Heh.  The two gray cords connect to the Atari. The other 4 ports (only 3 of them are connected in this picture) are for the joysticks :-)

 

 

:dunce:  was thinking about my PS2's multi-tap adaptor, had forgotten you're using both 2600 joystick ports to implement this :lol:

After a good night of playtesting joust with my kids, I decided to try adding on another game, this time a combat/tank knockoff.  Having a lot of the 4-player framework in place from joust makes for some pretty fast development....

 

Awesome!  Maybe you could call this game "Tanks a Lot?"  :-)

If you are still looking for more ideas for small 4-player game ideas, maybe a Hungry, Hungry Hippos style of game could be fun?  Unlike the board game, perhaps the hippos could turn their heads when trying to chomp the flying food.

Ugh, and tonight's further tests show some weird static/interference on the screen on my Jr when I use the PCB version of the adapter instead of my breadboarded version. Something's different between them. I need to scrounge up another Atari to test though.

 

hello gauauu

 

Any progress on the board design and game creation/modification?

 

PGRE 2018 is fast approaching...I hope to play it again and take it home with me :lust:

Thanks for asking! Not a lot of progress right now -- I still haven't found a good solution for the weird flicker issues that it causes. I tried building a similar but slightly-different board design, to see if that would make a difference, but I get the same problem. Just this week I thought of a new idea to try, so hopefully if I get some time, I'll be able to test it out and see.

 

So hopefully I'll be able to demo again at PRGE (not sure if I'll be there, but I'd like to!) but I'm fairly sure it won't be ready to purchase by then :-(  But feel free to keep nagging me, I'm more motivated when I remember that people are interested!

Sounds like a cool idea!

 

As for 4-player games, how about a 4-player Surround/Light Cycle type game?  With better resolution than the LEGO block thickness of Surround, of course.

I've thought about that one, although I'm not sure I'm smart enough to come up with a way to do it with better horizontal resolution than surround did.  And I think that the board would get too crowded too quickly with surround-sized walls and 4 players.  But I appreciate the suggestions!

4 person Surround would be great, and if there are less than 4 people available then they can be auto-AI controlled.
 
Intellivision's SNAFU is quite fun with 2-players and 2-AI bots, or even 1 against 3.  Its AI is quite dumb, too, but still fun to play.
 
Surround has a few additional modes that SNAFU doesn't have, but the SNAFU music is so good.

Stell-A-Sketch is able to make really fine lines
 

 
 
 
So maybe it is possible to make a 4-person Surround that has smaller lines than the original, but wider than Stell-A-Sketch

Does the rf interference happen just from the adapter being plugged in or is it something that happens with button presses?

With button presses.  I'm guessing the level change coming out of the multiplexer is somehow different enough from just a regular level-change from a joystick, that it's somehow doing something "bad".

My current design that I'm testing involves turning off the adapter during the kernel, and that seems to be a big improvement. Maybe it's just hiding the issue (the RF interference still happens, but only during vblank so you can't see it?) We'll see.

Interesting. Thanks for the answer. I asked because I have had this happen with a couple of third party controllers from back in the day. Push a button, a static pattern appears. Thought it might be somewhat useful info to know it has happened with original equipment, albeit 3rd party.
