The information for VCR/0162 is available at
[Link: hifi-remote.com]That includes the fact that some of the commands require EFCs based on VCR/0454.
Many VCRs that use this command set have a few functions that aren't in either 162 or 454 and those need either JP1 or learned signals.
For the 0454 functions, you can change the setup code to 0454, then define key moves for the functions you want, then change the setup back to 0162 and the key moves you defined remain connected to 0454.
