A sweep of the 281 libSceHmd2 exports on a PS5 (firmware 13.60), each
called from a payload before sceHmd2Initialize once with every argument
null and once with every argument pointing at a zeroed 16 KiB buffer,
found 127 that answer the same code both ways and write nothing. 125 of
them are bound here, by NID, to one handler per answer: 45 return 0, 16
return 0x8a720008, 15 return 0x8a720004, 12 return -1, 10 reprojection
exports return 0x8a72000b, 9 return 0x8a720002, 9 return 0x8a720009, 5
return 0x8a721002 and one each returns 0x8a72002c, 0x8a721003, 0x400 and
0x20000. Each handler returns its measured value while the library is not
initialized and throws if sceHmd2Initialize ever succeeds, because the
initialized behaviour is not measured; since b378541e79 it fails with
UnsupportedFeature here, so these are the answers titles get.
Left out: the export that returns a pointer-like value, the one answering
0x8a72000a (which sceHmd2Initialize also returns for some applications),
the exports that answer differently to null and to zeroed arguments or
write output, the 16 that crashed the probe, and the exports that main,
its aerolib name where one exists.
