Post by: Drummerboy on July 13, 2010, 10:21:05 PM
Hello,

I remember exists any Hard hack to conect any NES Gamepad (look pic) to the Amiga.
Anybody know where is the schematic to do, or have the schematic.. Its necesary change the conector to DB9, obiusly, but i dont know the pin order to soldering
Suggests, comments, are welcome.-

I believe those are serial devices 'like' PS/2 mice, so you would need a software driver as well.

You would have to rewire the whole pad.

Why not use a Sega MegaDrive controller instead?  They plug straight in without any modifications*

Yes they are serial devices, but, you do not necessarily need drivers, well, not for the Amiga that is. You can as well put a microcontroller (like an AVR), and upload a driver to that. I remember I saw it once, a demo of the nes controller attached to an Amiga. Then again, if there isn't a driver for it, my guess is that it won't be much of a fuss to make one yourself, if you can write c code. As the nes controller has 8 buttons (4 direction buttons and 4 action buttons (start, select, A, B) my guess is they put the controller status in one byte, one bit for each button. The only thing to find out is what kind of physical and connection protocols they've used (my guess is RS232, as it is the most common and therefore most likely the cheapest for them to implement).
Though you WILL need cut the controller cable because the nes plug is proprietary (IIRC). Though you can as well make a pass-through, as the cable is quite long.

-edit-
some more information (http://www.mit.edu/~tarvizo/nes-controller.html)
Hm, so I was wrong about the RS232 part. Perhaps back then it was too expensive, and/or too slow for this purpose.

Yeah, i was forgeting that.. i will obtain a Sega Megadriver Controller..
I just wanna try with that NES Controller becouse i have one, and i not use for anything.. and today cam to me the idea, to make a hard hack and use with the Amiga.. but i will discard the idea, becouse i no have desire to do much. Maybe later. Thanks Speelgoedmannetje for the link, there are all the info!.. :cool:
I was with it was just change the connector.

Anyway Thank you Guys for the suggests and comments..:afro:
