NES CIC CLONE

[KRIKzz]

Huh! After three days of crazy work i made my own AVR based cic clone for NES, woohoo! So, NES version of cart will come very very soon!

Good work Krikzz!

What about the two extra Famicom audio lines that go straigt to the expansion Port of the NES?
Will i have the modify my NES in that case, i think so?
Just an idea - a headphone jack would be nice or just solder-Pads on the PCB to add one.^^

greetings saturnu

Ypu will not able to hear nes internal sound with phones jack if your system is not modified

That is very cool to hear. AVR is much cheaper and less work than donor carts

How'd you go about recreating the CIC's algorithm? Did you just find a CIC ROM dump and use the same disassembler as the SNES? I've heard they're the same.

3 days is pretty impressive. Big congrats Krikzz! This is awesome.

I used Tengen.c to understand algorithm and timing, then i just make asm implementation for avr

nes version of cart will come very very soon. this is great news. so excited about this everdrive

excellent work krikzz as always

So yours works like a pirate cart or the real thing?  And what's an avr? Time for some googling...

Works like original cic, plus my cic supports any regions. AVR it is an Atmel MCU

Someone (jims cool) on Nesdev's forum was busy doing the same thing with a attiny13 except he's planning to have it work both as NES CIC and SNES CIC as far as I remember. Impressive that you managed to do it in 3 days! It's always nice seeing AVR get some love:0 Will you be releasing the binary or you are planning on setting the protection fuse and keeping it private? (just curious, no judgments!)

[KRIKzz]

I will release asm code and binary. By the way, i also chosen ATtiny13 for final implementation(I used atmega16 for prototype), this mcu even bit more cheap than PIC12F629

[SkinnyV]

Awesome news! That's pretty generous and should break the CIClone monopoly. I'll be sure to try it out when it get released as I have quite a few tiny13 laying around and I'm planning on replacing the CIC stun circuit from an old 60-to-72 nes adapter with one of those baby. Any thought on how you're going to name your creation?

krikzz how did you learn about all the different retro stuff? i really admire your work, wished i could do the stuff you do

I have always loved your approach with DIYers and we appreciate it. This is excellent news, indeed.

Name it the KobaCIC!!! Or whatever else you think makes more sense with pronunciation. If it's not obvious... I'm going for a play on "ковбаса".

Probably avrcic, or something like that.

Internet is my best friend (:

LOL "cало" would more actual than "ковбаса"  for Ukraine, salocic in this case ha ha
