If you remove
- the tow-bar with the 2nd kernel,
- most of the levels,
- the text messages,
- the stars,
- the sound,
- the anti-flicker routines
- and a lot of features
use a more simple score display, etc. then...
...it still wouldn't fit into 4K!
Some reasons:
- due to the complexity and limitations of the kernel, the setup
routines are very large.
- the physics of the ship and the attached pod, cost a lot of space for
code and the needed tables
- Thrust requires x-positioning of up to nine objects. This would
require to much time without using a predefined table.
- running out of RAM requires some tricky and space consuming coding
You had to remove some very important parts of the gameplay to fit
Thrust (or whatever you could call it then) into 4K.
But it could fit into 8K without loosing to much.
Have fun!
