GFCA-188~90: Power Pro Kun Pocket Music Stadium

[Medina]

I searched a little on GameFAQs for Pawapurokun Pocket, then just Pawa and still couldn't come up with this game. Then I thought of some other things "pawapurokun" could be since it's just the pronunciation of kana and came up with pawa trying to say "power". I searched Power Pocket on GameFAQs and I seem to have found this series. Wikipedia seems to list it as the Power Pro Kun Pocket series. None of them seem to have been released outside of Asia.

Would it be more appropriate to put Power Pro-kun Pocket in the represented products field, or does "Pawapurokun" come from somewhere official? It looks like any other romaji trying to represent English words, but Wikipedia mentions it as the "Pawapuro" series sometimes so I'm wondering if this is some official thing.
