Title

MihawkOS (PPSA99170)

Content version tested

5.0.0-alpha-5 (catalog release), homebrew.

AnyPS5 commit

main at 76fd1c09e9, and separately the head of #12826 (f2df214461, rebased on 91a69952c1) with a local junction for /mnt/sandbox/PPSA99170_000/app0 and a local sysctl probe.

System tested

Windows 11, AMD Ryzen 5 5600, AMD Radeon RX 6800 XT, WinLibs GCC 15.2.0 r7, Release.

Furthest point

Its launcher UI at about 60 fps, with the workarounds listed under Current blocker; not gameplay.

What is shown

With #12826 applied and /mnt/sandbox/PPSA99170_000/app0 pointed at the title's app0 by a local junction, the title starts and draws its launcher: MihawkOS | FPS: 59.99 (788), the theme list (30 entries), audio open at 48 kHz stereo, its web UI reported on port 6767 and the wallpaper at 3840x2160. Its own log then reports that a game cannot start because the Wine runtime is not installed in /data/ps5proton/runtime/ge11-7, and it stops at its payload check (elfldr, Kstuff, ShadowMountPlus, websrv absent).

Current blocker

1. On plain main it does not load: it imports fNoviuIwykc (sceKernelAllocateDirectMemoryForApp) and cBp0Ad-24LA (sceKernelProtectDirectMemoryForPID) from libkernel.prx, and both are declared only in libkernel_sys.prx, so the loader stops on an unresolved ELF import. Open PR: feat(libkernel): export sceKernelAllocateDirectMemoryForApp and sceKernelProtectDirectMemoryForPID #12826.
2. sceKernelGetProcessAbiType is a stub that throws. Open PR: feat(libkernel): implement sceKernelGetProcessAbiType #11939.
3. It reads sysctl {1, 14, 8, 0} (kern.proc.proc) while it starts, and the runtime throws on the unsupported MIB, which aborts the title: sysctl_nid_postfix: unsupported MIB 1.14.8.0. PR: feat(libkernel): answer kern.proc.proc with the calling process #13532.
4. It opens /mnt/sandbox/PPSA99170_000/app0/assets/ directly, which the runtime does not resolve; without the junction it exits with Could not find asset path in "/mnt/sandbox/PPSA99170_000/app0/assets/". No PR yet.
5. Its launcher needs console payloads (an ELF loader on port 9021, Kstuff, ShadowMountPlus, its websrv on 127.0.0.1:8686) and a Wine runtime under /data/ps5proton, so the launcher UI is as far as it gets here.

How it was run

tools/audit_dump.py with rel-main at 76fd1c09e9 reported 592 implemented, 7 partial and 3 stubs (sceSystemServiceGetLocalProcessStatusList, sceKernelGetProcessAbiType, sceKernelProtectDirectMemoryForPID), 0 absent. The run is rel-main's app.exe for 30 s with APS5_PAD_INPUT_FILE set; the evidence is the title's own download0/hui/dev/app.log and run.err.

AI-assisted: yes

[relativespace2K]

Update: #13532 is merged (41d0d902cc), so sysctl {1, 14, 8, 0} (kern.proc.proc) no longer aborts the title at unsupported MIB 1.14.8.0.

What the title still needs before it can load:

1. feat(libkernel): export sceKernelAllocateDirectMemoryForApp and sceKernelProtectDirectMemoryForPID #12826 - sceKernelAllocateDirectMemoryForApp and sceKernelProtectDirectMemoryForPID exported from libkernel.prx (open).
2. feat(libkernel): implement sceKernelGetProcessAbiType #11939 - sceKernelGetProcessAbiType (open).
3. A /mnt/sandbox/PPSA99170_000/app0 path alias, which no PR covers yet; without it the launcher exits with Could not find asset path in "/mnt/sandbox/PPSA99170_000/app0/assets/".

Once it loads, the launcher still needs console payloads (an ELF loader on port 9021, Kstuff, ShadowMountPlus, its websrv on 127.0.0.1:8686) and a Wine runtime under /data/ps5proton.
