A longer term fix is to soak the whole key pad sheet in Fuelite (Petroleum Spirit)

Dummy here. Reads to me as a regional brand name and an ambiguous generic term. Would soaking in naphtha work?

Played the DOS version to completion, enjoying every bit of it. Then the TurboGrafx-16 CD version with its satisfying cinematic reveal of the big plot twist. Really wish I could play more games like this!

Congrats and mad respect! Was reading some of the details in your comments in the other thread. A function generator is definitely on my want list, along with a CRT analyzer (if I happen to find a deal on a good one).
