Sampfuncs 037 R5 🔥 Must Read

If the game crashes on startup, remove Sampfuncs immediately — it’s conflicting with another mod.


The SA:MP client has gone through several versions (0.3c, 0.3e, 0.3z, and finally 0.3.7). Each update introduced anti-cheat mechanisms and structural changes. As a result, the developers behind SAMPFUNCS had to release specific builds to restore functionality.

SAMPFUNCS 0.3.7 R5 is the fifth revision built specifically for SA:MP version 0.3.7.

Why does "R5" matter? Early revisions of SAMPFUNCS for 0.3.7 had stability issues, memory leaks, and compatibility gaps with the RakNet protocol (the networking library SA:MP uses). The R5 revision stabilized the hooking methods, reduced crashes related to vehicle sync, and introduced better support for high-resolution displays in the chat overlay.

SAMPFUNCS is a tool. In the wrong hands, it can be used for cheating (like aimbots or vehicle surf). Most roleplay servers (LS-RP, Eclipse, etc.) will ban you for having SAMPFUNCS installed because it allows "injected" movements.

Always check your server’s rules before launching the game with this .asi file.

Install the CLEO 4 library into your GTA San Andreas root folder.

Place the SAMPFUNCS.asi file into the main GTA San Andreas directory.

On the first run, it will automatically create a SAMPFUNCS folder for settings and plugins.

Troubleshooting: If the plugin fails to execute, try running both your GTA San Andreas and SA-MP launcher as an Administrator. Why use it?
