I think that it would be better to convert the code to the standard format,
as this would allow other things like diagonal moving bombs.

Couldn't the already existing destroy-the-shields routine be generalized for
use with bombs and player shots?

But Atari SI allows you to hit the invaders even when they're invisible.
This would be the difficult part.
