This question is sparked by the following three questions:
- Why does the Minus World exist?
- Why do parallel universes exist in Super Mario 64?
- What is the cause of Trent's circuit board strategy?
All three are ostensibly similar in that they observe that a bug exists in an old game, and ask for an explanation of how the bug causes the behavior (or, at least, imply that that's what they're really looking for).
The community's (and my) reaction to the three questions is distinct in each one.
The Super Mario Minus World question is highly-upvoted (although that's also because it was on the HNQ list), and has two good answers that explain why the bug behaves as it does. The Mario 64 Parallel Universes question was less warmly received, and has a single good answer. The Goldeneye question was not well received, and has been closed. (For the record, I was one of the close voters.)
My reaction to the first is that it's a famous bug that became a part of gaming lore, that an explanation of how it works is interesting, and that the code behind the game is simple enough to understand to be able to make this explanation. My reaction to the second is that it's a bug that makes speedruns faster and is potentially interesting to some people. My reaction to the third is that it's a bug related to invalid input, so of course buggy things are going to happen, and what goes on behind the scenes isn't particularly interesting or relevant.
Retro games and games consoles are on topic. Retro coding is on topic. Are questions about bugs in retro games on topic, and do we need guidelines about them?
I'll post one answer that can be voted on, but, as a fairly casual user of the site, I'm more than happy to see what the community comes up with.
