This is a two-step suggestion, so bear with me here. I noticed that you can select from all developers and publishers on the advanced search page, but you can't proceed with the search without entering text in the name field. If we could avoid entering in the name field to just search the database for companies, it would show every listing with that company selected. If this change was implemented, we could then have the developers and publishers hyperlinked to these advanced search query pages. The code for scanning for developers/publishers seems to be present already as evidenced by the advanced search working as intended right now, would it be possible to tweak the coding slightly to allow for this?
So if you were to click on Nintendo EAD on the Super Mario 3D World page, it would send you to the page that shows up when you would search Nintendo EAD in the Advanced Search.
