Limit on # of platforms a game has shipped on...

I'd like to add SAM Coupe to Prince of Persia and Lemmings - but the box to add a platform on the main page isn't showing up when I edit it (presumably because there's too many?). Is there any way around this?

You're not the only one having that trouble. Check here

@reverendhunt: They should use this opportunity to intelligently organize that section of the infobox. The platforms should be listed in order of release, it's insane to see a classic game pop up as a PS4 game first.
