What is "Commando 2084"?
It is like Commando, but with the Robotron 2084 controls. Changes made to the original Commando:

Controls are like in Robotron 2084. Use two joysicks, or better yet, one Unijoysticle 2 to control the hero:
Joystick #2 to control the hero direction
Joystick #1 to control the fire direction
Autofire is enabled
'Space' to throw grenades.
Levels 2 and 3 have bosses (enemies taken from Robotron 2084)
The SFX used when these bossed are killed, are unused SFX from the original Commando.
Difficulty increased, otherwise the game would be too easy to play:
No extra lives
28 soldiers are inside forts, instead of 20
Flickers were reduced, but there are still a few. Changes made to reduce flickering:
Uses double-buffer multiplexer
Faster sorting algorithm
Faster "view port" rendering
Music is played outside IRQ
Unrolled some functions like "apply delta"
And other tiny improvements here and there
Smaller binary, single load
Removed unused data/code
Packed everything in a single binary
Compressed binary using exomizer
Misc fixes
