QEMU ESP32 Libraries (auto-built)

These prebuilts have moved.

Velxio's QEMU shared libraries (libqemu-xtensa, libqemu-riscv32) and ESP32 boot ROMs now ship from the velxio.dev license module instead of this GitHub release.

Or build QEMU yourself

The full source-build guide lives at docs/BUILD-QEMU.md. Compile lcgamboa/qemu once (15-30 min on a laptop), drop the .so files in, no key required. AGPLv3, freely buildable.

Why?

The prebuilts were being scraped by automated tools — including some that repackaged them commercially. Routing through a free key gates that pattern without changing the AGPLv3 promise. Velxio source is unchanged. Anyone can rebuild from lcgamboa/qemu. This is just where the convenience binaries live.
