Using BSP D3 with EmulatorJS on KhoGameHub

The BSP D3 works with all games in the KhoGameHub library through EmulatorJS. Here's how to get the best experience:

• On PC: Pair in Xbox Mode via Bluetooth before opening your browser. EmulatorJS detects it automatically on page load.
• On Android: Use Standard Android Mode (X + Power). Open Chrome, navigate to your game, and the controller activates when the emulator loads.
• On iPhone/iPad: Connect in MFi Mode first, then open Safari and launch your game. Tap the screen once to give the emulator focus before using the controller.
• Button mapping: Go to the gamepad icon in the EmulatorJS toolbar to remap any button if the default layout doesn't match your preference.

🎮 Tested on KhoGameHub: BSP D3 works seamlessly across NES, SNES, GBA, PS1, and NDS titles. For PS1 games, Xbox Mode on Android delivers the lowest input latency.
