You can use MakeHex to generate the RC5 signals in the form of Pronto Hex that begins 0000 (the form the Universal Browser understands). You can use IrPanels or hex2ccf to convert the result to a ccf file.

I assume you still have the list TMA published to tell you the device number you need before running MakeHex and the function numbers you need for selecting which buttons to drag in Universal Browser.
