Troubleshoot VU Files

Common Problems Opening VU Files

PlayStation 2 is Not Installed

You attempt to load your VU file and get an error such as "%%os%% Can't Open The VU File Extension". When this happens, it is commonly due to PlayStation 2 missing in %%os%%. This will prevent you from double-clicking to open the VU file because the OS doesn’t know how to handle it.

Tip: Another VU-related program can be selected to open the file by clicking "Show Apps" and finding the application.

Incorrect PlayStation 2 Version

It is possible that your version of PlayStation 2 isn't able to open your Playstation 2 VU Development Source Code file due to incompatibility. Installing the latest version of PlayStation 2 from Sony is recommended. This problem is predominately due to having a Playstation 2 VU Development Source Code file version that was created by a newer version of PlayStation 2 than what you have installed on your PC.

Tip: If you right-click on your VU file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.

Summary: In either case, the majority of problems opening VU files are related to not having the correct software application installed on your computer.
