Crisp Game Lib (Vircon32) - licence and credits
================================================================

Source: https://github.com/joyrider3774/crisp-game-lib-portable_vircon32, commit 9c18ea52e4c60b0fd631ffdeb4a0dab6f12f3194.
A cartridge with 266 small games by ABA Games (Kenta Cho, abagames), ported to the Vircon32 by Willems Davy
(joyrider3774) on top of his Tufty2350 port of crisp-game-lib-portable. The games come from three MIT-licensed
repositories of ABA Games: crisp-game-lib-games (https://github.com/abagames/crisp-game-lib-games),
crisp-game-lib-11-games (https://github.com/abagames/crisp-game-lib-11-games) and claude-one-button-game-creation
(https://github.com/abagames/claude-one-button-game-creation); the engine is crisp-game-lib
(https://github.com/abagames/crisp-game-lib) and its portable C rewrite crisp-game-lib-portable
(https://github.com/abagames/crisp-game-lib-portable), also MIT. The repository's LICENSE.txt is the MIT License of ABA
Games, "carried over unchanged" to cover this port's code (README of the repository). The cartridge has no image or
sound files from anyone: the graphics are drawn with rectangles and a built-in font, and sounds and music are generated by the
program. The only data file is a one-cycle sawtooth wave (2048 samples, a straight ramp) used by the small library
PlayNote (MIT, written for this port, libs/PlayNote/README.md); its README says the ramp was taken from the wavetable set of
VirconSynthesizer, and we checked that the file is byte for byte the straight ramp from -9000 to 9000 that any program
generates. The cartridge was built by FredyGames from this source with the official Vircon32 toolchain, unchanged.
