    I could see two options:

     

    A. Interleave two notes on one sound channel.

     

    B. Make the sound engine interrupt playback on one channel and play back a sound effect on it.

     

    I don't mind blippy simulated stereo as I grew up on Apple IIs and IBM PCs :)

    I was curious about it as a teenager. Didn't actually play it much when I could finally afford it as an adult.

     

    What re-kindled my love for it was a friend ported one of my Atari 2600 games to it. I'm not accomplished enough for that to happen!

     

    New games. Amazing developers. Great enthusiast base! What's better than that?

    The "#$2E" in the original ASM isn't a memory location, it's a literal constant value. So no memory would be saved by substituting your bB constant for the #$2E.

     

    If you want it just for convenience, then you can just put "lda #_mystatusbarcolor" in the asm code, instead of "lda #$2E".

     

    Holy cow that's amazing!! Thank you for the tip!! ^_^

    So, I'm trying to save variables yet again. I'm thinking that a status bar color will never change during the game and want to use a constant. How would I declare a constant in bB and have it referenced in the assembly code of a mini kernel?

     

    For instance, I changed the color of the status bar to yellow (#$2F) in 6lives_statusbar.asm

     

     ifconst statusbarcolor
 ; only write COLUPF if color variable exists, otherwise use existing PF color
 lda #$2E
 sta COLUPF
 endif
    How would I declare a constant in bB
    const _mystatusbarcolor = $2E
    and have that replace the
    lda #$2E
    in the code?

    I had a friend install a Linux distro that automatically dialed out when a program asked for Internet access. Also, it was smart enough to disconnect when nothing asked for access. Plenty of connects and disconnects were made that week.

     

    Unbeknownst to me my parents had gone for a cheap phone plan that had a limited amount of local calls per billing cycle. Reinstalling Windows and grounding ensued!

     

    Basically, my modem journey starts at 14,400 baud and ends at 56k. I missed the BBS era on my non IBM PC machines. Seems like an exciting time.

    Probably misconstruing what yer sayin' MrSQL. It sounds like you're justifying publishers making unauthorized copies and fully aware "collectors" buying said unauthorized reproductions.

     

    That can't be it since you've been an enthusiast and in the business for a long time. Maybe I need more coffee :)

    Hozer makes very poor cartridges with very bad printed labels. Just like Inky above, Hozer has taken the hacks that I have posted and used the story word for word and also any label that I had created. If you try to contact him you either get no reply or a response that seems like a manifesto with government conspiracy and other things attached. His reply is usually very incoherent and belligerent. I always see post asking where is the ROM/BIN and the reason I no longer post the ROM/BIN is basically Hozer. So the next time you wonder where is the ROM/BIN is then thank Hozer. He also supplies almost all of the EBAY and ETSY pirates as well.

     

     

     

     

    Not fair to blame collectors for collecting, they are buying the games - it's the vendors responsibility to conduct business fairly.

     

    I thought my games would fly under the radar and not be of interest to pirates. The posts above make me think of the collaborations I've had with Neotokeo2001 on Twist R' Shark, Zombie Road Kill and Strange Land. I know if I see unlicensed repros out there it's going to effect my enthusiasm. :(

     

    So, yeah. Collectors buying unauthorized repros contribute to the de-motivation for legitimate publishers and developers.

    They would have to be unbranded versions. Also, one at a time since each game would be original code.

     

    Any love for Jumpman or Jet Set Willy type games?

     

     

    UPDATE: Being in the business for awhile I should have assumed you knew all about proper licensing for titles.. and the liability that comes from taking the time and money developing games that you do not own the rights for.

     

    What licensing deals have you found? To be honest it wouldn't have to be super high profile. Even though it's sometimes hard to track down the rights holders a rare / sleeper hit would be more interesting to devote energy to.

    What ever happened to the 2600 RPG that was going to be like 1MB and needed a SARA?

     

    The largest ROM size I can use is 256k due to the compiler I use. So, this might be a different project you're thinking of?

     

    Still working on getting the technology. In the meantime I'm planning around the worst case scenario of 32k ROM for this particular project.

    I'm trying to determine the most susceptible display device to the screen roll that comes with going over-cycle. I figured the most touchy one is the one I'd use for hardware testing.

     

    So far I've got:

    A modern TV with RF tuner.

    A VCR attached to a Commodore 1702

     

    I need to get a plain, old CRT TV.

     

     

    In any case, are my first two options good enough? Is a stand alone CRT TV with RF the best option?

    wow, did you release a rom bro? I see this in the jazz trading commnity all the time with rare tapes- someone has a rom so rare and they will only trade with you if you can offer an equally as-rare rom

     

    Still in development. Status bar on the bottom is probably going to be re-written soon. It won't be rare as this is a new game created from scratch by myself.

     

    I'm going to try and make this the least rare I can on a physical cart.

    Long story short is that I have a zombie book series and think an Atari Game might be a good way to generate interest in it. I have a game idea in mind (similar to Berzerk/Disks of Tron). Is there anybody out there that might be interested in producing a game for me? Oh, and this would be paid of course.

     

    The price can change based off of what kind of rights the developer gets and how flexible you are with the game design. For instance: the Atari 2600 has only 2 hardware sprites. This makes games like Berserk more complicated as the programmer must manage multiple virtual sprites while not running out of CPU time.

     

    Feel free to message me about your project. Even if something cannot be worked out I can give you some directions to go in.

    The multi sprite kernel is not the best place to start making games with bB. I'd consider getting comfortable with the standard kernel before dipping your feet in.

     

    When I started messing with it I took an existing working example and played with the code until it was mine. Feel free to do so with this code here:

    You'll note I place all the player sprites in specific places and define graphics for them. If you don't they'll cause artifacts on the screen or flicker. Also, the playfield can get wonky if you don't load in a correctly sized playfield data right off the bat. The graphical objects don't quite line up nicely like they do in the standard kernel either. You must also make sure there's at least a few lines between each virtual player otherwise flicker happens. Lotsa gotchas :)

    The Atari community sure likes its drama.

     

    Which confuses me a lot. A TOS replacement already exists. We already have the MiST machines. Everything Atari IP free and built from the ground up by enthusiasts. With a little more cohesion I could see running a modern ST having more productive discussions right now.

    pfread requires an assembly add on in the multisprite kernel.

     

    Here is info on the official stuff:

    Bogax also made his own pfread funcitons for multi sprite:

    http://atariage.com/forums/topic/213386-pfread-for-the-multisprite-kernel/

     

    Neither option has worked for me. My hunch is that smarted brains could get an example working with bogaxs code.

     

     

    I've figured out how to use the ball as the collision object for the player0 sprite. I've provided a proof of concept that collides with walls without visible rebound and also slides against walls.

    I usually use the titlescreen editor in VisualbB. I hit the preview button and while the emulator is running I scrape up the temporary "titlescreen" folder and put it into my proper project folder.

     

    I put the title screen event and title music playback engine and data in bank 1. Bank 2 is the main game. Bank 3 has general routines (that can afford the bankswitch CPU cycle penalty) and game win / game over events. The titlescreen.asm is loaded in bank 4.

     

    This 16k layout is more than just personal preference: it has saved my arse many, many times.
