Hmmm, wonder if there's a difference with the N-Go and Next for that particular driver? I am using the Next mouse driver that comes with 2.07k...
It is possible those games are reading the Kempston ports and doing their own thing - I originally did that in basic (I do use it on the title screen to read the mouse button) but the mouse driver was more efficient, faster and, eh accurate 😂
Thanks for the heads up on that.
