    I don't know why I'm the first one to notice this... If you'd just stop bickering you would see :-)

     

    I've managed to translate some of it. With my keen intellect I have deduced. That the top three lines of text end in an exclamation point! Thus they are probably selling the features of the cartridge.

     

    I also managed to carefully translate the number 16 at the top, which led me to believe that maybe this is a 16 game multicart... and sure enough there are 16 blocks of text below the ! text. Which are probably the names of the 16 games contained on the cart, which mario is so wonderfully listing for us on his scroll.

     

    You lamos, you let a stupid white boy figure it out.

     

    :D :D :D :D :D :D :D

    I'm out of the custom joystick game :-) Too expensive, and too much work for everything else I'm planning. The vibration mod was only a cheap quick way to add something else to your joystick... however if someone else wants to go create custom joysticks... that would be awesome!!

     

    What I really need molds of is Atari cartridge casings. I'm not a subscriber of hacking up old Pac-Man cases for our homebrews... I don't see why we can't create our own plastic cases. PM me and lets talk about how we might get into making a mold for cases.

    The 2600 has a native maximum of 2 sprites on one scanline, this can be overuled with clever programming, but that is how it works basically. Because there is only one demon on each scan line at a time, they used the two sprites allowed on that line to animate the demons coming together.

     

    I always thought that was cool too.

    No not barbeque potato....

     

     

    I thought the 2600 on a chip was just a work in progress with tons left to do, but a visit to the site today reveals to my surprise, that he's already finished the TIA/PIA and 6507 core... and he's got screen shots of it working and such.

     

    All that he has to do it write the 6507 software and it's a reality! Oh man I am SO going to make some cool crap when this comes out... I thought I had to wait ages still.

    I just looked at my switch, and it says "Property of XXX CableVision do NOT remove!"

     

    Ahhhh.... those were the days when the TV providers actually installed the equipment you needed for your gaming...

    IF you dont like the idea of breaking open your Atari joysticks

    you could always use a cheap 2nd party joystick. ;)

     

    Yeah, some are compatible with my mech, they just need room for it to spin and cause the vibration. My Wico stick does, however another 3rd party stick I have does not have the room... But that is of course a solution.

    well i was digging through the box and i found a tv/game switch but i have a newer tv so i dont have the VHF things to unscrew and what not.  :x  

    this is really pissing me off as i really want to get down and play all these awesome looking games!

     

    You need one of those little dealies that converts the two prong VHF output to COAX... I've got zillions of them :-) I wish I could help you out!

     

    For fun I go to radio shack and stare at the cell phones for a minute... They must get mondo commision on those because you will immediatly be mobbed by them.

     

    "You need help with a cell phone?"

     

    "No, just looking"

     

    "Well when will you not be looking anymore"

     

    "I don't know when.... I'm just looking."

     

    "Well you must be done looking by now, let me show you what this one can do"

     

    ^^^^^ Really happened :-)

    Exactly, I was thinking of alalog to digital converters, arent the signals going into the IO section of the 2600 joystick port run through a hex inverter or an AD converter before getting to the microprocessor??

     

    The instructions don't go to THE microprossor, they go to another chip called the RIOT or PIA chip. The inputs go straight to pin's the PIA chip. The 8 bit addresses on the PIA chip are read as a standard address from the processor just like everything else, I'm sure it does not travel through a hex inverter first.

     

    The console switches are also wired to different pins on the same chip, it's a pretty cool chip in my opinion ;-) and it holds the RAM and all timer functions too. Stella chip eat THAT! :-)

    Those are both tricky but doable techniques, not for beginners though.

    Just so you don't get confused for those of you who don't really know about electronics, I just had to mention that Emmanuel Fernandes says in his description of the atari-pc interface that Atari joysticks are digital, well I see what he was getting at but in  NO way are Atari joysticks digital, they are 100% ANALOG. :)

     

    Uh... They are digital. Digital implies that each input on the Atari Joystick has two states, off an on, 0 and 1. That is digital, and that is exactly how an Atari joystick works. The 2600 reads each of the inputs as HI (1) and when you close the switch by pushing the joystick it goes LO (0). Opening an atari joystick and probing the contacts with a multimeter will proove that the joystick is controlling the state of the pin, it is not being converted inside the console to digital.

     

    Analog joysticks are used with PC's, Which allows software on the PC to interpret how far you are pushing the joystick, so characters can walk instead of run and so on, it's basically a variable resistor that increases and decreases the current on a pin and allows you to determine how the user is using the joystick.

     

    So to sum it up, Analog implies one pin can carry a multitude of states by varying the voltage on the pin, and digital implies that a pin has two states off and on. May be you were confused as to what he implied by stating that it was digital?

    There is no way to program the 2600 without the stella programmers guide... GET IT! :-)

     

    When I decided the only way to get my program to work the way I wanted was an ASymetrical Reflected playfield I for the life of me could not get it going... It's a super tight kernel but the Stella Programmers guide got me through it ;-)

    Back on the topic of the stick mods.. Instead of modding the actual sticks (ahving people send em off etc).   How about a unit that attaches to the underside or whereever of the stick and performs the vibration tasks.  Would require another cable to run alongside the normal stick cable.. and piggy back.. possibly incorporate an extension in there too?

     

     

    Sounds like a plan.

     

    Would it be possible to use the original LED flashing stuff for the vibration? therefor meaning that combat and possibly one or two others would have it already without need for modding?  (you would have to re-write your game I'd guess).

     

    I don't see how such a device would reall work.... Well I take that back, yes I do it just would be difficult to work out, you would need a "splitter" box of sorts so that you could run one cable from the stick and one from the vibratrating. I'd have to construct an enclosure for the vibrating mech that could somehow attatch itself to the stick base.

     

    While it's definetly possible, it'd probably cost at least $18 for cables/splitter components/Vibrating Components/and Custom Enclosure Components.

     

    To just put a vibrating motor in an existing stick would only cost like $4... and you can't even really tell it's in there unless you open it up.

     

    Like has been said before it's your stuff and if you want your sticks original inside and out, that's fine with me I'm certainly not demanding you send them to me :-) What's there to say that in 30 years all of this homebrew stuff won't become wildly collectable, as we only create a few of these items every time we come up with them.

     

    Rich -- I've never heard of this RF remote vibrating mech you talk about... maybe it will work instead of modding a real stick? Do you have a link to share?

  24. Posted

    I could easily set up a vibrating mech in Atari Joysticks.. and easily program popular games to make it vibrate at the right moment...   I acutally built a set here and modded Combat for my own use...

     

    I didn't think anyone else would be interested :-)  So I kept it to myself.

    Perhaps you could modify some Playaround games for the ladies—they might enjoy your vibrating joystick... ;)

     

    How do you think I got my wife IN to Atari ;-) You didn't think I made it just for Combat did you... lol

    It sounds like you're getting some RF interferance. Have you moved your Atari or anything else around it?

     

    Mitchhttp://atari7800.atari.org

     

    That's what I thought too, I hoped changing the channel might help... It seems pretty wierd. I could definetly fix it for you, but I'm not sure how to help you via a forum ;-)

     

    If it has sentimental value or you just really want it to work ;-) PM me and I'll fix it up for only the cost of parts if it needs any, and shoot it back to you.

     

    I've got a lot of spare time for a while so might as well give back to the community! :-)
