The Löve game development framework packages games like this. The games are nominally Alia scripts but if you cat a zip file to the end of the Lua script the framework lets you access assets in that zip as if they were in the game's cwd. It's a cool abstraction, during development you can have assets just living on the file system and then "deploy" a flat file that accesses those assets the same way.
