This release focuses on restoring original gameplay behavior, fixing input and New Game regressions, and hardening ZachFix's runtime patching infrastructure.

Highlights

Fixed New Game difficulty selection

  • Fixed the restored native Easy / Normal / Hard difficulty selector being skipped when starting a New Game without an existing save.
  • The native selector now works correctly on both the no-save path and the existing-save overwrite path.
  • Preserves the game's native per-save difficulty state.

Restored original Xbox combat strafe

  • Restored the original Xbox 360 combat-only LB/RB strafe ingress into the preserved PC movement states.
  • Preserves the original capability and player-state gating.
  • Requires Native XInput with the Xbox 360 input profile.
  • Disabled by default and available through Gamepad.RestoreCombatStrafe.

Input and controller fixes

  • Fixed several Native XInput ownership and input-mode transition issues.
  • Prevented Xbox 360 aim deadzone processing from leaking into mouse-look after switching back to keyboard/mouse.
  • Improved vibration state handling when changing input devices.
  • Fixed the analog vehicle-control trampoline to preserve the native x87 instruction sequence and FPU stack behavior.
  • Fixed F10 Reload/Apply handling for RestoreCombatStrafe.
  • Made the F10 vibration diagnostic non-blocking and safer across controller changes.

Runtime stability

  • Hardened MinHook rollback and residual-hook handling.
  • Added validation for the Direct3DCreate9 IAT target before applying known-build patches.
  • Improved validation for world-distance configuration values.
  • Fixed Additional DoF Blur resource handling across D3D9 device reset.
  • Improved screenshot comparison-state restoration and reporting.

Engine research and cleanup

  • Reconciled and expanded the reverse-engineered engine map.
  • Added detailed CEffect / CRdObjectEffect / XWP architecture documentation.
  • Cross-checked the fixed-effect timing path against the original Xbox 360 executable.
  • Removed retired experimental PhysX timing, vehicle cadence, solver telemetry, and player motor/brake runtime code.
  • ZachFix continues to leave native physics timing untouched while the remaining timing questions stay research-only.

Quick Turn and CEffect timing modification remain research-only and are not enabled in this release.
