Quoted from Kingjowjow:I've tried holding down the HS reset button for a good few seconds and it did nothing, do i have to hold down for like 10 seconds? Will there be some kind of noise or signal it puts off when it does work and the high scores are reset?
You'll need to hold the button for about 5-10 seconds. The display will say "High Scores Reset" and a basic sound effect will go off. That's what happens on my 1990 Rollergames (also a system 11c game) anyway.
