I see from a Google search that there was some desire amongst Mac users to run jzIntv, but the command line interface was very intimidating.
I have been thinking of creating a quick launcher in AppleScript that would be easier to use. You would place the launcher in the same folder as the jzIntv program and the EXEC.BIN and GROM.BIN files (obtained from the Intellivision Lives! and Intellivision Rocks! discs released by Intellivision Productions), start the launcher, tell it what game file you want to play, and away you go!
However, I have a question.
Normally, jzIntv maps the alt/option key to the lower-left action button, and the ctrl button to the lower-right button. After some discussion, I believe this had the *right* set of alt/option and ctrl keys in mind.
I use a MacBook Pro, which only has the left set of ctrl and option. Thus the opposite mapping (ctrl=>left action, option=> right action) is more convenient.
I want to allow users to remap the keys. AppleScript only allows a limited interface, but I think I have a solution. I will provide a mapping that is MacBook friendly. To use it, simply create a copy of it named "jzIntv mapping" in the same folder as the launcher. To go back to normal, delete "jzIntv mapping". And, if you're feeling adventurous, read the jzIntv documentation, and modify "jzIntv mapping" yourself.
Does this sound good?
