New Features

  • Multi-plateform build: AMD64, I386, ARM64, ARMv7, ARMv7a, ARMv6, ARMv5, RISC-V 32/64, PPC64le, Mips, Windows 32/64, Android (Exec only), m68k... Thanks dockcross and crosstool-ng
  • Add Qt GUI (Qt 6.6.0 and Qt Quick)
  • Add CUDA support (tested with NVIDIA RTX 2070 and 3070)

Usage (GUI)

./GTA_SA_cheat_finder

Usage (CLI)

./GTA_SA_cheat_finder --min 0 --max 60000000 # (Searches codes from index 0 to 60000000, from A to: BYKYLXA alphabetic sequence)
./GTA_SA_cheat_finder --min 50 --max 58800000 # (Searches codes from index 50 to 58800000, from XA to: LFLQXD Alphabetic sequence)
./GTA_SA_cheat_finder -h # Get help (or with --help)

Example

./GTA_SA_cheat_finder --min 0 --max 600000000

You should get this result:

Number of calculations: 600000000

From: A to: BYKYLXA Alphabetic sequence

Benchmark

CPU

On AMD R7 5800H (clang 16)

5429503678976 = ~4h
208827064576 = ~8 min
8031810176 = ~20 min
1544578880 = ~3 sec
308915776 = 0.6 sec

GPU

On NVIDIA RTX 3070 (clang 16 and CUDA 11.3)

5429503678976 = ~45min
208827064576 = ~1 min
8031810176 = ~2 sec
1544578880 = ~0.3 sec
308915776 = 0.06 sec

How does it work ?

  • The algorithm will generate sequences of characters (A, B, C... AA, AB, AC...)
  • It will then calculate hash (JAMCRC) from series of characters
  • It will compare hashes, if they are equal to one of the hashes of one of the official cheat codes, this will save the sequence of characters
  • When it is finished it displays the results and each code found can work as a alternative cheat code for GTA SA
