The script exporters (Batocera, ROCKNIX, KNULLI, AmberELEC, EmuELEC)
read the checker of the pinned original: when checkBios hands an
item's md5 to a function that tests it with isinstance(..., list),
as md5Matches does since batocera.linux 6b08b873, an entry whose
emulator code accepts several dumps is written with all of them, and
an addition that needed several becomes writable. Items with altmd5
keep a string, since checkBios wraps them in a list of its own.
No cached original reads lists today, so every export is unchanged.
The report records a list as a list, counts the lists written, and
records a list the truth extends without contradicting it.
batocera.linux 6b08b873 lets a biosFiles item declare its md5 as a
list of strings, and checkBios accepts a file matching any of them.
The scrapers join the values with commas, as for Recalbox, and record
md5_list so the export writes the list back as a list, byte for byte.
