First, load the Intellivision system ROMs

The Intellivision can't switch on without the two ROM chips Mattel built into it: every game runs on the EXEC and draws with the GROM's characters. They are still under copyright, so they aren't included here: choose or drop your own ROM image files. They stay in this browser and are never sent anywhere. The browser remembers them, so you only need to do this once.

• Executive ROM (EXEC) Required

  The console's operating system. Exactly 8 KB (8,192 bytes); Mattel's has the CRC-32 checksum CBCE86F7.

  Often named exec.bin or exec.rom

• Graphics ROM (GROM) Required

  The 256 built-in characters and shapes. Exactly 2 KB (2,048 bytes); Mattel's has the CRC-32 checksum 683A4158.

  Often named grom.bin or grom.rom

• Intellivoice ROM Optional

  The speech chip in Mattel's Intellivoice module, for the few games that talk (B-17 Bomber, Space Spartans, Bomb Squad, TRON Solar Sailer...). Exactly 2 KB (2,048 bytes); Mattel's has the CRC-32 checksum 0DE7579D. Without it, those games play without speech.

  Often named ivoice.bin, IVOICE.BIN, sp0256-012.bin or IntelliVoice BIOS (1981) (Mattel).int

Pick the files at once, or a .zip containing them (MAME's intv.zip works). These are not games: once the console is on, cartridge images (.rom, .bin, .int) go in the cartridge slot below the screen.
