Hey! Thats me. Yeah the 32 bit patch from
MWisBest in 2017 also works. The 1st post is the one's I was using since it more closely replicates the more limited RNG yields of Pokemon in FrLg and Emerald. Granted the 32 bit one would be the most optimal patch to hunt in, you might have trouble if you intend to port it up to newer gens if Bank or Home detects it the seed of the mew isnt supposed to be naturally generated in Emerald. But I highly doubt bank is smart enough to tell the difference, its just for anyone who wants to be on the safer side to use the first patch they built. Anyway, happy hunting!
