Both cores ask for the system directory. emucv never reads the answer back, and eightyone serves every ROM from its embedded table and only writes zxpand-eeprom.bin there. The reasons were in their notes, not in the exclusion_note the fileless audit accepts as an answer.

exclusion_note: >
|
|
The system directory holds eightyone/ROMs, FDCs and IDEs, but every ROM the
|
|
core requests is served from its embedded table before any path is opened
|
|
(libretro/eo_roms.cpp:106-128). The one file it touches there is
|
|
zxpand-eeprom.bin, written when absent (81/Source/zxpand/smbsd.cpp:75-98).
|
|
notes: |
|
|
Recalbox port of EightyOne, vendored under 81/ and built with CMake.

The ROM directory is <system>/eightyone/ with ROMs/, FDCs/ and IDEs/
|
|
subfolders.

ref: libretro/libretro_core.cpp:2620-2631
|
|
|
|
86 machine, interface, IDE, graphics and speech ROMs are compiled in as
|
|
zlib-compressed arrays and looked up by basename.

|
|
memory_load, memoryLoadToAddress and font_load query the embedded table
|
|
before opening any path, and every ROM name the core requests is in that
|
|
table, so no ROM is read from the system directory.

Didaktik D40/D80 tests for eightyone/FDCs/didaktik.gama.rom and stores its
|
|
full path in CurRom when present; memory_load reduces the path to its
|
|
basename and serves the embedded copy.

ZXpand writes zxpand-eeprom.bin (256 bytes of 0xFF) under the ROM
