Thanks to this site and a JP1 cable I have been happily using a number of URC7562-B01 remotes for several years. However, with changes of eqipment I have now run out of keymove space and so looked to see if an extender was avaialble.
Unfortunately, whilst there is one for the URC7562-B00 there is not for the B01 variety and reading the posts it is clear that the B00 version is not compatible. Therefore, I have decided to try and create an extender for the B01. I have familiarised myself with the assembler code of a couple of existing extenders (the B00 extender doesn't actually change the amount of keymove space but others do).
After many searches of the forums (fora?) I cannot find any clues on how I go about tracking down useful ROM entry points and or tips on identifying register usage, hence this post to ask if anyone can give me some pointers.
Help needed to create URC7562-B01 Extender
