KytyPlus v4.6 is released. KytyPlus is a KytyPS5-based PlayStation 5 emulator for Windows, macOS, and Linux. This repository is a standalone project derived from KytyPS5 (itself based on Kyty), with additional work focused on iGPU optimization, build stability, and a unified PS4/PS5 dispatch (iGPU behavior is not yet verified; see iGPU status).

KytyPlus Changelog:
Games can now be launched straight out of a .zar archive, and a class of shader-descriptor
aborts no longer kills the game.
ZArchive (.zar) loading, without extraction
Load Game gained a "ZArchive game image (.zar)..." option. The archive is read in place:
members are decompressed on demand through the emulator's archive!/member path namespace, so
nothing is extracted, staged or copied to disk. The archive reader, the file layer and the guest
/app0 mount already supported this — what was missing was --game routing and a launcher
entry point.
.zar files inside a configured game folder now appear in the list like .ffpfsc and
.exfat images do, and Explorer's "Open with" and --open-image accept them.
The mount-progress dialog no longer waits on an archive. That dialog is driven by markers
printed by the external NAPS helper, which an in-process archive never emits; sharing one
predicate between the two would have left it spinning forever on a .zar. Formats that need the
helper are now tested separately from formats that merely launch.
A .zar with no eboot.bin says so instead of failing later as an unclear missing-file
error.
Crash fixes
An unmapped shader buffer descriptor is now treated as unbound. A descriptor whose base
address is not committed at all went through a clamp that reports a fatal error and aborts.
Titles can legitimately hold a descriptor pointing into freed memory and never bind it to a
shader stage; that now degrades to the same empty binding an explicitly-zero address already
produced, with a capped log line. This is what killed Demon's Souls (PPSA01341, issues #16 and
#17) before its intro cutscene — on Windows and on Fedora alike.
Compatibility table
Astro Bot (PPSA21567) is now listed, at Ingame (broken).
Known issues
The .zar path was verified against archives built for the purpose, not against a real game
.zar; none was available to test with. The mechanism is exercised end-to-end, a shipped title
in that container is not.
The Demon's Souls fix has not been run against a dump locally — it rests on the reports in #16
and #17.
Astro Bot reaches in game but is still not playable: frame rate is far from real-time on an
iGPU, and the title can still exit on its own during a session.
