On this topic:

I just recently found out about and put to practice the "8F" glitch method in the gen 1 Pokemon games that can be used to do things like tweak Pokemon IVs such that they will be shiny when transferred into later games, and rebrand the OT/ID of things like Mew so that they will pass the legality checker and be transferable into later games. I finally got all the prepwork and busywork done tonight, and I'm looking at a full set of shiny birds and Mew+Mewtwo in Home right now.

I'm sure it would be no issue whatsoever to get these things genned nowadays, but there's something strangely enchanting about doing the work yourself to get them via nothing but official/original software and taking advantage of their numerous glitches, instead of various 3rd party tools that came about later that just simply creates whatever you want.
