NES lockout chip

[+5-11under]

A few months ago I bought a couple of NES lockout chips (ciclone, a 10nes clone) from retrousb. I recently inquired about buying some more, but I was told they're not available for sale anymore.

 

Does anyone have any information on where I can buy or make these? Any help is appreciated.

Looks like it was invented by kevtris. Might not hurt to ask him for help?

Thanks! I just did that now. I also asked retrousb if there's a way to obtain the information. We'll see what happens... .

It looks like there's an answer here, although with different pinout...

Hmm interesting, what are you using the 10NES chip for? From what I heard that chip is more of a bad thing and isn't usually something people want to keep intact?

 

Are there any games that refuse to work if the chip is not present?

An NES "system" uses two 10NES chips. One is in the console (usually, at least the original, anyway). The other is in the game. When making homebrews to work on all consoles, you need one per game PCB.

 

Edit: bypassing the one inside the console is perhaps advantageous, but having it in the game cartridge ensures the game will work on all NES consoles.

I see, so the ones inside the cartridges are there mainly just for people who wanted to keep their hardware as virgin as possible and not break their NES system's lockout chip? I can understand that. I like keeping one of my NES consoles as original as can be myself while the other is disabled and had a pin replacement that I think needs to be re-replaced now.

Must just be a different design then. I thought I remembered reading that the CIClone used a PIC, but that could be wrong.

Yup, exactly
