Licensing: 100% open source

This emulator uses only open source components: DOSBox 0.74 (GPL-2.0) compiled to WebAssembly + js-dos 6.22 (MIT) as loader. No proprietary MS-DOS ROMs required — DOSBox implements its own DOS-compatible shell. Any commercial software you run is your responsibility (use only shareware/freeware/software you legally own).
