VAPlayer is an x86_64 system emulator for Android virtualisation, built on a pruned QEMU source tree.

• core/ — trimmed QEMU tree (upstream qemu.git) used to build the vaplayer-core binary.
• ui/ — Qt 6 desktop front-end that drives vaplayer-core over QMP. The sidebar exposes V-Flash (inspect / flash an image) and ROM Manager (download, prepare, and inject the ARM bridge). See ui/README.md.
• tools/ — provisioning tools: fetch and unpack a base Android image, inject ARM translation, and flash images offline. See tools/README.md.
• COPYING, COPYING.LIB — GPLv3 / LGPLv2 licenses inherited from QEMU.

The core/ tree is reduced to what x86_64 system emulation needs:

• Only the x86_64-softmmu target (target/i386) is kept.
• Legacy guest architectures (arm, mips, riscv, ppc, sparc, s390x, hppa, loongarch, hexagon, ...) and their devices are removed.
• docs/ and tests/ are removed; unused subprojects and legacy devices (floppy, IDE, SCSI, legacy NICs) are pruned.
• Firmware blobs in pc-bios/ are limited to the x86_64 set.

VirtIO drivers retained: virtio-gpu, virtio-blk, virtio-net, virtio-snd, virtio-input.

The result is build/vaplayer-core. Hardware acceleration is provided by WHPX (Windows), KVM (Linux) and HVF (macOS), with TCG as the portable fallback.
