JoyCheck Notes
JoyCheck Notes is the workshop log: short, technical writeups about diagnosing controller issues, modding stick modules, comparing Hall-effect vs potentiometer sticks, browser Gamepad API edge cases, and lessons from running a tool that has to work right the first time. New posts as they're written, no editorial calendar, no fluff.
