PCEE2 v0.1.0

First release of PCEE2 — a libretro core port of current PCSX2 (v2.7.x).

Installation

Copy the core + pcee2_libretro.info into your RetroArch cores directory — that's it, the cores are statically linked:

• Linux x86_64: pcee2_libretro.so
• Linux aarch64 (ARM64) — two dynarec generations, pick one (see below):
  • ...-aarch64-isztl-static.zip — recommended, newer ARM64 dynarec, SDL3 statically linked / self-contained
  • ...-aarch64-isztl.zip — newer ARM64 dynarec, needs system libSDL3.so.0
  • ...-aarch64-static.zip — original (ARMSX2-based) dynarec, self-contained
  • ...-aarch64.zip — original (ARMSX2-based) dynarec, needs system libSDL3.so.0
• Windows x64: pcee2_libretro.dll (requires the VC++ 2015–2022 x64 redistributable)
• macOS x86_64 / Apple Silicon via Rosetta 2: pcee2_libretro.dylib + libMoltenVK.dylib (both into cores), then clear quarantine once: xattr -cr ~/Library/Application\ Support/RetroArch/cores

Then put a PS2 BIOS into <system>/pcsx2/bios/ and the PCSX2 resources directory into <system>/pcsx2/resources/ — see the README.

Which aarch64 build?

• -isztl builds use the actively-maintained ARM64 EE/IOP/microVU dynarec from isztldav/pcsx2 on top of the same current PCSX2 base as this core (branch libretro-arm64). This is the newer, preferred generation.
• The plain (non-isztl) builds are the original ARMSX2-based dynarec, kept here for comparison.
• Prefer a -static zip unless your distro already ships libSDL3.so.0.

Highlights

• Current PCSX2 emulation core (v2.7.393 base)
• Vulkan / OpenGL / Software renderers, 1x–4x internal resolution
• Savestates, RetroAchievements, multitap (8 players), GunCon 2 lightgun, rumble
• 20+ core options incl. widescreen patches, speed hacks, analog response
• ~10–34 % faster than LRPS2 at identical settings

Linux x86_64 is tested; Windows, macOS and all Linux aarch64 builds compile but are untested — feedback welcome. The aarch64 builds are an early preview (Raspberry Pi 5 / RK3588-class hardware recommended).
