        "notes": "Intellivision emulator by Joe Zbiciak, published as dated archives on\nthe author's site rather than a public repository. Profiled from\njzintv-20200712-src.zip (release notes for SVN r2110). RetroPie builds\nthat archive from its own mirror (scriptmodules/emulators/jzintv.sh).\nRetroBat ships jzintv.exe from the official jzintv-20200712-win32-sdl1.zip,\nbyte for byte (sha1 e666df50), which reports SVN revision 2108.\n\nThe EXEC, GROM and ECS names default to exec.bin, grom.bin and ecs.bin\n(cfg/cfg.c:625-628) and are overridden by -e, -g and -E\n(cfg/cfg.c:687-689). Each is opened through path_fopen on the ROM search\npath, built from --rom-path, then JZINTV_ROM_PATH, then DEFAULT_ROM_PATH\n(cfg/cfg.c:870, 917-920), which is the current directory and ../rom on\nWindows and Linux (config.h:239, 288). RetroPie passes\n--rom-path=$biosdir. RetroBat passes the full path of exec.bin and\ngrom.bin in its bios folder with -e and -g, refuses to start when either\nis missing, and adds -E with ecs.bin only when the jzintv_useECS option\nis set and the file exists (emulatorLauncher/Generators/Jzintv.Generator.cs).\n\nNo hash is checked on any of the three images. The read length is the\nonly gate, and the size of exec.bin picks the machine: 8192 bytes is the\noriginal EXEC, 8704 bytes the Intellivision II EXEC2 with its extra 256\nwords at $0400, 16384 bytes the INTV88 / TutorVision WBEXEC\n(cfg/cfg.c:1114-1150).\n\nThe Intellivoice SP0256-012 mask ROM is compiled in (ivoice/ivoice.c:511,\n1958). ivoice_init also tries sp0256_0.bin to sp0256_F.bin in the current\ndirectory for extra speech ROM pages (ivoice/ivoice.c:1498-1539,\n2005-2012). No released hardware needs one, and a missing page is\nskipped silently.\n\nPalette files (--gfx-palette, cfg/cfg.c:965-985) and keyboard hack files\n(--kbdhackfile, cfg/cfg.c:135-140) are user configuration. RetroBat\nwrites its own keyboard hack file from the controller mapping. Cartridge\nmetadata is matched against a compiled-in table by CRC32 of the game\n(cfg/cfg.c:1280-1295).\n",
