This was converted from the Yamaha PAB website's PDF files for standard and extended IR codes. It is all valid codes converted very carefully with Yamaha's provided Hex converter. I've tested most of the Main zone and Zone 2 codes but if you find any that don't work send me an email with what you've found and I'll revise the database. this device library works for all Yamaha Receivers in the RX-V*65 series.
