Made a mistake earlier when I got Dicing Knight Period added. I put PC, when I actually need Wonderswan added as a console. thanks

You are the moderator so you can change this kind of stuff right there :

I am unable to add new Platforms. The Wonderswan isn't on the list. If I can, I don't see how. Sorry.

I've added the WonderSwan to the platforms list.
