hey all, new to the forum but have been creeping wtihout being a member for a while now.. a few months ago i bought a 7800 system without any cables or controllers, i had the video, ordering the power was easy enough, but given the general review of the proline controller, i decided to build my own controller from arcade parts. seems to have worked out okay for the most part, the 2600 and 2600 games recognize the controller right off. i used http://atariage.com/forums/topic/219466-diy-7800-arcade-stick-help/this post as a rough guide, including the pinout incorporated therein. the major difference is the base wire i'm using is chopped up cat5e, mostly because its what i had laying around the house. now for the particulars, i have 620 ohm resistors in the ground wires for each of the two buttons, and diodes in the lines running to pins 5 and 9. without the diodes i get a weird auto fire feature mentioned elsewhere in the forums. the ground wire for each button has its own line running to pin 8. as far as i can tell everything is wired "correctly" based against info found elsewhere in the forums. so thats good.... except using xevious as a test cart, i can use my joystick, but not the buttons. like i said running it against seaquest using the 7800... everything works fine. xevious or asteroids for the 7800... get me nothing. interesting side note, joust, robotron, and galaga all seem to work fine from what i can tell any ideas on what went wrong?
