GameLoop Keyboard & Keymapping Not Working — Fix Guide

Keyboard keys not registering in GameLoop — despite being visible in the keymapping editor — is one of the most frustrating GameLoop issues. The symptom can appear as: keys that worked yesterday suddenly doing nothing, custom keymaps not applying when entering a game, the entire keyboard going dead while a game is in focus, or the keymapping editor itself failing to open. **Why it happens:** GameLoop's "Smart Keymapping" system intercepts keyboard input at a low level before it reaches the Android VM. If a Windows input hook, another application, an input conflict, or a GameLoop display setting breaks that intercept chain, keys stop reaching the game. The issue is almost always at the Windows ↔ GameLoop interface, not inside the game itself. **This is different from wrong key bindings.** If your keys are registering but do the wrong action, that's a keymap configuration issue (Fix S3). If keys don't register at all, start at Fix S1. | Symptom | Most likely cause | |---------|-------------------| | All keys dead only in GameLoop | Another app captured keyboard input (Fix S1) | | Keys work on main screen, dead in-game | Fullscreen input lock (Fix S2) | | Custom keymap not saved | Keymap not properly applied before entering game (Fix S3) | | Keymapping icon missing in-game | Smart Keymapping not supported for this game / compatibility mode (Fix S5) | | Only one key stops working | Windows shortcut conflict (Fix S4) | | Gaming keyboard macro keys not detected | HID vs RAW input mode (Fix S6) |
