awesome work! I have been trying to build something similar and originally built a basic prototype in pure JS and then converted to a react library but it became apparent that due to the extra performance cycles that it needs to be rewritten into wasm for the performance I want. I had a similar idea, community driven content and interchangeable packages for games and protocol specs around a common format that allows for scripting and assets to be simply loaded and changed much like a cartridge. glad to see others working on a similar idea! good luck!
