OMG im so dumb, i have one of those ... ( an Action Replay )

but hey, my cartridge I thought I had blown works, I just redid the wiring

yet I had only crashes or freeze, maybe ROM is the way to go

How about feeding in stuff through a mega memory cart? Might be safer and you'd have sram to mess with.

This guy also try to extend the connector, it is this not go well for him either ...

the footprint on the PCB is for a 2x16 smt header, which will get you to a breadboard pretty easily (i use this PCB for prototyping new carts, myself).  where you can have the ROM for something to boot, but since its on a breadboard you can screw around with that as much as you'd like

its a breakout board for the edge connector in the cart.  makes prototyping (or in your case, manipulation) quite easy

(its also a jazzmarazz layout, big ups to jazz)

oh okay, yes of course we need something to boot up  ^^"

Otherwise, no one is interested to experiment ?
I'm sure it has potential

The picture is of a bare PCB.

What do you mean by " you'd have to give the GB something to actually boot up" ?

Bending was the first thing I thought of whe Kitsch released those.  You'd have to give the GB something to actually boot up, of course.

Please tell me it isn't so

Thank you, this is a cool project !

I had a another mod in work, a DMG with a cartridge slot offset/extended (to put in a keyboard) :

it would have been very easy to mess with the cartridge.
But strangely, only the original grays DMG games works, the three right one "with colors" don't boot ( even if the Nintendo logo is still displayed correctly ). :-(
That's why I wanted to directly solder the wires to the RAM.
This is probably because of the length of the cable, the connection is bad, I should try to shorten.

did this little photoset like 2 years ago, nothing fancy

(GBA SP is cool because it gives u room to mess with the cart while its running)

Bad news for me :-(
Someone already try that ?
Even playing with only the "Data Input/Output" pin or the "Address Inputs" one ?
Because i read many story about old crappy cartridge with weird glitch caused by oxydation, dust or damaged trace ( battery leakage )
I even have a friend that had one of these cartridges ( https://www.youtube.com/playlist?list=P … b0XqVNxR2t )

I think i fried a bleepbloop cart. Jazz is right.

Bad idea. Bend the vram chip inside the GB itself, but don't burn it out!

Hi everyone, first of all I would like to apologize for my english not always correct, I'm french and sometimes uses a translator ( also im new here )

So here is my project, I wanted to mod a pokemon cartridge (Y/R/B) for making glitchs (like on some used/oxidized game ) with some switch on top ( I precise that I have very little knowledge of electronics, this may sound dumb but I'm very curious )

I then open a cartridge and have focused on two big chips, the ROM and the RAM ( GM76C256CLL70 )
I thought I could create errors by shorting the RAM on some pin so i found the datasheet → http://bit.ly/1q5WFNd and i solder a old IDE cable on the chip ( i taken only the Vss, Address Inputs and Data Input/Output, because I do not know what the other are doing and Vcc is probably dangerous )

And you know what? I burnout the RAM because the game don't boot...  yea, just with my soldering iron ...

So, before I try again with another cartridge, if someone who is not a noob like me could tell me if it had a chance to work, that would be great

Thanks in advance
