Sorry for the top post. 

You could put it in onedrive or Google drive or box and share a public link‎? You could also upload it to a github repo..

I could if I knew where to upload a 4MB binary file.

I got into the UART and there is a "lua" command, but I couldn't get it to do anything. Giving it Lua code, filenames, gibberish, just no result at all. I suspect the Lua support is just an option that this particular firmware doesn't have.

These chips are also used in cheap/knockoff video games (notably the Vii), so maybe it works there?
