Lists are severely worked content delivery methods, but darn it if TheZZAZZGlitch’s video lists aren’t actually really interesting. These are all early Pokemon game glitches and their application, and usually go quite deep into their code.
In the most recent of these (the ninth, 10 minutes long) one of the examples has to do with exploring glitched, out-of-bounds Pokemon boxes. These can cause writes to unexpected regions of memory, and very strange glitches indeed. But one in particular, if it happens, causes a write to a region of memory that causes an unexpected bankswitch, meaning, suddenly a whole swath of the game ROM isn’t what the code expects. In 99% of cases this would cause a sudden game crash end of story, but in THIS case the code that ends up executing doesn’t immediately crash the game, and not only that later in the code path, the bank gets switched back, and the code path is in such a place that it actually recovers, and the primary effect is just some glitched graphics, all completely by chance. Huh!
Here is that video, and if it’s interesting, the others (9 video playlist link) might be to your liking too.
