PAC-MAN-RED Posted July 21, 2011 Share Posted July 21, 2011 (edited) A quick mod of a Genesis controller I did. Just thought I'd share this further. I Originally posted it here: http://www.atariage.com/forums/topic/169238-free-sprites-for-the-taking/page__view__findpost__p__2327967 I call it the MegaMan Mod, and if you read through the the above post you'll know why. The first 2 buttons, Fire(B) and Jump(A), are in the NES configuration with the ALT-button replacing the C-Button. B-Button is the original 2600 fire button, A-Button is UP on the 2600 Joystick, and the ALT-Button is DOWN on the 2600 Joystick. The ALT-Button also provides one combo button press, impossible through normal means, UP + DOWN together. Which might be programmable in Batari Basic or maybe assembly? In any case, I hope it's viable. The soldering is a little above NOVICE because of the small traces. However, you can improve your chances of success greatly by using a 45W iron(30W will do, but I prefer 45W), single strand wire as thin as you are comfortable using or can find, and silver solder. NOTE: Inside the Genesis 3 Button controller there is a large rectangular shaped piece of plastic around the Start button that may have to be trimmed a bit, so be careful. Here's a list of games that use UP as Jump and will work immediately with this mod: Moon Patrol Sorcerer(Mythicon) Smurf: Rescue in Gargamel's Castle Frogs & Flies - I tested this one myself and oddly enough it supports all 3 buttons! Kung Fu Master Kangaroo Swordquest: Earthworld I'm sure there's more, but this was all I could find.

Rex Dart Posted July 21, 2011 Share Posted July 21, 2011 (edited) Hey, cool idea. The kind that seems so obvious in hindsight, but clearly wasn't or it'd have been done before. Sounds like it'd make Mountain King work a little better. I bet you can get some interesting behaviors out of VCS games with up&down simultaneously.

PAC-MAN-RED Posted July 21, 2011 Author Share Posted July 21, 2011 (edited) I bet you can get some interesting behaviors out of VCS games with up&down simultaneously. Like this weird glitch I found at this site: http://www4.ncsu.edu/~awwatkin/ATARI/2600/2600cheat.html ---------------------------------------------------------------------- Ms. Pac-Man [2600] Atari Press up & down at the same time. Ms. Pac-Man will go left and get stuck in a wall. Let the game enter the demo mode, then play with Game Select. The monsters will appear and disappear as they move around, depending on the difficulty that's currently selected. Useless, but amusing. ---------------------------------------------------------------------- Illya Edited July 21, 2011 by PAC-MAN-RED Quote Link to comment Share on other sites More sharing options...
RevEng Posted August 6, 2011 Share Posted August 6, 2011 Nice trick! I came up with an alternate approach a while back. It's also worth noting that it's possible to read 2 buttons on an unmodified Genesis controller, and Wickeycolumbus came up with an adapter to fully support the NES controller. Each method has their pro's and con's, so welcome to the party. Quote Link to comment Share on other sites More sharing options...
PAC-MAN-RED Posted August 6, 2011 Author Share Posted August 6, 2011 Thank you. I knew that those high school electronics classes would be useful one day. With the this controller mod, I wanted something dead simple so that even someone with rudimentary electronics skills could understand it. No ICs, capacitors, resistors, or extra components of any kind. Also, after doing research in the forums, I found that there were people that didn't mind Up on the controller being Jump, and those that outright hated this idea in both official and home-brew releases... this design satisfies both.
