Hello everyone, I'm here to ask for some assistance on RNG'ing a shiny feebas on a copy of Emerald using the 3DS's virtual console to play the game. I was wondering if there are any special considerations that differ from RNG'ing a Pokemon compared to GBA, such as extra timing from booting up the game or framerates or something. I'm mostly looking at I'm a blisy's guide on this (https://www.youtube.com/watch?v=11BMMcd33kw), but I don't really have a ton of technical experience in RNG manipulation besides Cute Charm glitch in gen 4. Any input is appreciated. Thanks!
(I'd like to bring this Feebas up to modern games so I'm probably going to use PKSM/PKHex to move it from the gen 3 games into my gen 4+ cartridges.)
