This library and command-line tools implement a save-data patch engine that supports Save Wizard/Game Genie codes and Bruteforce Save Data scripts.

The library is cross-platform and is required to build:

• Apollo Save Tool PS2
• Apollo Save Tool PS3
• Apollo Save Tool PS4
• Apollo Save Tool PSP
• Apollo Save Tool PS Vita

• Save Wizard / Game Genie
• Bruteforce Save Data scripts

• Code Type 0: Standard 1 Byte Write
• Code Type 1: Standard 2 Byte Write
• Code Type 2: Standard 4 Byte Write
• Code Type 3: Increase / Decrease Write
• Code Type 4: Multi-Write (Repeater)
• Code Type 5: Copy and Paste
• Code Type 6: Special Mega-code
• Code Type 7: No More / No Less than Write
• Code Type 8: Forward Byte Search (Set Pointer)
• Code Type 9: Pointer Manipulator: (Set/Move Pointer)
• Code Type A: Mass Write
• Code Type B: Backward Byte Search (Set Pointer)
• Code Type C: Address Byte Search (Set Pointer)
• Code Type D: 2 Byte Test Commands (Code Skipper)

• Commands: set, write, search, insert, delete, copy, decrypt, encrypt, endian_swap, compress, decompress
• Hashes: crc16, crc32, crc32big, crc64_iso, crc64_ecma, md2, md4, md5, md5_xor, sha1, sha256, sha384, sha512, hmac_sha1, sha1_xor64, adler16, adler32, checksum32, sdbm, fnv1, add, wadd, dwadd, qwadd, wadd_le, dwadd_le, wsub, force_crc32, murmur3_32, jhash, jenkins_oaat, lookup3_little2, djb2
• Custom hashes: eachecksum, ffx_checksum, ff13_checksum, deadrising_checksum, kh25_checksum, khcom_checksum, mgs2_checksum, sw4_checksum, toz_checksum, tiara2_checksum, castlevania_checksum, rockstar_checksum, dbzxv2_checksum
• Encryption: aes_ecb, aes_cbc, aes_ctr, des_ecb, des3_cbc, blowfish_ecb, blowfish_cbc, camellia_ecb
• Custom encryption: diablo3, dw8xl, silent_hill3, nfs_undercover, ffxiii, borderlands3, mgs_pw, mgs_base64, mgs, mgs5_tpp, monster_hunter, rgg_studio

You can find .savepatch files for many PlayStation games in the apollo-patches repository.

Apollo command-line tools are useful for code creators and developers, to test SW codes and BSD scripts locally on a computer.

• dumper
• parser
• patcher
• patcher-bigendian

The parser command-line tool reads a .savepatch file, and provides a numbered list of detected cheat patches.

Apollo .savepatch parser v1.4.0 - (c) 2021-2025 by Bucanero

USAGE: ./parser file.savepatch [code #]

  file.savepatch: The cheat patch file to parse
  code #:         The code patch to display (Optional)

The patcher command-line tool reads a .savepatch file and a comma-separated list of patches, and apply the selected cheat codes to the target file.

Apollo cheat patcher v1.4.0 - (c) 2022-2025 by Bucanero

USAGE: ./patcher file.savepatch 1,2,7-10,18 [data-file.bin]

  file.savepatch: The cheat patch file to apply
  1,2,7-10,18:    The list of codes to apply
  data-file.bin:  The target file to patch

patcher-bigendian is provided to apply patches on PS3 (big-endian) save-game data files.

Apollo cheat patcher v0.6.0 PS3/big-endian - (c) 2022 by Bucanero

USAGE: ./patcher-bigendian file.savepatch 1,2,7,10,18 target.file

The dumper command-line tool reads a binary file and generates a .savepatch file with a SW code that writes the raw content of the binary data.

Apollo binary file SW dumper v1.4.0 - (c) 2023-2025 by Bucanero

USAGE: ./dumper filename.ext

Windows users that prefer a graphical interface can use Apollo GUI by SkillerCMP. The GUI uses Apollo CLI Tools to provide a user-friendly interface to apply save patches and scripts.
