https://mqemulator.net/downloads.php - The MacroQuest Next (Beta) has all the major plugins HOWEVER most of them are not allowed to be used. I compiled my own version of MQ2 using the Red Guide Vanilla build because I wanted the camera plugin and do not really use it lol. I have unloaded most of the plugins to match what is in the original MQ2 build.
The E3 build of MQ2 has also be said to be allowed but you are still not allowed most the automation that you can do with it. I have stuck to the "No action is to take place unless you press a key". If you prefer to stick to the MQ2 version you have and want to get the macros working feel free to reach out to me. I can load up that version of MQ2 and tinker with the macros to fix them. MQ2 syntax has changed over the different versions and somethings work in the old one way and the new another. I had to rewrite some of my own macros due to this change.
