Solder connections to the back of the main board where the custom chip used to reside:

The Arduino mega I used for the large number of IO pins, I'd do that differently now:

Channel 40:

Tried to catch it between channels with the scan function on, it didn't go well:View attachment 48759
I never did recreate the channel 9 switch function. Just too lazy to wire it in.
Now here's the sad part. The disk the Arduino sketch was saved on took a dive a few years ago. If I wanted to change anything now I'd have to start from scratch om the programming side.
Looks great on the outside ! I thought you'd have extra frequencys too though. I like your approach though and thanks for posting ! I found a different brand of this Console 5 in Aussie land and someone had did a unique cool channel mod I love !
