2ksbox stands on the work of many people who gave their code away. Every
machine runs on QEMU, the Voodoo 2 is 86Box’s, the music comes from
emulators of the original sound chips, and the CRT look is the libretro community’s. Thank you, all of you.
Every component the app ships, and its licence, is listed in
THIRD-PARTY-NOTICES.md.
