Store all savedata in one zip-file for each ROM

[cyperghost]

Hello again,

there was a small discussion how to get multi-user support with savegamestates. Out of this I see a method to extract and to create zip files for all savestates that were created by the game itself (battery sav, srm...) or libretro (autosaves... romname.auto.state, romname.state?...)

First we need to install zip support

sudo apt install zip

I tested these batchfiles and they are working flawless

Add this to runcommand-onend.sh

#!/bin/bash
# Merge Savegames of called ROM in one zip file
# cyperghost 08/22/2017

rompath="${3%/*}"
romname="${3##*/}"
data="${3##*.}"
cd "$rompath" && zip --exclude=*.$data* -mj "savestates_${romname%.*}.ZiP" "${romname%.*}".* 

Add this to runcommand-onstart.sh

#!/bin/bash
# Extract Savegames of called ROM out of zip file
# cyperghost 08/22/2017

rompath="${3%/*}"
romname="${3##*/}"
cd "$rompath" && unzip -qq -o "savestates_${romname%.*}.ZiP"

So for ex. Terranigma with 1 SRM and 3 Autostates (in total 15MB) will merge to just 0,4MB ;)

---

As small bonus the files are named savestates_ROMNAME.ZiP so all savegames are listed by letter s ;)

Out if this: May I can get help with the exclude command? I solved it ... but I'm not satisfied with that! I read out ROMs filesuffix and exclude it. The ROMNAME itself won't work!

I used parameters rompath and romname just as hint what happens by using zip and unzip as self explaining variables. The bash files can be merged to one liners... on a later state :D

PS: The community is great!
