Technical notes

Discrete Integrated Circuit Emulator. Emulates early arcade hardware built from discrete logic components with no CPU. Libretro port by Ken Mitton, based on upstream DICE by Adam B.

Games load as MAME-style ZIP archives matched by CRC32 per ROM chip (chips/rom.cpp:41-218). ROM-less games (Pong, Breakout, etc.) use .dmy dummy launcher files. The system directory is retrieved but never used for file loading (libretro.cpp:60-62).

No BIOS or firmware files required. Generated on 2026-03-25T14:56:43Z
