Here it is!

RetroPie Limit Last Played Games v2.0.0

Read the new docs, as there have been a few changes.

Added

Option to install/Uninstall the script from EmulationStation's RetroPie menu.
GUI mode.
Debug mode - To test the script. No harm will done to the gamelists ;)
Log files - Found in /home/pi/Retropie-Limit-Last-Played-Games/logs).

Fixed

Uncommented code preventing to actually remove 'last played' games.
Fixed #1 - Only show systems that have a gamelist.xml.

Changed

Refactored the code to create backups. Now the folder is called gamelist-backups (inside the $SYSTEM_ROMS folder) and contains all the game lists backups, named [DATE]-gamelist-backup.xml.
Added more error/success output messages.
Better control of what games have to be processed.

Examples

./retropie-limit-last-played-games.sh --nth 25 --systems

This will set the number of 'last played' games to limit at 25 and then it will show a dialog from where it can be selected as many systems as needed.

./retropie-limit-last-played-games.sh --nth 25 --systems --debug

This will set the debug mode on. It's perfect for testing the script before actually 'harming' the gamelists.

./retropie-limit-last-played-games.sh --gui

This will start the GUI. It will ask you to enter a number to limit the number of 'last played' the games shown. Then it will ask you to choose the desired systems to apply that limit.

Options

--help: Print the help message and exit.
--install: Install the script in EmulationStation's RetroPie menu.
--uninstall: Uninstall the script from EmulationStation's RetroPie menu.
--nth: Set number of 'last played' games to limit per system (10 by default).
--systems: Show dialog to select systems to limit.
--gui: Start the GUI.
--debug: Set debug mode to test the script.
--version: Show script version.

@hiulit Great work! (without having tested it)

@hiulit, first, thank you so much for your work, your work is really appreciated.
Second, yout script is awesome, it's working perfectly.
Installed the script on the Retropie menu, launched the script, choosed to keep 1 last played game, at the end of the execution you need to restart Emulationstation to see the results.

Now my last played list contain only 40 games, one per system :)

Thank you again, you did a great job.

@hiulit I don't want to do a PR but you can add these lines to perform a restart. You can write a small yes/no dialog to perform a restart to ES.

# Restart ES!
touch /tmp/es-restart
chown pi:pi /tmp/es-restart
kill $(pidof emulationstation)

Best wishes ;)

hiulit

@madhorse Hey! You're welcome! I'm glad you find it useful :D

And you made a good point about EmulationStation having to be restarted to see the changes. I'll add a message to the script .

hiulit

@cyperghost hey, I was just thinking about adding a message but I like your idea better. Thanks for the code ;)

hiulit

@cyperghost btw, can this code be run under 'sudo'? Because my script has an option be installed in the RetroPie menu and I think the scripts executed from there are run under 'sudo'.

cyperghost

@hiulit Yes but then the file has to be chowend to pi:pi
Added to the codebox

hiulit

@cyperghost the file being 'tmp/es-restart' or my script?

cyperghost

@hiulit The restart file
Because ES entitiy deletes the file on restart and if it was created by root it won't work

hiulit

@cyperghost got it. Thanks! I'll try it ;)

@hiulit I've found a little "bug", if there are more games that have the exactly same lastplayed it will give you this errore:

Number of 'last played' games to limit is set to '1'.

psx
---
'gamelist.xml' for 'psx' found!
> Creating 'gamelist-backups.xml' for 'psx' ...
'gamelist-backups.xml' for 'psx' created successfully!
./retropie-limit-last-played-games.sh: line 124: [[: 0

./retropie-limit-last-played-games.sh: line 124: [[: 0
1: syntax error in expression (error token is "1")
No 'last played' games to remove.

All done!

After i change the time, i just add 1 second, everything is working without a problem.
I think it's almost impossible to have more games with the same lastplayed date and time unless someone manually edit the file and make some mistakes, so probably is not a big deal.

hiulit

@madhorse Hmmm... I'll take a look at it. But what are the odds of having the same date on different lastplayed tags? How is it even possible to open 2 different games at the same time? :P hehe! Anyway, I'll look into it.

Exactly, in fact i manually edited the gamelist.xml to add some games because i didn't want to scrape it, copy and paste the <game> section and then changed the name and the path, by doing this i also duplicated the lastplayed date and time.
I just pointed out because if someone needs help for the error

./retropie-limit-last-played-games.sh: line 124: [[: 0
1: syntax error in expression (error token is "1")

you know why, but i don't think you need to spend much time over this problem.

hiulit

@madhorse I figured it out. I'll test it a bit and I'll upload a new version. It would be cool if you could help me test once this fix is uploaded. I'll let you know. Thanks!

P.S. This will be on Wednesday. Tomorrow is a holiday for me :P

MadHorse

@hiulit No problem mate, I will be happy to test the new version.
Thank you and happy holiday :)

Version 2.1.0 of RetroPie Limit Last Played Games is here!

Added

Dialog asking if the user wants to restart EmulationStation when the script is done.
Output message for the games that will be shown in the 'last played' section.

Fixed

When there are duplicated <lastplayed> tags in different games the script crashes. Now, if the scripts find duplicates, it looks for the game's name (it should be different).

Thanks to @cyperghost for the restart function and @MadHorse for testing the script.

Updated the documentation for v2.1.0 - 2018-09-12 in the first post.
