This is a minimap lua script for a GBA game called Rebelstar - Tactical Command. The script is useful for observing hidden enemy units. I'm not a coder, so this can be improved a lot. (For easier testing, start Skirmish Game instead of New Campaign.)

while true do
vba.registerbefore( function ()

Nice idea! You can compress this script quite a lot by using a for loop. It would look something like this:

while true do
vba.registerbefore( function () 

startx = 0x0200f441

for k=0,22,1 do

x=memory.readbyte(72*k+startx)
h=memory.readbyte(72*k+startx+4)
t=memory.readbyte(72*k+startx+15)
h=memory.readbyte(72*k+startx+19)

if (t ~= 0) then gui.pixel(x, y, "red") end
if (t == 0) then gui.pixel(x, y, "green") end
if (h == 0) then gui.pixel(x, y, "grey") end

end

end)
  vba.frameadvance()
end

Tack ska du ha, Randil! The script is easier to manage now. :) What I would also like to have is making the enemies always visible (not only in the minimap). It can be done by changing the visibility value of all units:

memory.writebyte(72*k+startx+11, 1)

The problem is that when the enemies are visible, the game behaves differently (causing desyncs). I suppose one possibility would be to run this part of the script in a "parallel game", use gui.gdscreenshot and then paste it on top of the original game screen with 50% opacity. But it's a bit too complicated for me at the moment.
