All times are on standard American NTSC systems, and I did not use
any cheat devices!
That means, unless I mention it:
I did not use any Game Genie type devices to get my high
scores.
I did not use any turbo feature on joysticks to get my
high scores.
I did not use any slow-motion feature on joysticks to get
my high scores.
I did not use any built-in cheat codes.
I may have used special tricks built-into a game, however. This includes
special shortcuts in Super Mario Kart, and jumping out of my vehicle in
Blast Corps to blow up a building.
