📝 Walkthrough

Walkthrough

The changes replace an assembly-based trampoline mechanism in hooks/xact_3dapply.cpp with a hook-based approach. A new function fix__XACTApplyFailed is introduced in section/xact_3d_fix.cpp to handle XACT apply failures with one-time warning logic, removing complex inline assembly code.

Changes

Cohort / File(s)	Summary
Assembly Trampoline Removal hooks/xact_3dapply.cpp	Removed inline assembly trampoline that created a jump/thunk entry to xact_3d_apply.
Hook Configuration hooks/xact_3dapply.hook	Added new hook entry at address 0x004D9B21 that calls fix__XACTApplyFailed.
XACT Apply Handler Refactor section/xact_3d_fix.cpp	Replaced assembly-heavy xact_3d_apply() with simplified fix__XACTApplyFailed() function that performs one-time warning using static flag instead of inline assembly control flow.

Poem

Assembly trampolines fade away! 🐰
Hooks and warnings save the day,
XACT now whispers soft and clear,
One-time notice, never fear!
