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.
exports/ now holds the twelve platforms' own files, corrected, with a
report of every change, read by the site's corrected files page. Two
summaries are reworded for the page: an addition the format cannot
carry is counted as left out, and RetroPie names each skipped package
by sentence instead of joining reasons with semicolons. Its parser no
longer reads "e.g" as a file name.
