Thanks Barf,

- I had been to globalcache and couldnt find them there
- i'd love to take Smakodak up on his offer, but unfortunately I'm in the US which (i'm guessing) makes shipping costs high

So it looks like I'm left with trying to guess.

To get a little guidance; the power toggle example above. NEC1 code given is
0x37CA, 0x0CF3

When I try to convert them to decimal, what do I input?
0x37
0x37ca
37
CA

.... or is that (sadly) going to be part of the guessing game?
