# Worms?: license and credits

**The original game**: Worms?, Copyright (C) 1983 David S. Maynard, published by Electronic Arts for
the Atari 8-bit computers and the Commodore 64. The Commodore 64 version is by David S. Maynard and
Steven Hayes. Maynard released the Forth source code of both versions; Kay Savetz published it,
from the original floppy disks, at https://github.com/savetz/worms under the MIT license:

The game's data (the worm trail characters, the cursor pictures and masks, the note table, the
texts) is in its source and is copied from there into `src/data.ts`.

**This port** (`src/`, `test/`, `re/worms/`, `protocol/games/worms.capnp` and the server module
`server/.../games/worms/` in this repository) is a translation of that source by the freegames
project, under the same MIT license (the notice above). The online play is new in this port.

**The character set** (`assets/chargen.bin`): the program copies the Commodore 64's character ROM,
which is Commodore's. In its place the port uses the free C64-compatible character set of the MEGA65
Open ROMs (https://github.com/MEGA65/open-roms, `bin/chargen_openroms.rom`, its first 2 KiB
unchanged), Copyright (C) 2019 Paul Gardner-Stephen, 2019-2021 Roman Standzikowski (FeralChild64),
under the GNU Lesser General Public License, version 3 or (at your option) any later version
(https://www.gnu.org/licenses/lgpl-3.0.html). `re/worms/fetch.sh` downloads it and writes the file.

**Other parts**: the colours are Philip "Pepto" Timmermann's "Colodore" palette of the VIC-II. The
tests run the original on a 6502 core (`test/cpu6502.ts`) written for this repository's Pinball
Construction Set port, under the same MIT license as this port, and rebuild the Forth system under
the game on the model of fig-FORTH 1.1 for the 6502 (W. F. Ragsdale, Forth Interest Group, public
domain).

## Favicon

The favicon of the game's page (`web/icons/worms.png`, 48x48, and `web/icons/worms-180.png`, 180x180; drawn by `web/scripts/icons.py`) is the freegames project's own drawing and uses no art of the game: the letter "W" in DejaVu Sans Bold on a green rounded square. It is under the website's license (GPL-3.0-or-later, `web/LICENSE.md`). The DejaVu fonts' license lets images made with them be used freely.
