive, I have some Gamecube Controller data being read correctly. I still need to handle just about everything. But at least you can see the Analog Stick, L and R Trigger, and C Stick values (0-255)

Very cool! Excited to see how much farther you can take the editor!

You should really read the entire header and write it back, including parts that are expected to be entirely 0, so nothing will be lost if anything is added to the header in the future.

1.4 released.
Fixes some bugs like not writing MD5 hash values or IROM/COEF hash values. You can set them too.
Also added the start of reading Gamecube input data. So far, the Analog stick, the C Stick and L/R analog values are being read. Actual button data is not done yet. Saving controller data is NOT ready yet.

I have yet another odd question.
The L and R triggers have an analog value, and if that value is 255, the L and R buttons are pushed. What is the Minimum value required to make the L and R buttons trigger? Is it only 255?
Edit:
I can now read a single Gamecube Controller data for a selected frame. Now to setup up multiple controller reading. Writing will come after I verify reading.

Another question I have is the Change CD Marker.
What controller(s) get that value? What happens if all connected controllers say, "Change Disc"?
I think all connected controllers say Change Disc. Can anyone confirm this?

Just 255 i think.

No, just the first one to be polled after the disk change is triggered. If all of them have the disk change bit set, then it will attempt to change the disk once for each controller. Which will be annoying if the disk cannot be found automatically because it could prompt the user to change disk multiple times.

Have you considered using a change number (1.0.6) instead of the minor version number (1.6)?
I am using the same system of numbering that DTM Reader and BizHawk use. Small bug fixes are Current Version.Minor version. While major changes or new features incriment the version number by 1 and minor becomes 0. I started at 1.3 so there's no confusion with DTM Reader.

How do you find a frame's offset in a Wii .dtm? If I recall, GC is frame# ---> hex*8+1024
Write a program to parse the file. The length of the data for each frame is variable.
For a short movie, is there a ballpark formula? I can still sort of read input if I get into the general area of the dtm in HxD. I did it previously with an SMG2 TAS but I can't remember how I got to it, lol.
Depends on the game. Open up the dtm and see. Some games change reporting mode constantly, others don't. The format is 1 byte indicating the size of the data, followed by the data. Some games may use one reporting mode on the health and safety screen, and then change it, and never again, which would make it easy to calculate. You'll have to see on a case by case basis though. You could also just hack dolphin to display the current byte, and play the movie back and see.
Edit: actually i'll just write a quick program to calculate it, won't take long.
Is there any way to see all the input from the .dtm in one column or something? And add no-input frames? I need to add some input in the middle of the movie.

I'm pretty sure there isn't, however, I've been working on a movie file editor of my own, and it should do what you want it to. You can find it here.
