I remember getting my first Mew during the DVD release of the Lucario Movie. There was this event at Toys R Us where some guy simply traded you a Mew. They also had free Pikachu paper hats and a raffle for the Movie which came with a special Mew Trading Card. These Live events were kinda neat compared to the "go to GameStop for this serial code"
How was Mew obtained back in R/B/G? I know it wasn't obtainable through in-game means...
Nice. That sounds like a comfy memory
Legaly, events but rarely anyone had access to those. Most people used Game Genies for that. Years later after the Mew Glitch was found most people did that.
I went to the Training Tour '99 where I handed my Blue cartridge to a person who put it in a slot on a machine that put a Mew on it. I recall they told everyone to make sure there's a free spot in their party, which is where it put the Mew. They also gave a paper certificate with each Mew.
The event also had someone showing off the upcoming Yellow on a big screen using a Super Gameboy. I remember someone asked if you could make Pikachu so mad it zaps you, and he said we'd have to wait for Hey You Pikachu for that. I think they were also demoing Stadium.
I wish they had came by where I grew up but I never got word. and I gre up in the SF Bay Area so I would imagine there would be one stop somewhere there. But I got my Mew by the old link cable glitch where you traded with somebody and the person who got the undesired pokemon would just turn off his game after the trade and they kept their traded Mew.
The one they had at Training Tour '99 in the US looked very similar. I didn't get a look at the front of the machine though, so idk if it was the same Super Gameboy with modified cartridge setup, but they stuck the cartridge into a slot on the front of it very much like that.
Basically they would have distribution carts full of Mews that they would just manually trade to you.
