FINALLY I CAN START MY FIRST BADGE QUEST! SOFT RESETING FOR THIS (Shiny Mudkip) !
I'll tell you guys if I find any difference between this NFR version and the normal one but I never heard of it. I'm pretty sure it's the same, just the front sticker that's different, but whatever!
Also, if you need help to distinguish an official GBA pokémon game from pirated/botleg/copy, I'm your girl, just ask away! Better be sure than sorry!
tl;dr
GOOD LUCK FOR YOUR SHINY AND BETA STUFF HUNTING!
