JP1 Remotes

[120240VAC60HZ]

I got a good deal on a used Sony MHC-GX20 (From the Goodwill for $30) I like it for what I use it for (The Aux/Game input is going to my computer)
anyway it came without the original remote commander (as Sony calls it)
anyway I searched the upgrade files and I looked and I was able to get alot of the functions working but I still need a few select functions that are listed but will not work with my model
anyway I need the following keys in an upgrade file
Tuner Memory
Enter
Record
anyway I am cheating I am using my JP1 remote to program my harmony remote as it did not have all the functions listed for my model
also is there a way to get IR to recognize the JP1 Parallel interface in a 64 bit environment (Windows 7 64 Bit)

Thanks in advance
