Customization is one of the pillars of accessibility in gaming, so it's reasonable to expect that you should be able to decide the mapping of your controller buttons. However, not every game allows you this opportunity within its settings, seemingly leaving you stuck with whatever control scheme the developers thought you should use. Luckily, Microsoft has ensured that you can fully remap your Xbox controller on a system level, eliminating this issue almost entirely. Here's how to remap your Xbox controller buttons on Xbox consoles, including the Series X and S.
