Super Famicom games made by non-Japanese developers are not common in Japan (but not always expensive).
I finally found a copy of Choplifter III! I found it in the bottom of a bargain bin at a used game shop.
When I saw it...I was like "NO..F'in WAY". I grabbed it with a quickness.
Now, I know this game isn't a classic or even cared about, but I love it!
Anyhoo, just thought I'd share
