v6.5.0 — Comprehensive CRC + TerminateGuard Fix

Root Cause (found via Ghidra binary analysis)

Denuvo has 3 independent CRC checker instances with their own vtables and function pointers. The trainer only bypassed instance #1. Instances #2 and #3 were still running integrity checks, detecting our patches, and reporting failures through 13 TerminateGuard call sites (only 1 was patched). The unpatched TerminateGuard sites called TerminateProcess successfully.

Also fixed: the TerminateGuard patch was NOPing the JZ (fall-through = call TerminateProcess) instead of changing it to JMP (always skip TerminateProcess).

Changes

• All 3 CRC instances patched — all function pointers now point to a XOR EAX,EAX; RET stub that returns 0 (success)
• All 13 TerminateGuard call sites patched — JZ changed to JMP at every location so TerminateProcess is always skipped
• CRC timer remains disabled — no thread suspension, no clean window
• RET stub returns 0 instead of garbage RAX value

How to use
