For regular users, it really doesn't have much if any use. I'm developing it to assist with native development and reverse engineering firmware.

IIRC it could run the official firmware, but the biggest issue was the undocumented, proprietary touch chip. Kinda hard to pass the unlock widget on first boot without that, although very early alpha releases lacked it.

Indeed I did use qemuPrime as a reference for the keyboard driver. As for the touchscreen controller, fortunately the one on the G2 is documented, so that makes things significantly easier
