How to handle large filter options

I'm working on a gaming website project where users go through large amounts of data and search results. on a search page users can filter through historical platforms. The problem is that there are over 120 platforms and the vast majority of them are 'legacy' and could be irrelevant to the majority of users.

Is hiding all the legacy options considered bad practice? And if not what could be a good approach, maybe behind a search box?

Thanks!
