GBA doesnt have its own categories and also has a leaderboard,so why its a platform here?

and also,add 3ds and new3ds,since you can play this on those consoles (a dont own a 2ds so i cant tell if it can run ds games)

Thanks for pointing this out. These were the platforms that were there when I became moderator and I didn't get round to changing them. I have updated the platforms to add 3DS, New3DS DSi and 2DS/2DSXL to the list.

GBA is a seperate game. Because it’s not a port as is the DS. Please be careful NOT to add those.
