Lockout

JackFrost22 · Post by **JackFrost22** » Sat Dec 04, 2004 9:29 pm

I just got my circuitboard etching tanks up and running and I'm making nes-famicom and famicom-nes converters I have the pans written up in protel but does anyone know how to disable the lockout chip. I might have to crack open my excitebike cart to fid out but I've opened it up so many times before

well, famicon-nes converters normally have lockout chips in them. I think you cut pin four on the chip inside the nes to disable it though.

without modding i plan to make them to sell cause my tanks pretty big anmd I could etch a lot onto the same board and then cut it

I read that one of the first ways that they disabled the lockout chip was to send a 5v something (negitive, whatever) into it and that made it fail but didnt damage it. Only problem is that later ones prevered this from happening.

Did you find a cheap place for 60 and 72 pin edge connectors?
I know I'm getting my nes-fami converters for fairly cheap

Yeah an online surplus electronics store its like 25 cents a piece

so how much do you think it'll cost you to build these a piece?
Don't forgot you need to manually solder on the connectors

I'll hire orphans todo that I think $1 to buil at the most but $12 to sell on eBay to you guys $1

wow, nice of you to sell them here for $1, you think you'll get $12 for them on ebay? If I order around 100 from my supplier I could probably get them for under $1 a piece after shipping

I'd like to confirm that. I did it, and it seemed to work.

I didn't have a famicom converter then, but it did not do the auto reset anymore, which is what the lockout chip effectively does. When the NES doesn't detect the key code from an official cartridge, be a pirate cart be inside or no cart at all, it does the auto restart we are so familiar with(the auto restart also happens when the system's connecter wears, so the auto reset is considered a symptom of a faulty connector. ^^).

Now you know what the reset does. I have heard that some Game Genies have trouble with unlocked out systems though. I haven't experienced it, so i have no idea if it is true.

P.S. You don't even have to reconnect pin 4 to ground. Just break it off the chip and leave it as a hanging pin. ^^

NESDev has VERY extensive data on the NES, including this.

Wow, most trial software that I've used leaves a registry key in the machine so you can't reinstall it again...

Same here... You'de think for a program as expensive as that would leave something.
