BTW, if you want any of what Yamaha calls "NEC" codes (which cover a lot more brands than Yamaha) and you have all eight digits (as they gave in their "32 bit" example) and you want the Pronto Hex for a Pronto (which understands the concise form of Pronto Hex, unlike URC Universal Browser etc, that understand only long form Pronto Hex) you can just prepend 900a 006d 0000 0001 in front of that 8 digit code (so you don't need MakeHex and you don't need Windows Calculator).
