I really wanted one to collect myself. :/ (Was technically new...)

The same thing happened to me at first. It is playable on my Retron 5 since the region is set on Automatic to detect any code. At first glance, I thought it would've played on the Super Famicom. It's very similar to the Nes and Gameboy versions.
