Astro Rabby JPN
@Mako98 unfortunately this one is quite expensive apparently (didn't actually know this when I bought it)
@shadowthreat oh :/
@Mako98 best thing I can suggest is be lucky enough to get it from an import shop where they don't know its value, as that's how I got it. But in any case its a very interesting game, quite unlike most other typical platforms on gameboy.
