I just had to say, there's a lot of excellent submissions on the contest page. I tried to give it a shot myself, so I know it's not as easy as it may seem. (It's a good thing I gave up -- the beats I was coming up with would give Cthulhu a headache.)

 

By the way, does anyone else think it would be cool to have an Atari sound editor? Something with an easy to use interface that allows you to do anything you could do in assembly, a built in emulator so you don't have to wait to hear the results, and the ability to export wav and bin files.

Sounds cool.

 

I've toyed with the idea of making a 2600 cartridge that let's you edit beats on-screen. The problem is that there would be no way to save them. If you made your software able to produce Atari binaries, that would be really cool. Because then you can load them onto a real Atari using a Supercharger or Cuttle Cart.

Actually, I hadn't thought of doing it myself. I don't know assembly, I don't know anything about how 2600 sound works, I'm hardly a programmer at all in fact. But if it were limited to editing beats, that wouldn't be too hard, and maybe that would be a good project to do while I'm studying Java. It would be sort of like Len's web-based tool. Making bin files should be trivial, just use one that's already compiled and change the data bytes. Emulating the sound would be the hard part. I'm looking at the docs I can find especially TiaSound, but it's daunting to a beginner. Just what is self-modifying code?

A very dirty (an efficient )assembler trick. You change parts of the code on the fly.

 

Like changing e.g.

code
if (i < 0)

into

code
while (j != 5)

while the program is running. Cool, isn't it?
