The page named the entries a change touched and never the values, so
a maintainer could not check a correction. The report now carries
changes, one object per change with kind, entry, field, old and new,
read from the platform entry and from the value the render writes
(written() per format: record value for System.dat and RomM, one md5
where a single one is checked). The existing label lists are derived
from it. The page writes "md5 X becomes Y" and names each required
flag with its new value. A test parses the original and updated
System.dat and es_bios.xml and checks the list equals the diff.
The rom line renderer upper-cased every crc, so Dinothawr.zip's
683ed4ad, the one lower-case crc libretro writes, changed with no
correction behind it. A line whose values match ours now keeps its
bytes, a corrected crc follows the case of its own line, and an added
line keeps the file's upper case. An empty truth hands System.dat back
byte for byte for RetroArch and Lakka.
libretro titles each section with the system as it spells it,
"Commodore - Amiga". An addition for a system it has no section for
opened one under our slug: 21 sections came out as commodore-c64,
quake, laseractive or xrick, which no libretro DAT carries. An addition
now lands only in a section the original holds and is otherwise counted
as left out, so the export keeps the original's 66 sections. A platform
entry is always written, under its own section.
RomM kept hashes the truth contradicts beside the corrected one, RetroDECK kept a cleared md5, Recalbox counted changes on an element it writes back whole, and two record formats counted fills no record could hold.
libretro indents 39 rom lines of System.dat with spaces. The export
read tab-indented lines only, so those left the base and came back
re-rendered at the end of their section, and one our transcription
lacked would have been deleted. Any indentation is read and kept.
Run ruff check --fix: remove unused imports (F401), fix f-strings
without placeholders (F541), remove unused variables (F841), fix
duplicate dict key (F601).
Run isort --profile black: normalize import ordering across all files.
Run ruff format: apply consistent formatting (black-compatible) to
all 58 Python files.
3 intentional E402 remain (imports after require_yaml() must execute
after yaml is available).
