14qjrv080190, I inspected the assembly of the simulator.exe (i actually use ghidra) i successfully cracked the simulator.exe but, it seems to have some problems with the NFCLIB.dll, i searched into it and i found some auto-checks (Check, CheckOutFeatureNow, CheckOutModelNow, CheckOutNeptuneNow) i tried to crack it but, at least the crack works, libraries wont load... i dont understand why but it seems to have problems with "simmgr" notably with a module named "unitscheduler". i think there is some "check" or verifications on control.exe and others in simulator.exe but i actually didnt succeed to locate them and patch them... i will keep you informated but the work is advancing ! maybe i failed with some RET of JMP... sorry for my bad english
I used "reverse engineer anything" and ChatGPT 6.1 Astra to crack the executable and so far it's worked. Two locations within that file were changed: 0x3360 Replaced a 16-byte span at the local-license validation function entry with a success return and its expected integrity-state update. 0xDD6F8 Cleared the obsolete 2-byte relocation entry for the replaced instructions, preventing ASLR from corrupting them. 17 bytes differ overall across those two spans. Instead of linking the patched executable I attached a script that can apply the patch for you using Powershell, run as Administrator. I uploaded 2 patches, 1 for just the .exe file and 1 to also patch some missing reg keys to get the CCTV working.
