It is important to distinguish keys.dat from official engine files used by Vice City:

Feature Name: Customizable Controls Revamp

Where is keys.dat located?

• Original retail / Steam version (pre-DE):
  C:\Users\[YourUsername]\Documents\GTA Vice City User Files\

• Rockstar Launcher version:
  Same Documents folder path.

• Definitive Edition (2021):
  Does not use keys.dat; controls are saved in cloud/profile data.

4. File format and structure

• Variants exist: plain-text key=value entries or short binary tokens.
• Common plain-text entries:
  • executable path or name
  • resource identifiers
  • simple numeric flags
• When binary, entries are short fixed-length records; reverse-engineering requires a hex editor and pattern-matching against known vanilla files.

5. Forensic & Modding Relevance

• Cheat detection: None. keys.dat is not used by anti-cheat (no multiplayer in vanilla VC). Mods like Vice City Multiplayer (VCMP) ignore it entirely.
• Forensic timeline: Modification timestamp of keys.dat indicates when a user last changed key bindings – useful for reconstructing user activity on a shared machine.
• Modding: Custom control schemes can be distributed by sharing a keys.dat file (e.g., “WASD to arrow keys” mod). Tools like VC Control ReMapper decode/encode the binary structure.

Alternative Methods

Some players prefer using in-game options or third-party software to manage their controls, as these methods can be more user-friendly and don't risk corrupting game files.

Scenario 4: Gamepad/Joystick Conflicts

Vice City’s joystick detection is primitive. If your USB gamepad is jittery, the game might ignore the keyboard entirely. The keys.dat stores deadzone and axis inversion settings. Deleting or resetting keys.dat (and the .set file) often resolves phantom inputs.

3. I deleted keys.dat — will my game break?

• No. The game generates a new default one automatically on next launch.
