Various WonderSwan tools by Dekadence

Dekadence Console Tools

A Rust rewrite is in progress. The Python versions will be removed once the rewrite is complete.

Various tools and code for WonderSwan related things. The tools have been used in the following demos:

• "Ihmesorsa" by Dekadence (WonderSwan) (YouTube, Pouet)
• "Rakointro" by Dekadence (WonderSwan) (YouTube, Pouet)
• "Vesilintu" by Dekadence (WonderSwan Color) (YouTube, Pouet)
• "Bar Frog Tux" by Dekadence (PC Engine) (YouTube, Pouet)

Requirements

• Install pipenv
• Install dependencies: pipenv install

wschecksum

Generates a checksum for a WonderSwan ROM. No real validation is performed, so be careful.

pipenv run python3 wschecksum.py INPUT_FILE

Note that this will overwrite the original file.

convert_mod

Converts an Amiga MOD to a format compatible with Dekadence's WonderSwan player. More to come.

pipenv run python3 convert_mod.py [--debug] INPUT_MOD OUTPUT_FILE

Use --debug to print the converter's interpretation of the MOD.

convert_tiles

Converts a PNG file to a tile map. Two files are created: a file containing the tileset, and a file containing the tile map. Images with up to four colors are supported, and both width and height must be divisible by 8.

pipenv run python3 convert_tiles.py INPUT_PNG

wonderswan-tools's Issues

Rewrite `wschecksum` in Rust

Initial work has been done in #9, so this shouldn't be too hard.

Rewrite `convert_tiles` in Rust

Initial work has been done in #9, so this shouldn't be too hard.
