Hey, I know this has probably been asked a thousand times, but I am little confused as to how to mod the 1chip SNES with the SuperCIC and uIGR. I have done several 3-chip SNES consoles with the basic SuperCIC but I have a 1-CHIP in stock that I want to do the full monty on.
Can someone post a link that shows the full schematic/circuit diagram for this mod, please? Using Google gives many different results and I would just like some reassurance that I am using the correct information.
Thanks.

Or buy my PCB kit and includes uIGR (works with games that poll the controller differently, unlike the original IGR).
Its on a custom PCB and makes the job much easier.

To clarify, in the picture you posted, when it mentions connecting to the CIC pins does it actually mean to the pads after you've removed the CIC? Or does the CIC remain in place for this mod? I seem to remember on the older SNES revisions you have to lift most of the pins on the CIC.
Thanks for the info! I have bought stuff from you before, and been very happy with it - but I do like to build stuff myself sometimes, to that end could you point me to the correct hex files that I should programme the PICs with? There seem to be multiple sources and versions of the files online and I just want to be sure I get the right ones. If I think it's too much bother, I'll get the custom PCB from you

I remove the CIC - as I find it easier than lifting the pins. But I have a hot air rework station, if you dont then lifting the pins may be easier.

OK great, thanks again for the help. Isn't it so that you need to put in a 10K resistor between two of the CIC pads if you remove the chip? (Just something from memory...). So, the CIC pins are the only ones where you are actually soldering to the pads on the mainboard instead of the chip? For example, it says CN3 goes to S-CPU pin 9 - does that mean you leave pin 9 attached to the board and solder the new connection "on top" of it?

If they are lifted, it says so.
You do need a 10k resistor if you remove the original CIC. My board already has this include however.

Quick question - is the 74HC00 equivalent to the 7400? I can't find the 7400 anywhere near me.
