Help with making my own cart getting started

[GameboyReviewer]

Hey guys GBR here and I was wondering what do I need to put my own atari 2600 rom onto a cart? Like what things do I need? Plz and Thx

Well first you need to identify what mapper the game uses, and then you will need eprom chips to put the game onto.

Locatings the right donor cart for the mapper may be hard, or not possible because some games wont work with any available mapper.

Mapper? For a 2600 cart?

You mean bankswitch method. Then he needs an eprom programmer. and on and on and on.

I just assumed it was the same as a NES cart,

but I guess assuming is not a good way to go.

If the size of the ROM is 4K or 2K, no bankswitching would be needed. If you just want to build one cartridge, you could hack up an existing board to put your game on.

 

There's an incompatibility between commonly available EPROM's and the native 2600 chip interface methodology. This requires a single inverter gate to compensate. There are circuit boards available from the AtariAge store (used to be anyway) with provision for the inverter chip designed in.

 

And you'll need an EPROM programmer (AKA "burner"). And unless you get a big pile of empty chips and can afford to throw them away if you mess up, you'll want an EPROM eraser as well.
