BPS Famicom Tetris Disassembly

Work in progress

Build Requirements

• gcc
• make
• cc65
• python (with pillow library)

Disassemble

Requires a backup of the original game with the filename clean.nes in the project root directory.

main.asm is dynamically generated using main.infofile. To update, add label information to main.infofile and run make disassembly. This will update main.asm with the new labels as well as run make compare to validate the new main.asm produces the expected result.

Build

make

This will ouput a file tetris.nes with the following:

sha1sum: 218dbaa3827650c9ad9917f41f2d886aeb688c58
md5sum: e986b2e5202e16c480241a5c866f4bb2

Validate

make compare
