Here's a file that I found on Oppo's website that contains all of the IR codes in Hex format for the BDP-83 and
93.

Includes both Pronto shortform and learned hex codes in an Excel spreadsheet.

RS-232 control.

Commands for this device are available as part of a system layout file.

Mapped all the HEX IR codes for the OPPO BDP-83, put together all ready to merge.

Device code for new Oppo BDP-83 blu-ray player. I had created this one before URC added on to their files but theirs is badly broken. This one was derived from the file for their previous DVD players and adding the additional functionality for the BDP-83 using the "learn" mode for the MX-850.

Pretty basic, modded from an earlier Oppo CCF I downloaded from here, but does the job.
