Hiya!
From posts here about 3rd Gen RNG, it seems that you're the go to person for this kind of thing. So, I want to try RNGing a shiny Mew in the Japanese version of Emerald and I was wondering, is it possible to directly ID/SID abuse in Emerald? Some of the outdated online guides say that it's not possible, but I'm hoping there's a breakthrough that hadn't been posted.
