If you have an Atari 2600 game console or a compatible one (for example, Rambo), you can make a home-made cartridge for it with the home-made game Bran, o constructor (Bran, the builder), using the advice of the author of Instructables under the nickname DiegoD57. But this homemade will not work with later Atari Flashback series consoles where cartridge connection is not possible.
The prototype of the game’s character was Brandon Stark from Game of Thrones. By controlling Bran with the joystick, you have to help him in the construction of the wall and battles with the King of the night.
Writing games for the Atari 2600 is best done in assembly language, but the master prefers BASIC. There is a ready-made bundle from the Stella emulator, the batari Basic compiler and the Visual batari Basic shell. It all looks like this:
The result of compiling a BASIC program uses space in ROM less efficiently than the same program written in assembler. To compensate for this, I had to make the graphics too minimalistic even for the Atari 2600:
The source code of the program lies here, he commented in some detail in Portuguese.
The wizard downloads Gerber files from and makes a cartridge board. Now he will have to program a type 2732 ROM chip. Parallel ROM programmers are quite rare these days, like such chips themselves. The wizard acquires the TL866 model programmer, which is still on sale, and uploads the firmware (the binary file is here):
In addition to the board and ROM, he takes the 7404 chip (K155LN1) and a ceramic capacitor with a capacity of 0.1 μF (designation on the case - 104):
After the board, the master takes on the case. STL files developed by Thingiverse author under the nickname joegrand, he takes here (CC-BY 3.0). Prints:
It turns out like this:
As you can see, the master does not have a very accurate 3D printer, so the embossed logo had to be removed. The modified STL file is here. It remains to make a sticker using this site. Yes, yes, a special site for preparing stickers for cartridges for Atari 2600. The wizard fills in the fields on the page, starts the generation of stickers, prints, pastes, and you're done:
You can put the cartridge in the console and play:
In the absence of a 3D printer, the wizard advises taking the case from a damaged cartridge. But if you do not have the original Atari 2600, but its Rambo clone, then you most likely do not have such cartridges, since this console has many games flashed into the built-in ROM, and its owners did not seek to purchase additional cartridges. Often, cartridges for it were not brought into commercial tents of the early nineties at all, knowing that there would be no demand.The slot at Rambo is usually valid, and when you install a cartridge in it, the internal ROM is disabled.
