ps2emu

A PS2 emulator written from scratch in C++20. It needs no BIOS
dump: the EE and IOP kernels and the rom0 modules are emulated at
a high level.

Status    As of 2026-09-30, milestones M0 to M8 are done and M9
          (speed) is in progress. Of 30 retail games tested, 22
          reach a title screen or menu, 9 give the player control,
          and Disgaea plays 36,000 frames of scripted play with a
          save and a load. Regression target: Disgaea (SLUS-20666).

Speed     Not real time on the heavy games yet. Bench on a Ryzen 9
          9950X3D with the JIT and 6 GS threads, average fps:
          Disgaea 3D 74, Kingdom Hearts II 22, God of War II 9.
          The M9 goal is 59.94 average and 55 at the 1% low on
          God of War II and Kingdom Hearts II.

Requires  A game image: .iso, .bin/.cue or .chd. No BIOS. Game
          images are not supplied.

Usage     ps2emu play game.chd
          ps2emu run game.chd --frames 600

          play opens a window and is in the Windows build only.
          run is headless and is what the regression suite uses.
