Optional GX presentation and guarded hardware paths alongside software rendering.
Wii controls
Wii Remote, Nunchuk and GameCube controller support.
Real PS2 BIOS

Source, verification notes and detailed technical checkpoints live in the repository.
04 — COMPATIBILITY
Compatibility is still experimental.
Gekko2 is not yet a general-purpose playable PS2 emulator. Current work prioritizes correct BIOS behavior, CPU/JIT precision and stable rendering before broad game compatibility.
