Subject: [stella] debugging w/ an emulator and other thoughts From: KirkIsrael@xxxxxxxxxxxxx Date: 16 Sep 2003 14:18:27 -0000 |
I was looking over http://www.videogamecritic.net/2600.htm , hundreds of atari reviews. I'm amazed at how many games I've never played or even heard of of, for that matter. And now, having been hacking at coding for a while, it's kinda fun to play the "what elements are doing that" game...sometimes it's easy, sometimes it's very hard. Anyway. I was thinking about how much easier life would be with a good debugger... one that could read in a DASM list file and show your variables by name. (though given various tricks for RAM reuse and reference, I guess that might be trickier than it first seems.) One thing Z26 could use is a button that says "just dump one frame's worth of trace info". It's kind of intimidating to get like megs and megs of raw material just for a few moment's of recording. I've tried to to use PCAE's debugger, but the interface is so difficult, combined with having to get past not having any variable names, it didn't help as much as I thought it would've. Ah well. I'm still able to make progress, but slowly. It took me a few hours last night to realize that I really need to stop trying to reinvent how to do a simple comparison, and should just crib from where I already do that in the code...for some reason, between knowing what flags I have to clear when and remembering which value is acting as if it was being subtracted from which, flag wise, it's non-trivial for this ASM n00b. But at this point, I have a kernal that should fully support "Poorlords", and now thanks to the Horizontal Positioning technique I got from Andrew Davie, I'm detecting goals without the use of collisions w/ the playfield. (hence the need for numerical comparison) Cheers, Kirk -- KirkIsrael@xxxxxxxxxxxxx http://kisrael.com Life's too short for sentences that begin "life's too short for..." --Slashdot ---------------------------------------------------------------------------------------------- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
