"""The gap report reads the collection the way the resolver does.
|
|
|
|
Three ways it called held files missing, or a missing file held: system IDs
|
|
compared verbatim (sega-megacd against sega-mega-cd), no sha256 in the hash
|
|
fallback (rust_dos names its SC-55 ROMs by sha256 alone), and directory names
|
|
indexed as files (BasiliskII's required ROM read as held because cpcemu keeps
|
|
a directory called ROM).
