"""A file in another emulator's tree does not answer for this one.
|
|
|
|
bios/Other/<emulator>/ holds what that emulator ships. The path step took a
|
|
shortened tail that only NetherSX2's tree answered as proof for EmuCoreX's
|
|
unlock.wav, and broke a full-tail tie between EmuCoreX's GameIndex.yaml and
|
|
the system directory's copy by index order, serving a fork's game database
|

to upstream PCSX2.
