Programming/Disassembly Help Wanted: Squish 'Em

[vdub_bobby]

I'm working on porting the A800 version of Squish 'Em to the 2600 and I was wondering if any of you fine A800 programmers could help me with the sounds - specifically, could someone with disassembly skillz (mad, preferably) point me to the sound data in the cart image; what values are put into the POKEY registers. I assume they update them once per frame, but if that isn't true I'd like to know that as well!

 

Thanks!

 

I'm also interested to know how they filled up 8K with this game...did the coder actually use all 8K?

Here we go! The whole Squish' Em is not 8kB but actually 4kB game (!!!) and it basically works as one really big VBI.

I am totally and completely not surprised!

 

As I convert it to the 2600 I was having a hard time seeing how it could possibly take up 4K. And the game hews so closely to 2600 specs that I'm not surprised that it's written like a 2600 game.

 

And thanks!

 

EDIT: Could someone tell me where the audio registers are?

 

EDIT II: Nevermind, found 'em: $D200-$D208

Just a quick note: I finished porting Squish 'Em to the 2600. Thanks again for the disassembly, I had a lot of fun commenting/labelling it.

I've got a few big 2600 projects in mind, I might also try doing something for the A800.

Squish'em is my top favorite little program for Atari 8 bit computers. Every time I play, i really enjoyed Squish'em.

 

It's great to hear a 2600 version will be come soon. Congratz!

Everytime someone writes something about a game (or a program) I download and try it.

I like Squish'em.

Thanks

I'm just curious since I've been spending some time with the Colecovision version of this strangely addicting game. Does the atari800 version have speech/digital sound like the colecovision version?

No speech.
