Which I understand, it's all part of the nostalgia too. I do wonder one thing does it work on the JPN versions of the game too? Because they are distributing mews there in their pokemon centers through in game link cable. (I was wondering maybe simply because they don't have the glitch, but I can't confirm).
Most (if not all) glitches in the international versions exist in the Japanese versions. I wonder if the Japanese VC version uses the international versions or the original Japanese versions without bug fixes.
