I also started some game code. My idea was to load such data at 
runtime, not compile time.
I wanted a level file, that is just text and contains descriptions,
where to load what file.
So load enemy.spr at 0x4000, explosion.snd at 0x5000 etc etc.
That's slower than adding the data at compile time, but it
allows to reuse those files and it also allows easy modification
of the game. Just replace enemy.spr with a new version and your
done.

HTH,
Andreas
