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.
Why no files
The system directory is asked for and stored in retro_base_directory, which is named in no other file of the tree and read nowhere: the answer is never used (libretro.cpp:28,60-63).
