By "3rd party", we mean any plugin not written by Jabo, Azimer, Icepir8 or Zilmar.

Project64 Legacy uses an open plugin specification. This means that other people are free to write compatible plugins, which you might like to use in Project64 instead of the ones provided. These may be available standalone or taken from another emulator package - visit some quality websites or use a search engine.

You should first check that the plugin is to the Project64 specification (sometimes referred to as "Zilmar spec.") and to the correct version of the specification. Consult the plugin or emulator documentation if you are not sure.

Project64 Legacy is backwards compatible with all public versions of the specification up the date of its release. (It was not made forwards compatible because there is no way of knowing in advance how the specification might change).

If you attempt to install a plugin that is not to a suitable specification then it should not show up in the menus in Project64 Legacy.

Extract the plugin (file ending .dll) and any support files it requires to the root of your Project64 Legacy plugin folder (by default, "\Plugin\" subfolder of your PJ64 Legacy folder). Start PJ64 Legacy, go to Options > Settings > Plugins and select the new plugin from the appropriate list and press OK. If the plugin initialises (starts) correctly there will be no error message. Remember, if you are using third party plugins the standard Project64 Legacy compatibility lists and notes may no longer apply to you.

If you have problems with a plugin, please consult the appropriate author or group. The Project64 Legacy team is not in any way responsible for the performance of 3rd party plugins! Nor can we gaurantee the peformance of the application while using 3rd party plugins.
