>>43528330>>43528321I do realize it relies on a lot of assumptions, don't worry. I'm trying to use the words "probably" or "most likely" as little as possible because it's all pretty much just speculation from reading source code dated almost half a decade later from where these things could've taken place, and extrapolations from actual released material that was produced during or around the time these games were very different.
I don't mean mentions of Mew in-game, I mean mentions in the game's code. The part about it being re-addedbafter being deleted is true, its data is defined in a completely different place from the rest and uses a lot of special code to be handled, is the actual data (name, appearance, in-game abilities) what I think was planned from the start, then cut and readded.
Other two curious things to note is Mewtwo was hastily moved to what was originally a bird's dungeon, and apparently was originally meant to appear on top of Silph. Co. according to HC's data (this is what I mean by now worthless: I can't directly reference the file where this info comes from because I'm still combing through the code, so I'm documenting pretty much everything from scratch. Don't worry, I'm not putting any speculative content into them. It's the reason I was waiting to even add translations)
pic related, here's the part where mewtwo gets called a bird. It also gets called mew for some reason.
