The current selected mission is only shown prior to the game starting.
Its sort of a splash screen that is displayed briefly. In attract mode
when you press p2-start the splash screen is displayed with the
current mission. Pressing p2-start again (and again) cycles through
the missions. Once you start a game or after a certain amount of
time the splash screen goes away. If you change missions during
the game you will not know which mission is active unless you keep
track of the order as you press p2-start. Because LL is maxed out
on how many vectors it displays during gameplay, adding any type
of extra display indicators, letters etc to the gameplay screen could
affect timing, cause flicker and possible gameplay timing differences.
So I chose not to alter the gameplay screen at all. I did make
some improvements to freeplay and added the splash screen above.

under the "Lunar Lander Mission Lamps" section.
Note this page is under construction and will be changing frequently
before this project is complete.
No plans right now for driving mission lamps as that would require
additional hardware, should there be a redesign someday I might
consider adding some outputs to the kit for that purpose. Right
now I dont have any available outputs on this design.
