I bought mine on ebayz off this guy for a couple bucks

you would want one that goes the other way though, or i guess old gyromite carts or similar one have an adapter already inside them.

ok so let's say the cic chip is damaged, would it be plausible to pull one of the chips of a nes cart and put it in place of the one on the nes itself? Well first I'm gonna try running the data out pin to the data in pin on the CIC and see if that tricks it out. I believe this would be lifting the l...

If i bypass the chip completely how would that work, since the cart would still contain the other chip. Would this halt both chips then? I dont think I damaged it internally but if i did, from reading the docs anyway, I could try cutting the clock to the chip or just cutting power to it like you sug...

the cap is installed, i was just curious about it was all

everything i read about the lockout stated if the pin was broken it shouldnt matter since it is no longer getting the 5v, i dunno, right now the only avenue i can think of is to install a toggle switch and play with it that way

hmm I disabled the lockout chip, i was originally planning on bending the pin up and running a ground to it, but ended up breaking the pin off in the process, which should have the same effect maybe i need to replace the lockout chip and run a proper ground to it (pin4)? I think im just going to ins...

Hello all, 1. I received my usb copynes and installed it. Games played fine before hand, now some games still work fine, however others, mainly newer ones, give a gray screen. Black Tengen games will start but will replay the title screen like some sort of software reset, and other games and the gam...

I figured it out, appears the text file was wrong, when decoding the code the text did not explain to make the high bit low if it is high and not touch it at all if it is low in the address conversion.

So basically a quick fix:
if (bitThirteen == "1")
{
bitThirteen = "0";
}

Hello all, I was bored and coded a game genie decoder in C# after reading a few docs on how it works. The problem I'm running into is this: When I follow how it works reading this doc: http://tuxnes.sourceforge.net/gamegenie.html or this one http://nesdev.com/nesgg.txt we take for example this code ...

do you know where I can get some of the pirate carts? I dont have access to those.

i just bought one of these, lets figure it out?

got a willem programmer rev 5 and the W27C512-70 chips are erasable and reprogrammable for anyone future reference

they are 512 chips 64 X 8

thanks

neat but does anyone know where I can get a cart to do this? I have all other components except the "23C3662 based cart", It looks like you are working on a new pcb?

Well I got my eprom eraser and willem programmer yesterday. I am able to read the winbond chips however when I read the 8M chips I get a different checksum each time so I wonder if the willem is having trouble with these chips. M27C801, so I use the settings for 27c080/801. Google doesn't not have m...

I might end up doing that to get a power pack, but I like wiring and soldering anyway so im gonna make a few this way, I would be willing to trade off some 8meg chips for other hobby items if someone wants some of them that badly. I work for a cabletv/internet provider and we are in the process of u...

I know it is a big waste, but I have a whole lot of old cable modems that are getting pitched, im talking at least hundred or so, each one has an 8M eprom in it, so it's free and there is plenty

thanks for the tip, I will check out that part of the forum
