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. |
