Yeah sure thing. This is what is in the Asset Preparation Tab.
Assets Password is just 'abc123' for testing.
Using imgur because embedding pictures is giving me an error.
Interestingly, this did not fix the issue I was having, however I did find the culprit after some a lot of testing with new projects, and different settings of RMCookTool.
With RMCookTool, you can go to Utilities > Edit Metadata > Essential Information and Presentation, and there is an option to input the 'Game ID', in my case, if it is named ANYTHING that is not 'rmmz-game' it will break the linking paths and cause the whole main.js is missing error.
It seems like this field is fine to leave as default, as when I leave it untouched, the game will launch and function just fine.
