This module allows reading and editing puzzles for the Game Boy game Mario's Picross.

marios_picross_puzzle_editor_gui.py provides a simple GUI for editing a Mario's Picross ROM to modify the puzzles. A Windows binary is available here.

Under the hood, the GUI uses mariospicross.py.

To parse a ROM for puzzles, use read_puzzles_from_rom:

with open("path/to/picross.gb", "rb") as romfile:
    data = romfile.read()
puzzles = mariospicross.read_puzzles_from_rom(data)

See the docstring on read_puzzles for the format of the parsed puzzles.

To insert puzzles back into a rom, use insert_puzzles

puzzles = [{...}] # whatever puzzles you've made
with open("path/to/picross.gb", "rb") as romfile:
    data = romfile.read()
newdata = mariospicross.insert_puzzles(data, puzzles)
with open("path/to/new_rom.gb", "wb") as romfile:
    romfile.write(newdata)

The new ROM should work anywhere the original would.
