Found the culprit bad BNE call. Updated it. DefenderCity+ v21.bin

Nothing like playing your own game and finding a bug 5 years later. Needless to say, going to work this and and release a new version. It appears that if you are on screen when an abduction happens that you will explode no matter what happens. No good. I'll have to get a fix out for that. Not sure if anyone cares, but, its a matter of pride at this point.

Hi all, Not sure how useful this is but I'll post it anyway. I kept switching computers through the year and found the tools I needed for hacking and developing were not as easy to install as possible. So, I created an installer for them that I hope to keep up to date as new tools come out. You can download it from github: https://github.com/rallyrabbit/AtariTools-Installer Essentially I put dasm, splitfile, stella, distella, hackomatic in it. Happy to add others that people seem to need or want. I also have it set up the path automatically in Windows and the uninstaller removes it all. It's not rocket science, but it does save me some time and thought there might be interest. If anything else is missing, happy to add those in too. Jus thought this might be a way to help people with the toolsets.

Thanks sir! I've been reading up on your stuff for the past hour so. Simply amazing so far!!!! I have a lot of reading to do to figure this out.

Ask a vague question and get any answer that comes that's on me! Let me rephrase. Is there more formalized documentation on how to use the DPC/DPC+ feature set? I've read all the concepts on the original DPC, which sounds fairly straight forward if not a bit cryptic due to how it works. It's more a case of, as a coder, what specifics do I use to utilize this, recommended best practices, etc. However, your links lead me over to the Harmony/Melody club on AtariAge which I didn't know existed and that has a ton of stuff for me to go through. So shame on me for not finding that on me own!

I feel silly asking this, I assumed I could find some information on DPC (and potentially how Pitfall II is written) or DPC+... but I'm not finding any specific information on than sporadic notes... is there nothing more .... formalized?

It's going to take a while but i hope to take it, make the display slightly better, colors are little better, add some sound effects and maybe the test between stages like the arcade game had. The original was really good, but when some enhancements especially with the new boards, could really help to get a cleaned up game going on. This was one of my favorite forgotten games.

Hi all, Think I might try another hack to see if I can make one of my favorites a better game. This time the Atari 2600 Parker Brothers Gyruss. Question for anyone here is, before I go disassemble it, has anyone seen a disassembled copy maybe with some comments. I'd rather not start out be reinventing the wheel the someone may have already started.

Thanks gents. There's an interesting 8-bit game called Atom Smasher (not like the 2600), concept is cool. I haven't seen a 2600 version of it. Now that I think about it, I might be able to take asteroids as a base and start gutting it. But even then, it's going to be massive.

Been reading up the Atari 8-bit a little. I see a lot of games have been ported up to the 8-bit, just curious if its possible to port 8-bit games to the 2600. Looking at things, my gut says maybe but extremely difficult (almost like a rewrite). But curious for the expert opinions here.

Version 20 update. Fixed some routines based on the suggestion above. Fixed the smart bomb use. v20.bin

My apologies. So you basically, you attached the bin files with a fix. So, I used distella to extract and diff against my code to see where you made the changes. Those were the lines that distella output for sections that you changed. My label names have no all been cleaned up for sure. As I have added a removed lots of code, I haven't rampantly changed the labels to match up with the actual addresses yet. I was going to clean this up when I finally stopped coding. I think I get what is going on here vs what distella output, and only the absolute store to PF2 I think I confused something else you recommended earlier as well. So I maintained my loss of cycle here. Yes, the trails of objects are gone in the city, but I am still seeing the humans migrate around their locations corresponding to a building. On a side note, I did fix the smart bombs as well.

I've got nothing to hide in the source. This is kind of a group effort at this point. Here's the code. I am working on the smartbomb routine now, so bombs may not be 100% in this. bank0.asm bank1.asm

For the smart bomb fix, I think I can use a pseudo fire button debounce from the value setup in 0xAC. When the bomb goes off, it sets up a countdown in this value. As long as this is non-zero, I should be able to use it to block another bomb from firing.
