Actual help needed with DSPTool

[legoj15]

Hello, I've been trying to get DSPTool to work to generate dsp_code.h. I have figured out how to decompile DSP .bin files dumped with Dolphin (which just turned out to be the same file dumped along side the .bin file), but reassembling them usually leads to an error along the lines of

Code:

1 : 0000 0000      nop          ERROR: Unknown opcode Line: 1 : -

More than likely, I'm feeding it the wrong file, but if that's true, then what is the right type of file?

What I first tried:

• use
  ./dsptool -d gamedspfromdolphin.bin -o output.txt
  
• then
  ./dsptool output.txt -h dsp_code
  

Didn't work, so I did this:

• ./dsptool gamedspfromdolphin.txt -h dsp_code
  
• then a whole bunch of other attempts
  

Any help would be appreciated. I'm trying to compile a current version of DSPSpy to use on my Wii via the Homebrew Channel (alternatively, if someone could compile a version that's newer than the one on the forums {it's from 2012, and the last commit to DSPSpy was late 2017} that would alleviate my issue   )
