This report documents the nature, compatibility, and technical considerations of a save game file generated from Version 1.01 of Grand Theft Auto: San Andreas. Version 1.01 is a specific patch release primarily associated with the PC version of the game (post-Hot Coffee removal) and certain digital re-releases. Save files from this version are not backward compatible with the original v1.00 or v1.03 (Steam/Modern) without modification.
Most classic editors (like Paul B, Nudel, or Ryder editors) were built for v 1.0. If you open a v 1.01 save, you might see gibberish stats. gta san andreas v 1.01 save game
The only reliable editor for v 1.01 is:
Do not edit: The "Mission Passed" counter manually in a hex editor for v 1.01. The offset values shifted by 12 bytes compared to v 1.0. Do not edit: The "Mission Passed" counter manually
To understand the v1.01 save, one must first understand the original v1.0 release of San Andreas. The launch version was infamous for its glitches and game-breaking bugs. Missions would fail to trigger, unique vehicles would disappear from garages, and perhaps most notoriously, the “Doberman” mission’s marker would occasionally fail to appear, locking players in Los Santos forever. The most feared bug, however, involved the Supply Lines mission—controlling a notoriously fragile toy plane with fuel that drained unrealistically fast. On v1.0, many players found the mission literally impossible, forcing them to abandon hours of progress. To understand the v1
The v1.01 patch (released shortly after launch for PC, and later reflected in console reprints) was Rockstar’s apology in code form. It fixed the fuel consumption, stabilized mission triggers, and patched the garage glitches. But the patch presented a cruel problem: save files created in v1.0 were often incompatible or unstable when loaded in v1.01. Thus, the v1.01 save game was born—not as a choice, but as a necessity.
Let’s be honest. Even with v1.01’s smoother aiming, "Wrong Side of the Tracks" (where you chase the train with Big Smoke) is notoriously inconsistent. Many players download a save game that starts immediately after this mission to preserve their sanity.
