NES CIC CLONE

The ASM file is just a text file containing the assembly source code of the AVRCICZZ so you can open it with any text editor even on OSX.

Yes, I should have clarified that I had already done so. It's just that there's no default program associated with the extension. I now see that it's the source assembly code with comments and it all makes perfect sense.

Krikzz, how does the region changing and LED work? Does it just rely on the console resetting itself in order to cycle through the different CIC codes?
Also, is the LED pin 3 high when your program cycles to a new CIC code?

I'd like to figure it out on my own, but that AVR assembly code is so foreign to me.
I think I've just been inspired to learn some basic AVR assembly

LED light up upon region change and then turn off as far as I know. I don't really see why the LED would be needed unless you're just testing your chip (or to flash a LED on the nes everdrive)

(or to flash a LED on the nes everdrive)

Bingo.
Is an LED installed into my Everdrive cart necessary? Not really. Is it cool? I think so.

I wouldn't include it in an homemade mod but I got to say it would be nice on the everdrive PCB.

If correct region already selected, then reset pushing will not have any effect, but if cic detects that system locked, then happens next:
1) first 3 resets, cic just trying to unlock system like usually
2) after 3 failure attempt to unlock the system, cic will try to swith on other region (change key/lock codes).
3) led is shine, each next reset will switch cic to next region (4 regions total). Once correct region will be selected, cic will remember it and led will be turned off

I got european pal system for test, after some changes avrciczz start working with pal system also. So here avrciczz v2. Cic still should be tested with Asian and UK/Italy/Australia NES version

Alternatively, you could also just use any regular salvaged NES lockout chip from a cart of your region but you would need to follow the official NES CIC pinout for that (Can provide info if somebody is planning to go that route).

Please do post that information. I'd like to see it. 

Here's a quick pin-out comparison, this should give you all the info you need to hook it up:

You just connect the equivalent pin according to the pinout I gave previously (or found in the ASM file). And yes, the unused pin of the CIC should be ideally tied to ground though I doubt it would be a big deal leaving them floating.

No problems!

v3 will be released bit later, it will include UK systems support. I kill my testing attiny, so i have atmega16 build only. will release after tests with attiny
