How to make Breakout 4K?

[Zach]

When I was hacking Combat, I expanded it to 4K simply by adding the following lines at the end:

 

ORG $FFFC

.word $f000

.word $0000

 

Unfortunately, it isn't working for Breakout. I can produce a 4K file, but Z26 displays it as garbage. I also tried replacing $f000 and $0000 with the last four bytes of the original Breakout, without success.

 

Any idea what's going on?

Breakout uses the BRK vector to position players so it can't be set to $0. Add this to the end of the file...

   org $FFFC

   .word $F237

   .word $F1C6

Thanks Dennis! Your code did the trick. I'll do my homework to understand the BRK interrupt more, since it never came up in Combat.

 

By the way, I've been having fun with my recently acquired Climber 5.
