playstation (redump) readme

Every game image in new/ comes from (playstation) redump (archive.org).

Repack Redump zips to 7z:
for zip in *.zip; do bn="${zip%.zip}"; mkdir "$bn"; cd "$bn"; arch_unpack ../"${zip}" && rm ../"${zip}"; cd ..; arch_pack "${bn}.7z" "$bn" && rm -rf "$bn"; done | tee /home/lucifer/zip_2_7z_log.txt

***

Extract playstation 2 zips, and organize extracted files/directories:
recursive_extract .; find . -type f -iname "*.iso" -exec mv -n -t . {} +; find . -type d -empty -exec rm -rf {} +

***

Strip $session numbers from directory names:
regex[session]='^(.*)(-[[:digit:]]+){2}$'
for fn_in in *; do if [[ ! -d $fn_in ]]; then continue; fi; if [[ $fn_in =~ ${regex[session]} ]]; then fn_out="${BASH_REMATCH[1]}"; echo "$fn_out"; fi; done

for fn_in in *; do if [[ ! -d $fn_in ]]; then continue; fi; if [[ $fn_in =~ ${regex[session]} ]]; then fn_out="${BASH_REMATCH[1]}"; echo "$fn_out"; mv -n "$fn_in" "$fn_out"; fi; done

Find duplicates:
declare -A roms
regex[disc]='\(Disc [[:digit:]]+\)'
for fn_in in *; do fn_out="${fn_in%%(*}"; if [[ -z ${roms[${fn_out}]} ]]; then roms["${fn_out}"]=1; elif [[ $fn_in =~ ${regex[disc]} ]]; then true; else echo "$fn_out"; fi; done

***

Redump naming scheme:
'(Rev 1)' seems to be the identical release to '(v1.1)'
'(Rev 2)' seems to be the identical release to '(v1.2)'
etc.
