Yeah sorry I don't have any CIC code posted any more. I sold the project so I had to yank it all. There's plenty of info out there to make a new one though, and the SNES code that Ikari posted should be directly applicable to the NES CIC. Also I am unsure if an AVR would work due to cycle uncertain...

Sad to hear jims cool has disappeared, his combined NES/SNES CIC clone for AVR sounded really promising :(

So was the Tengen CIC clone by kevtris released? There seems to be conflicting info and googling just bought me right back here.

Quick question, was the NES CIC clone finished? If not is someone still working on it? It just seems a shame if there is still no open source NES CIC clone :(

I don't think the malfunctioning is caused by the S-DD1's CIC. I guess that it is working just like any other CIC (in "key" mode), so if SNES CPU is not reset, it means that lock-CIC receives the valid binary sequence from S-DD1, so it should be receiving the valid one too. So, Star Ocean doesnt lo...

It sounds like you are trying to run Star Ocean/S-DD1 on a PAL SNES with the lockout chip disabled? If so I read its one of the known 'problem' games (Like Super Mario RPG/SA-1) which can only be played on a console with a working matching lockout chip, in this case either a US SNES or JPN Super Fam...

Neoflash doesn't even have a FPGA; CPLD != FPGA. Erm, the NEO SNES Myth Cart uses an Actel ProASIC3 'A3P060':- http://digisalt.de/dsnesdsblog/wordpress/wp-content/uploads/front2.jpg This is an FPGA as can be seen from the datasheet here:- http://www.datasheetarchive.com/pdf-datasheets/Datasheets-1/...

Open source is not very appealing either as we don't need cheap quality clones or other general misdirection. Things are pretty good and certainly improvements and additions would be nice but nothing mentioned recently is vital. Genuinely curious here, but I dont understand how releasing the SNES P...

It may be a little bit off-topic but related to the snes powerpak. I may have missed the reason in all the messages that was posted but want to know: what make it so hard to make the powerpak work on many snes revisions compared to the game doctor that seemed to work on any machine? I'm just curiou...

Wow, thats really fantastic ikari_01 :D Thanks so much for all your hard work.

Out of curiousity, are you still considering making a NES/N64 CIC clone? Hope you dont mind me asking :)

I will probably just remove the original CIC entirely, as it seems like there would be less complications/wires that way :) For the 10kΩ resistor does it matter if I use metal film or carbon film, or if its 1/4W or 1/2W etc? Also, is it possible the PIC code can be changed to remove the need for a r...

Thanks for the reply ikari_01 :) Great to see it running Star Ocean. If I wanted to use the lock implimentation in my SNES console would it be best to completely remove the original CIC chip and connect the clone to the correct pads? Or should I just disable the original CIC (By turning it into a ke...

Really fantastic work ikari_01 :D I was just curious about the key implimentation - from what I gather it starts as one region, and if its incorrect it automatically switches to the other region when you reset/power cycle the console. My question is does it 'remember' the correct lock region setting...

Yup xc2s15. I don't know if software multiplier would be good enough for the 16x16+ needed, but certainly something to look into in the future. Chip is around 60% full depending what you look at so space may be an issue. FPGA config is on the CF card so it can be added later. Shame on you for not c...
