How to access files on Disk?

[Stefan Both]

 .Guys,

I'm a total noob regarding (Atari) programming. Well the motivation to change that has come. I met a very good friend and we had an "Atari session" last night. Crawling tnfs Servers, we stumbled over a game named

"Airline". One of his favoured waste of time back in the days. It's aim is running an airline successful. However... it's turn based and the time for decissions is limited (120sec.)

It would much easier, to have at least 4 minutes. Thats where my ambition starts.

 

Well I did not came far...

Loaded the atr file into D2: and I think thats a kind of protection? Isn't it?

It was my hope, the game is written in basic variant...

So ? Err... how to get access at all?

gonna optimize the spaghetti once you get into it? get rid of all the crappy loops and block poke the data.

Doesn't look like this game uses either files or BASIC. It loads raw sectors off the disk and appears to be written directly in assembly, or at least a compiled language that can use integer arithmetic.

The game uses "windows" and the filling routine is damn slow. Thats why I thought its probably a basic derivate.
