I need to come out of the basement more though, it's always running out of black.
I used to do this with NetHack (back in the days when it was still just Hack), by writing a batch file that would change the system time. I had a list of the times that would give the best starting rings, wands, etc. for the Wizard, making me a filthy, cheating start-scummer.
Not sure if that still works or if the RNG is better these days. Save-scumming still works, though.
Not only did I test the whole "2 opposite directions at the same time", I rewired the joysticks. The Atari family, the TI 99/4A, and the Odyssey2 all used the same DB-9 connector, but with different pinouts. As our systems aged and joysticks died, we had to shuffle them from system to system.
My father taught me to use a multimeter to map out the different pinouts when I was 10 or 11. Radio Shack sold imitation Atari joysticks for like $5; with no eBay or Google, finding a replacement joystick for a dead console was a weeks or months long proposition. My friends with less technical upbringings would be shocked to find me playing Parsec or Munch Man with a 2600 controller.
Because no one wants to play a first person SHOOTER where you have no gun, only a walkie-talkie.
You're right, better safe than sorry.
Without life, Biology itself would be impossible.
