/!\ Use the ParallelN64 emulator available on Parallel Launcher for better compatibility and playability.

/!\ If you are using the Project64 emulator, the game needs the expansion pack to work, don't forget to enable it:

In Project64, click on "Options" then "Settings" in the "Options" tab, you need to uncheck the "Hide advanced settings" box. Then you need to go back to the settings, there will be many more tabs, click on "ROM Settings", and set the RDRAM size to 8MB.
