Workflow:

• Edit the text source with extended/corrected function.
• "Handassemble", ie write the HEX codes and calculate offsets in same text file
• Reformat (a copy of) the text file to conform to the V01 format (one line of HEX digits)
• Run the V01 assembler ON THE BADGE to create the binary from the V01 format to create the V02 binary

• Reformat (another copy of) the text file to conform to the V02 format (zero or one HEX per line, whitespace, lowercasee allowed)
  • Easier alternative: create a shorter dummy test file (nonsense code) in V02 format
• Load the V02 and debug, by feeding a file in V02 format version

Rinse and repeat
