OpenRPF — Enhanced alternative to OpenIV.asi

OpenRPF is an alternative to OpenIV.asi used in GTA V Enhanced that replaces the discontinued OpenIV.asi. It works similarly to OpenIV.asi: allowing modified files to be loaded from the mods folder, thus avoiding modification of the game's original files.

**OpenRPF is a replacement for OpenIV.asi**, used in GTA V Enhanced (enhanced version) to replace the discontinued OpenIV.asi. It works similarly to OpenIV.asi: allowing modified files to be loaded from the `mods` folder, thus avoiding modification of the game's original files.

Function 🔧

• **OPEN compatible with encryption**

OpenRPF supports both game-native archives and archives created using OpenIV (OPEN). No need to re-encrypt modified files.

• **rpf.cache bypass under Gen9**

OpenRPF bypasses `rpf.cache` for modified files placed in the `mods` folder, allowing these files to be loaded without additional action.

• **Integrated ASI Loader**

Similar to the `dinput8.dll` provided by OpenIV, OpenRPF includes `dsound.dll` to enable ASI plugin loading in GTA V Enhanced (OpenRPF.asi can also be loaded).

• **Performance Optimization**

OpenIV.asi may cause performance degradation in file load management. OpenRPF solves these problems, resulting in a smoother gaming experience.

Installation 📦

• Extract the contents of the compressed package to the directory of GTA V Enhanced (that is, the folder where `GTA5_Enhanced.exe` is located).
• Create the `mods` folder.
• Place your modified RPF archive into the `mods` folder just like you did with OpenIV.asi.
• Launch the game and enjoy your mod in GTA V Enhanced.

Notes/Warnings ⚠️

• **mod does not change file versions**:

Using files from Gen8 (GTA V Legacy) directly on Gen9 (GTA V Enhanced) will cause the program to crash. Please make sure to use a GTA V Enhanced compatible file or convert it using the tools provided by Dexyfex in CodeWalker:

• **Some resources have not been perfectly converted by CodeWalker**:

This may cause crashes or visual anomalies. If you encounter problems, please report them on CodeWalker’s Discord:
