A bit late, but still,
I have been contacted by several forum members via private messages with some questions and some just to thank me for this tutorial. You are welcomed, always. And thank you for taking the time to thank me.
As far as i could gather from the posts here and PM's, the main and only point of failure for this mod to work was not cutting the line as noted in the second picture. Please DO CUT that line, it does not work without actually cutting it and soldering the wire on the 2 points shown in the third picture.
This mod was also tested on several other KRC1 versions and it has worked without any other modification.
I was also asked on how to do loops of a program, as goto and loop did not work for them, but i have no clue how to do that as i never needed it.
Thank you all
Tom
