Have uploaded, but I couldn't work out how to upload a version to be playable in the browser (like NoTimeToPlay's ones).

Am I missing something simple?

Hi 

Yes, you can use jsspeccy.org emulator and link it to your file. (IN xxx port command doesn't seem to work here)

Also torinak.com/qaop/ does this too...  (IN xxx works)
