Yeah it would have been cooler if I had been able to keep it lol. Seriously it's the second shiny I've ever run into legitimately, the first one was a metapod or something when I was a kid. fml :D
I haven't really considered using JPAN's engine but I might if there are enough benefits. And lol yeah the speed in FireRed is really slow though for walking standing in place, the gif in my sig of the fairy fountain shows that :D
I guess it depends on how many OWs you'll need / whether you're using JPAN's Engine. If you don't need many than having a separate one for walking might be fine ^_^. I'm not 100% but the 'jogging' or 'running' choices might only use the two frames - the problem there is the speed though :/ the poor girl will get whiplash is she sways like that.
Yeah but if I do that then it's 3 frames not 2, the middle one being the standing sprite which I'd want to skip completely unless you're talking to them or if they're actually walking lol Idk, might be difficult to implement :P
