Pair Match A88 has been fixed. Dropping the voltage down to 8V or 9V worked and I got what I think is a good dump. You could see repeated bytes in the old dump, and now that's gone. I dumped it 6 times and got the same CRC so I am gonna say it's probably OK now.
I replaced the files in the pair match directory.
I also redumped vtech invaders- it looks a lot better now. I lowered the voltage a little bit on this one too and got consistent data then.
