I am so glad I ran across that cover art site. I had completely forgot that DS game cases had slots for GBA games. As such, I'm picking up all my GBA games out of their pile, sticking them into DS cases, printing out the properly proportion covers, cutting them out, and so on. I'm happy with the results! Yeah, I know I'm not the first, but can't I be happy about it? And yeah, I know that's a tiny collection, but I know some of my GBA games are somewhere... I'll get them all eventually!
