SaveStateManager - a script to delete your savestates

[cyperghost]

Rewrite to v2

Get it here - via github

RetroPie-UserMenu-SaveStateManager

SaveStateManager - This will let you delete determinated SaveStates of choosen ROM-file via runcommand UserMenu

To install:

Use this single installer

wget -O - https://raw.githubusercontent.com/crcerror/RetroPie-UserMenu-SaveStateManager/master/install.sh | bash

To use the script run your ROM:

1. If the grey runcommandbox apperas, press a controller button
2. Access UserMenu and run SaveStateManger
3. Now delete your SaveStates you are fed off with B-Button
4. To have some extra options go to Extended Menu (extended version)
5. To Backup the current selected file (blue row) select Backup file

Picture Gallery

**Extended + Light version++

Select the flavour you want (extended or light version)

Select deselect the save states you want to work on (B-Button) and select EXTRA-MENU

Extended Menu available

BACKUP SRM file

Select SRM savestate and go to Extended Menu (or Backup Menu in light version)

Selected file (blue row) will be saved (or the Extended Menu will be shown if it's a state-file)

Delete Files

Select deselect the save states you want to delete (B-Button) and select OK

You will be asked for delete!

Have much fun and now there is also annother use for the USER MENU
Greetings fly out to @meleu @hiulit @obsidianspider @pjft @Hex @mediamogul @jonnykesh @Rion @all I have forget!

This code is intendet to be improved as it is a bit bare written (much better then the SaveStateChecker as it made use of functions and less if-clauses ;)

But I need some help with the exit codes and the return to the main menu...

Updated to version 1.31

Troubleshooting

Updated script to v1.22

28.01.2018

v1.22 is a bug fixed 1.21, the detection of the rom and srm pathes is improved, due missing response and as I'm using updated RetroPie versions since 4.0.2 some config files got a massiv change! So if the first character of the path_string is / then it's a valid path.

Hello fellows,

I'm (a bit) proud to introduce the SaveStateManager script. As I created the SaveStateChecker all requirement were there to write also a Manager script.

The script is best called with the famous User Menu that was introduced by BuZz. To get the script working we need just to parse system = $1 and rom = $3 to it. Then we have a nice selection of all Savestates (also the autosaves) and the SRM-files (the battery save) and we can delete them.

To install:

1. Get the script from the box below and place it to a space were no man has gone before maybe /home/pi/RetroPie/scripts/SaveStateManager.sh
   1.1 You can use command from 1.2 to directly download from github to desired location
   1.2 wget http://raw.githubusercontent.com/crcerror/RetroPie-UserMenu-SaveStateManager/master/SaveStateManager.sh -O /home/pi/RetroPie/scripts/SaveStateManager.sh
2. We make the script executable with chmod +x /home/pi/RetroPie/scripts/SaveStateManager.sh
3. We create a small script in /opt/retropie/configs/all/runcommand-menu/SaveStateManager.sh
   3.1 We just make a small one liner /home/pi/RetroPie/scripts/SaveStateManager.sh "$3" all
   3.2 You see $3 is placed first in quotes, after this allrepresents the system. We can also use $1
4. To use the script run your ROM
5. Now if the grey box apperas, press a controller button
6. Access UserMenu and run SaveStateManger
7. Now delete your SaveStates you are fed off
   IN THIS VERSION THERE IS NO ROM DISPLAYED!!
   The pictures show a recent version (1.2??) but the look is equal to current 1.31

1. Rewrite of code for better array handling (thx @meleu for his rpi-art)
2. Dialogs are now working as they should
3. Dialogs can now launch the ROM or bring you back to runcommand or ES
4. Deleted savefiles will fade out of list
5. Better Detection of SRM filestates
6. Nice countdown if you try to launch a ROM

Picture Gallery

1. I want to try to delete an Automatic generated save file

2. I am asked if I really want to delete this file

3. As you see, the entry is faded away and can't be selected anymore

4. Now lets try to delete the SaveState Slot 10

5. Here I'm also asked to erase this file

6. Voilá the entry for SaveState Slot 10 is past now

Now some greetings to people ;)

@cyperghost
Looks good, I think that it should automatically filter the ROM files out, if you have a giant set of ROMs, that would be a LOT of scrolling.

[PokeEngineer]

@cyperghost

Awesome work!

[mitu]

@madmodder123 I think the script works in the context of launching a ROM, through the Runcommand user menu, so it only shows the save states and ram saves for the ROM you're currently playing, not for all ROMs that have save states.
@cyperghost Nice work !
One suggestion though - maybe remove the option to delete the ROM ? Since the script is geared towards managing save states and it doesn't allow the deletion of the ROM anyway, wouldn't be better to just not have this option at all ?

[cyperghost]

@mitu
You can't delete a ROM. You will need to change the script for doing this. It shows the ROM caused by status_array=("$status_path/$rom_no_ext."*) Then I check how much entries are in. If it's only one (Just ROM-name or empty) it will abort. Otherwise I had to check every entry for file extension.
I know only one situation it can happen. That would be PSX. Because you have 2 files. An image (BIN, IMG) and a CUE. So you might can delete the IMG or BIN.

All in all you are right. It shows just states of currently loaded ROM and this is the intention that you can only call it via USER MENU.

But @madmodder123 is right. It's no problem to extend this and search system-wide for savestates. This script then should be nested into RetroPie-Menu. There is a codepiece here in the forum that I've once written to make a system wide selection possible. :)

[mitu]

@cyperghost said in SaveStateManager - a script to delete your savestates:

("$status_path/$rom_no_ext."*)

I don't have the PI right now to test, but would it work if you changed it to

("$status_path/$rom_no_ext."{state*,srm,auto})

This should select based on ROM basename and the list of extensions in the accolades.

@mitu I created v1.21 (this disables the ROM file and shows only SRM and STATES (also Autosaves!)
But I prefer the older version....

@mitu said in SaveStateManager - a script to delete your savestates:

("$status_path/$rom_no_ext."*)

I don't have the PI right now to test, but would it work if you changed it to
("$status_path/$rom_no_ext."{state*,srm,auto})

This should select based on ROM basename and the list of extensions in the accolades.

So I'm at home and I can explain a bit more.
If you assign state* and srm to the array mask then there are two possibilites. The file is located there and assigned (good!) There is no file and then it will be just located as character into the array! So you have to find ways to prove if the file is valid. I did that with the testcommand -f in v1.21

In 1.20 I just ask for ROMName without extension then it's clear what happens! I find the ROMName and all savestates and possible the SRM state within just one loop. If the array contains only 1 entry it's just the rom-name itself. Therefore I check the arrays if the last character is * if yes then it's just an empty entry.

I think v1.21 is more specialiced to really find SaveStates and SRM files
1.20 is a bit more bare but seems to be better prepared for more usecases.
If I get more feedback I can improve this script. But for now both versions work fine!
