    It would help to know what system you are thinking about.

    Without knowing the system you are looking to do, you will at the very least need an EPROM chip and usually a hex inverter to replace the original masked ROM. In addition you would need a programmer or someone to program the chips for you and a donor cartridge board. Older systems like the 2600 you can either reuse a cheap game or else buy new repro boards. Many newer systems require custom mapper or bank switching chips which if they can't be reproduced then you will definitely need to use a donor game.

    Do some searching on the forum as I'm certain this has been covered before ad nauseam.

    I've been wanting to this for a while myself. I want to make carts for the Genesis.

    This should help you.

    Default What about NES?

    I have no idea where to even start with this, but I'd like to make some new repros. Any good tutorials out there?

    yep i would like to learn about the nes thing as well.
    i started by getting nesticle the emulater and a few games.
    i messed around with the pallete thing changing colours.
    im kinda getting the idea for it
    what i want to do is hack a gunboy and put as many original games on it as possible. that way i can carry a small console/controller/game libary in one neat little pack
    there are a few books out on amazon, one by ben heck i think, shows how to make a portable snes.
    i have a 500 in 1 electronics lab that goes through hex programming. im working through that to learn the construction side of things

    Is there a website that has the labels already sized and ready to print for repos like Galaxian, California Raisins, etc?

    Apparently the experienced repro makers consider the SNES among the most challenging of all to do. I've seen the inside of a repro SFC Bahamut Lagoon, and Good God, I am a very skilled solderer, and I would not touch a project like that with a ten foot pole.

    However, I have an eye to 'profitability'. If time is literally no object, it's probably a rewarding project.

    Essentially what you do is get a donor cart...a cheap or otherwise worthless game that has the same hardware(mappers and bank switching chips) as the game you want. Remove that games ROM chip and replace it with your own. You can even use a flash chip so you can easily replace the game with another one later. The rom/flash burner can either be bought or made yourself. I made my own gameboy flash writer and it was pretty straight forward.

    I've only done this for testing homebrew gameboy games but the concept is the same for making repros.

    Here's an exelent site on making cart programmers...
    http://www.reinerziegler.de/

    It covers gameboy, gameboy advance, and snes among others. If you have the ability to program your own microprocessors he even has some pretty spiffy schematics for usb cart programmers using a single chip.

    To get an idea of what might be involved...here's a modified gameboy color cart made to hold more than one game.


    A single game cart is much much simpler but your still working with surface mount parts, very tiny and harder to solder without practice.
