Ok this is going to require an extra two menu lines since I want to 
finalize one version of the game.  How do you run other CoCo games for DOS?
I might just use 5) and 6) options in the main title screen to toggle 
those modes.  Anything else required besides just setting the GIME bit?
And if I'm right 50hz is slower, right?  :)
