Parkour Mod for GTA San Andreas on PS2: Not Possible

You cannot install a Parkour mod on the PS2 version of GTA: San Andreas.

Why PS2 Modding Doesn't Support This

No User-Accessible File System: PS2 games run from pressed DVDs. You cannot inject scripts, models, or animations without a modchip + burned disc rebuild—or a PS2 with FreeMCBoot + ESR/OPL loading patched ISOs from HDD.
Complexity: Parkour requires new animations, collision detection, player-state logic, and input remapping. This needs CLEO (script hook) or ASI plugins—PC-only tools.
Memory Constraints: PS2 has 32 MB RAM. Custom animation sets + script VMs often exceed budget alongside base game.

PC Version (Steam / Original / Rockstar Launcher):
- Install CLEO 4 + Parkour Mod (e.g., "Parkour Mod v2.0" by Rusu or GTAForums community).
- Or use SA-MP / MTA:SA servers with parkour scripts (freerun, climb, vault).
Mobile Version (iOS/Android): Limited mod support; some CLEO ports exist but unstable.
GTA V (PC): Parkour Mod (by JulioNIB) — full mirror's edge mechanics, animations, config menu. Best experience.

Cheat Codes (Action Replay / AR Max / CodeBreaker): Can give super jump, moon gravity, infinite sprint—simulates some parkour feel.
Save File Edits: Max stats (stamina, muscle) for better climbing/vaulting in vanilla game.

For real parkour: Play on PC. The PS2 hardware/software stack cannot support it.
