>>36448625If it makes you feel better I traded away my event Victini to get my Black 2 shiny charm - still wish I had finished some other way. But I'm very grateful I kept "core" games in the 3rd-5th gens, if that wording makes sense - I have one version where I keep all my stuff (for example, Black 2 for 5th gen), and then I can just trade everything into that file when I feel like restarting another game. Stuff like that has let me keep EV trained monsters that I had way back in 2009, and stuff that I can't get anymore like dreamworld females in 5th gen.
For 4th gen that game is Soul Silver, since the item layout screen is nice, I like being able to have all 16 gym leaders in one big room for training shenanigans, and I like the GB music thing for when I feel like I'm a mood for a different soundtrack.
