SaveStateCheck script

[cyperghost]

Updated to v1.10

This is a masive rewrite! And should work now with all versions of RetroPie.
You can now change style how the the stats are viewed!

1. via dialog windows
2. just a text list (I prefer this one)

Hello fellows,

I created a small script that checks your ROMs SaveStates during gamestart and shows how much gamestates were saved for your launchend ROM. If there is at least one savestate an AUTO Savestate or a SRM-file a small blue box will tell you.

SRM files are the battery saves. I created this because sometimes I can't remember if I used some savegames. So this script will

• Shows you the number of GameStates saves
• Which GameSlot is used
• Is there is an ingame save (SRM)

You need the script add to runcommand-onstart.sh and parse parameters to it.

1. Save the code from box below to a place you like maybe /home/pi/RetroPie/scripts/SaveStateCheck.sh
2. Make the script executable with chmod +x home/pi/RetroPie/scripts/SaveStateCheck.sh
3. Enter nano /opt/retropie/configs/all/runcommand-onstart.sh
4. Enter line /home/pi/RetroPie/scripts/SaveStateCheck.sh "$3" "$1" "light" "5"
   4.1 $3 = rompath parsed by runcommand MANDATORY!
   4.2 $1 = systemname (fba, gb...) parsed by runcommand you can also enter all MANDATORY!
   4.3 Choose between windows or light. This parameter can be left free then windows is default
   4.4 This number is sleepcommand to show the infobox or text for x seconds. Can also left blank then 3 seconds are default
5. If there is no gamesave the box/test won't show up

Greetings fly out to @meleu and @hiulit
This script can be optimized and is intendent to do so :D

Have fun and happy gaming!

Just forget one picture says more than 1000 words

Example picture of starting screen with Kid Icarus for GameBoy

So you see. The game gets one SRM savefile and my forst Gameslot is not 0 it's the 1 ;)
So you see it's always good to know where are your savestats and which slot they use ;)

Dialog Screen paresed by windowparameter

Text list via light parameter parsed

[lilbud]

I wish this could be shown in ES as a metadata field

[cyperghost]

@lilbud Well this is also possible but needs to add some flags to the each gamelists.xml and then it needs to be featured in ES and in each theme. So it isn't a task that can be done alone and in a 4 hours coding-straight.

Maybe it can be added in runcommand.shitself if buzz decides to do so. The advantage is it would look much sleeker.

Maybe @hiulit can do a rework - instead of a fun-fact screen it could be a savestat-fact screen ;) Who knows?

[lilbud]

@cyperghost Or maybe instead of tying into the splashscreen or runcommand, maybe a OSD message can pop up while Retroarch starts that says how many save are available for said game.

Something like: There are 3 save states for this game

[cyperghost]

@lilbud I see it more complex as ES is standalone and RetroArch is standalone. The creation of the save.state*-files is a task of RetroArch. I think it won't be a good idea to integrate ES much deeper into RetroArch.

You loose flexibility and independence if you rely on settings that are made by programm X to work with programm Y.

See... in my script I tried to make the determination of the pathes 100% save in case if it's the default state. It doesn't matter if the default is written deFault, DEFAULT, dEfAuLt... default as I set it to uppercase and compare the string with DEFAULTso it's always a match.

But this was an easy task .... in this case!
All in all it's very difficult to make every case water-proof ;)

[cyperghost]

Updated the script:

• now removes (...) and [...] in gamenames (a bit bare!)
• removed some typos
• if parameter for sleeptimer is missing, default timer will be set to 3 seconds
• rearanged the text itself a bit

Have fun!
Thanks for any feedback

Old version for archive - Awful piece of script!
Very complicated in a try to avoid function calls!

You should open a GitHub account and create repositories for your scripts there :D

[cyperghost]

@hiulit I have a github account ;)
Thanks for feedback
As I'm not a professional programmer I do coding just for fun. But my hope is that maybe you can improve this script.

I saw your coding style...
And I think you do coding professional or have a strong attitude to this ;)

[hiulit]

@cyperghost Well, what are you waiting for then! Create repositories for all your scripts! :D
Actually I am a programmer, but I'm also a noob at shell scripting, so we are all noobs ;)

[cyperghost]

@hiulit Here you are ;)

My best repo is the binary archive for old ES versions ;)
