  1. thats neat i wonder if its the same as it is on world of sports https://atariage.com/forums/topic/291497-just-had-mind-blown-about-california-games-bmx/?tab=comments#comment-4280422
  2. i guess they didnt feel they sold enough units to make it worth while they made plenty of games for the c64 demon attack,moonsweeper,dragonfire,chopperhunt,nova blast
  3. when i made my altoid tin controller its just 4 push buttons up button is connected to 9,11 down button is connected to 11,15 left is 9,10 right is 10,15 you connect a resistor between 9 and 11 for uppy downy and 9 and 10 for lefty righty
  4. its neato not exactly a "company" making it its very simple to wire up a controller i've always said the hardest part is finding an "enclosure" every one is either too big or too small if anyone saw my attempts at home made controllers ive gone through altoid tins up through a metal power supply box i guess the problem i note is arcade machines use joysticks because it mounted to a giant unmovable enclosure the atari 2600 joystick works cause its fine to hand hold and press the one button with your thumb but when you get to 2 buttons it gets more tricky companies have been using heavy steel plates and feet and even suction cups to replicate the feel of a stationary arcade cabinet it is cool that it is a right hand stick so many arcade sticks are left hand stick the second hardest part is finding a plug that fits in the 5200 jack i wish everyone luck making joysticks ive come to the conclusion if you are going to hold it in your hands it should be ergonomic i just use a gravis gamepad and a pc adapter
  5. in my altoids controller i just used 2 240k resistors 220k is probably ok too treating each direction as a button is easier to wire them individually so button up should be from 9 to 11 with a 240k resistor across the terminals button down should be from 11 to 15 button left should be 9 to 10 with a 240k resistor across button right should be pin 10 to 15 the reason this works is that 240 is the default resistance till you hit up or left then its a dead short so the charging circuit is seeing rapid charge if you press down or right it is grounding it out so its seeing no charging which is the same as infinite resistance left and up is like fire hose full blast centers is like a garden hose and right down are like a dribble or nothing if you want to make it deluxe use a 500k potentiometer in place of the resistor to dial in your center but i find consoles are very forgiving and self adjust after a couple resets on off cycles i just used 8 conductor eithernet wire you really only need 6 conductors for the bottom row directions and buttons and i use the other 2 wires to connect pins 4 and 7 to activate start
  6. well i got my first 5200 in a trade in around 1987 for a sega master system it came with about 20 games superbreakout pacman galaxian centipede tennis digdug berzerk moon patrol vanguard space invaders robotron pengo mario bros jungle hunt joust defender choplifter football kangaroo ms pacman
  7. yea the controllers were lacking but yea the 2600 was still on shelves in 1990 probably the last year i remember them at kb toys there was a flood of master system stuff about then
  8. i would suggest putting in missile command and see if you can center the cursor pull off the actuators then place them back on at the 9:00 and 6:00 positions the 5200 self calibrates and is pretty forgiving just doing a few circles and power cycles
  9. neat work i wonder has fear(figure 8 racing) been modified?
  10. you do not need active components you only need them when you are converting to serial or are using a 2600 controller with a common ground since you are using a breadboard with individual switches you can replicate a digital to analog contition by using a 220-240k resistor for the center of each vector so one for uppy downy and one for lefty righty with the uppy downy one you just use the up button to short the resistor so that button makes 0 ohm now the trick is how to make a button press feel like 500k some just use a normally closed button that way when you break the contact it would be infinite resistance but there is another dirty trick you could play on the system if you steal a leg from the button ground pin 11 it will feel like there is no charging going on and the system interprets this as infinite resistance just repeat for lefty righty knowing that left is wants low ohms and right wants high ohms
  11. wico cable is only for the wico 5200 stick the 15 pin atari connector has the top row being the keypad matrix the bottom row is for directions and fire buttons the cable passes through the top row from the controller to the system and the bottom row is sent to the 9 pin wired in their special configuration if you have the wico y cable and do not have a wico analog 5200 stick you are not going to be able to do anything you can wire a push button to pins 4 and 7 on a 15 pin female plug jack it in and not need a atari controller plugged into the y adapter most games only need you to press start also the y adapter conductors can break so use an ohm meter and check each connection (remember what i said about top row and bottom row
  12. thanks works neato in the emulator i am using
  13. i wonder what nukey shay has been doing lately if we find him maybe we could beg to have him look it over
  14. i wonder if someone could optimise atari 800s star island https://www.youtube.com/watch?v=xajULLhhr5g
  15. check the archive.org someone been busy during the plague
