Pocket Tennis JPN
This plays super different to the colour version. I was really surprised when i went from the coloured version to it. Feels quite mechanically different.
@underbutler Really, I've never gotten around to playing my color version cart, so just assumed it was a graphical update. Cool.
@shadowthreat I'm pretty sure the timings different. The colour version is probably one of the games I've played the most on the system.
