Orbital
Virtualization-based PlayStation 4 emulator.

Roadmap
‧ Boot kernel.
‧ Kernel debugging with symbols.
‧ Support for Orbis kernels with KASLR.
‧ Emulating Aeolia's UART device (partial).
‧ Successful driver initialization.
‧ Fix Starsha DCE initialization.
‧ Adding Vulkan support to QEMU.
‧ Process Starsha FIFO commands with a Vulkan backend.
‧ ...

Remarks
‧Until keys are dump, decryption with SAMU will be "emulated" by
  hashing encrypted input blobs and returning decrypted blobs previously
  obtained from the actual console.
‧Kernel ELFs generated from memory dumps will not work since R/W segments
  might have been modified into a state where booting is not possible. Please
  generate proper binaries offline by decrypting ELF segments with SAMU, not by
  dumping memory.

Status
This is the current state of Orbital on publicly available kernels
along with the date in which the tests were made:
‧0.82 (2017-11-29): Will run fine until hrtimer initialization and then
  crash.
‧4.55 (2017-12-21): (Needs testing).
‧5.00 (2017-12-21): All drivers initialize correctly. Later during system
  initialization, the kernel gets stuck at an endless loops during
  dce_flip_init.

推 kenryu: 網站
推 emulators: 真的假的? 新規參戰喔?
推 Cassious: 配備要多高才跑得動PS4模擬器
推 srwcc: 真假XD推
→ srwcc: 所以xbox應該非常難模擬...
推 rockmanx52: XBOX系列不是難 是寫了就會被阿三找去喝茶
推 qazxswptt: 微軟這點很不好 自己的XBOX相容作到一半就放著生灰
→ qazxswptt: 不如先半閉眼等有人寫出成果再請他去喝茶未來可當VC賣
推 wenen: PS4、Xbox One都是x86，模擬應該不難。這邊PS4都用虛擬機器
→ wenen: 來做了，主要的難度是保護機制吧
