I'm not sure how many people there are that play RoR and own a
Microsoft Sidewinder 92626.
But, there are people out there that own and use old controllers. And, it's always a pleasant surprise, when you find out that someone has already created an input map for a controller you own.
So, if you have the skills and would like to contribute, I'm sure someone will appreciate it.
Creating a good input map can be a lot of work though, and it's not very fun.
If you do end up creating the input map and want to share it, you can upload it to the
Input Maps category of the repo.
