Hulabee Sauce engine: reconstructing a game VM and asset formats

hulabee reconstructs the Sauce engine used by Hulabee Entertainment games as an SDL2 virtual machine. It includes opcode tracing, tools for extracting and converting .pan and .gg assets, and notes on the engine's language and file formats. The VM documentation names Moop and Dreadly in the Treasure on Bing Bong Island and Ollo in the Sunny Valley Fair as supported games.
