DC26-6502 (Brainf--k Interpreter NES Cartridge)
A brainf--k interpreter written for NES cartridge to be played on real NES hardware.
DC26-6502 was created by Vi Grey and is licensed under the BSD 2-Clause License.
This NES game is an interpreter for the brainf--k programming language, a programming language that uses only 8 symbols. The standard NES controller is used to create and run programs using only the power of the NES hardware CPU.
- asm6 (You'll probably have to build asm6 from source. Make sure the asm6 binary is named asm and that the binary is executable and accessible in your PATH. The source code can be found at http://3dscapture.com/NES/asm6.zip or in the included directory resources/asm6.zip)
Build NES ROM:
From a terminal, go to the the main directory of this project (the directory this README.md file exists in), you can then build the NES ROM with the following command.
The resulting NES ROM will be located at bin/dc26-6502.nes and should have the SHA-256 hash of
Cleaning Build Environment:
If you used
make to build the NES ROM, you can run the following command to clean up the build environment.
$ make clean

Unzipping the ROM:
The compiled NES ROM file at bin/dc26-6502.nes will also be a functioning ZIP file that contains 2 files, bfinterpreter.py and ascii2bf.py.
Interpreting the ROM:
This NES ROM is also a functional brainf--k file. Using
python3 bfinterpreter.py dc26-6502.neswill allow you to interpret the brainf--k file content of the NES ROM.
Creating Brainf--k Programs:
An included tool, ascii2bf.py allows you to create a brainf--k program for any file that is a multiple of 8 bits long. To create a brainf--k program, use
python3 ascii2bf.py filenamewhere filename is the path to the file you want to create a brainf--k program for.
This NES ROM runs as an NROM-256 ROM, but can also work as an NROM-128 ROM.
