Very cool joysticks still available!

Everyone probably knows that Sega Genesis Game pads work on Amigas and that they are available new at some of the game trading stores like GameStop.  I've collected maybe a dozen of these. Usually, because Sega is different, only 1 fire button works, but it's still a usable joypad.

Whats new to me is that a very simple modification turns these into fully functional 6-button joypads.  It was spelled out several years ago in the docs that come with ADoom, which was just re-released on Aminet.  I did this last night.  You simply swap the Vdd (+5 volts) and Sel wires inside the controller and connect a 470 ohm resister across these same 2 wires.

  Of course, most games won't use all 6 buttons.  But, it's nice to make these excellent controllers completely Amiga specific and compliant.  Even the rapid fire functions work!  These are better than the CD32 joypad.

If those controllers are for Sega,  then yes.  You get one fire button and usually, the turbo function works.  With the mod described above and in the text describing the ADoom archive on Aminet,  you get +5v correctly routed, all buttons work in ADoom (even Start and Mode, making 8 total), 2 fire buttons in other games that utilized them.  I don't know yet if other Amiga games were written to this Sega standard.  I believe this modified Sega controller will replace a CD32 controller for games written to that standard, but I haven't tested this yet.

My ISP is giving me trouble tonite, I'll be quick!  Do a search for ADoom-1.3.lha.  The details are in the Description text. If you DL the archive, that same text file is included with it.  It's just a verbal proceedure, no pics or schematic.  If I can get my scanner working, maybe I'll upload a view of the inside of the joypad.  E-mail if I can be of use.
