I have Pokemon Dash
I'm also a collector of Pokemon games - love them so much, but haven't gotten lucky enough to come across boxed versions for reasonable prices
the only ones I have boxed are all of the DS ones, and I have a few of the older games unboxed, but hoping to get them boxed soon.
I do have the Pokemon Gameboy and N64 boxed though
and lots of other Pokemon memorabilia
