jzIntv browser player / GPL-2.0-or-later
Upstream port: https://github.com/onykage/jzintv-wasm
Revision: 6322350da2ff139cd64ddcb6f9ae451b1651420d
Original emulator: Joe Zbiciak and contributors. See COPYRIGHT.txt.

Toolchain: Emscripten 4.0.20. Extract corresponding-source.tar.gz.
Activate emsdk, then from jzintv/:
  mkdir -p ../bin
  emmake make -f Makefile.emscripten -j2 build
The result is ../bin/jzintv.js and ../bin/jzintv.wasm.

Local changes: no firmware preload; the Intellivoice mask data is removed
from source and loaded from /system/IVOICE.bin (2048 bytes, zero-padded).
Owner Executive, Graphics, ECS and Voice files are external and excluded
from the corresponding sources. Controller state and the ECS keyboard
use the emulator's existing pad/action tables. Pause yields without
advancing the emulation; audio has a gain stage and a bounded queue.
The only supported SDL1 display mode is 0 (320x200x32).

The player module and archive helper are included under integration/.
The site's existing FreeIntv player and its saves are separate.
