Neko Project II kai (github.com/AZO234/NP2kai, rev 5939e0c), built for the browser by ReCompile with Emscripten (web/build_wasm.py; ReCompile patches: emu/pc98/patch_np2kai.py). The core and its parts are under these licenses. NP2kai’s optional GPL parts are not in this build: the DOSBox FPU (fpemul_dosbox*.c: SUPPORT_FPU_DOSBOX/SUPPORT_FPU_DOSBOX2 not defined; the SoftFloat3 FPU is used) and the MAME OPL/ADPCM code (sound/mame: USE_MAME_BSD selects the BSD versions). fmgen (FM sound) by cisc is free for non-commercial use with attribution (fmgen_readme). No BIOS ROM is included: NP2kai’s own BIOS emulation runs instead.
