With Nintendo, it's always a double-edged sword. On one hand, they create really good games, but on the other hand, they are a shitbag company.

I don't mind that Dolphin is not staying on steam for whatever reason - they do have an auto updater and I can use any other cloud service to synchronize my saves - but seriously, just let them be, Nintendo...

Its not that much of a loss given you can still launch Dolphin from steam anyway. It just won't be on the storefront.

I don't really see the point of adding it to Steam in the first place anyways

TLDR

Because Valve asked Nintendo if it was allowed, and Nintendo said it shouldn't (pretty please), so Valve asked Dolphin to ask Nintendo if they could. Dolphin's team finds of obviously impossible to accomplish.

Not sure why it was coming to steam in the first place, made no sense. All it would do when you open it through steam is open the dolphin program, the games themselves weren’t being integrated into steam.

Just seemed like a bizarre decision by the devs that was always going to get blocked.
