The code you posted follows the NEC protocol. (See Barry Gordon's document in the Classic Pronto Files Section, User Documentation Subsection on the Pronto Hex IR format)

To use the codes from Yamaha PDF as input to MakeHex, you need to know 3 things. 1) The Protocol (determines which IRP file to use), the Device Number (decimal), and a set of Functions (decimal range).

From the PDF, note that 7C is hexadecimal for 7*16 + 12 = 124 (decimal) and 83 is hexadecimal for 8*16 + 3 = 131 (decimal).

So, you can use MakeHex and the file NEC1.irp to generate a set of codes. Edit this file to use Device 124 and then generate all functions 0..255. From there, you should be able to take function 131 and test it to see if it will work. Bet it does!!!
