Rclone-Sync-SaUCE

Use Rclone sync to shrink down some of the sauces to fit on a smaller USB drive.

Resauce the OnesaUCE with Rclone

These instructions are written for Windows but rclone sync works in other OSes too. I use Rclone-Sync-SaUCE to fit more systems on a smaller USB flash drive for my AtGames Legends Ultimate Arcade. This is written for One Sauce v2 but can be easily adjusted to work with other rom/emulator builds. Disclaimer: Rclone can delete and overwrite things so use this at your own risk.

TLDR: Basically create a Rclone filter list to use with rclone sync command to filter out roms and their associated artwork/videos.

1. Create a tempmain folder on your Windows PC. Create three folders: onesauce2, txt and old.
2. Put rclone.exe in the tempmain folder or install rclone so it can be executed anywhere.
3. Combine all onesauce version 2 downloads into onesauce2 folder
4. Output list of each rom pack. (Some of these filter txt files are included above in the txt folder) e.g.
   1. dir /B "onesauce2\content\retrofe\collections\Daphne\roms" > txt\daphne.txt
   2. dir /B "OneSauce2\content\retrofe\collections\Sony PSP Minis\roms\*.CSO" > txt\pspmini.txt
5. format lists according to https://rclone.org/filtering/ Use + or - at beginiing of each line to add or remove. Use ** to specify etc. e.g.
   1. - Commodore 64/**/5th Gear**
   2. + Commodore 64/**/720 Degrees**
   3. - Commodore 64/**/747 Flight Simulator**
6. Recommend installing vscode. vscode supports multi line edits and regex find and replace/delete. Hit CTRL-h to use find/replace.
7. Careful not to filter out system stuff like "cheats". Make sure your filter is focusing on rom filenames without the extensions.
8. Replace problematic characters like !, $, #, &, etc with ? or delete them if they are at end of filenames.
9. Remove rom extensions like .img then remove [], {}, and () with included text at the end of filenames.
   1. \s\([^)]*\) is a regex to find things in parentheses
   2. \s\[[^)]*\] is a regex to find things in square brackets

10. Edit base_to_flash.bat and collection_to_flash.bat to specify the correct flash directory. Replace <flash drive letter> with the correct flash drive letter in the batch files. WARNING: This will overwrite and delete things. Make sure you choose the right drive.
11. Use base_to_flash.bat to move your main files to your flash drive.
12. Use collection_to_flash.bat to move your rom files to your flash drive.
13. Check the log files to see if it looks right.
14. Remove --dry-run from the sync commands in the batch files when it seems like it's work right.
15. WizTree (or Windirstat) is great way to analyze the results

Rclone Gotchas:

• Have to use forward slashes most of the time
• Have to specify directory and use /**/ to catch multiple directories
• Have to search by rom extension to get real list of files
• -v --log-file=file.log to review what it did because output is large
• not excluded files not in source get removed in destination
• excluded files don't get removed in destination by default
• --delete-excluded forces excluded files to be removed in destination
• Filter lists are case sensitive
• !, &, $, #, etc. are bad so delete or replace with ?
• Rclone filters work top-down so...
• A short rom name like - Commodore Amiga/**/pac-man** might match more then you want so move it lower on the list.

Linux, iOS, Bash

You can easily get this to work in a Bash console. Convert the Batch files to work with Bash scripting instead. Just use cat instead of type, mv instead of move and change backslashes for directories to forward slashes.
