@MortalWombat said in Tips on insuring that RetroPie will save battery games & Metadata changes?:

Is there anyway to search the results?? Hopefully by searching just "autosave" or "interval"??

You can use ctrl-w to search within the document while it's open in nano.

@mitu I read through that thread and I can't seem to figure out if they agreed that it was a core problem or a retroarch problem. In either case it seems that the problem was never addressed.

I thought that save states would be a good workaround but that doesn't solve the problem of having to disk swap between game areas. not to mention, the save states are named after the disks rather than the m3u file so any save after the first one made must be renamed in order to be used.

is there a way to force the core into naming the save state a certain way?

edit: I'm an idiot. loading creates new disk drives to the index. you just need to pick the proper index slot, hit insert and that's that. arggagahha

@gdi Ignore the ingame Retroarch menu for saving. Just save the game how you would do it like it was an actual Playstation. Should work just fine.

@usarmyvet Please provide more details - which games, what's the error message, what emulator ? Are the permissions on the ROM folders correct - can you write in the folder as the pi user ?

@mitu perfect, seems easy enough!
Thanks for your help!

@Mr.-Waffles It seems to be a known bug: https://github.com/libretro/RetroArch/issues/4820

There's a workaround that you can try here: https://github.com/libretro/RetroArch/issues/4820#issuecomment-294326479

@retroaceson And I think they'll answer something like "We already implemented the undo savestate/loadstate feature". You can see it at Quick Menu.

@nialithe My best guess is the permissions are messed up on your rom directories (this can happen if you copy roms/folders as root). The simplest way to fix is to run the following from from the RetroPie_Setup script: C Configuration / Tools -> 821 resetromsdir. This will fix permissions and you should be able to save. Another possibility is that you disk is full, but you'd likely see other problems if this were the case.

@briandamico i dont know the name of your controller but its config file will be located in /opt/retropie/configs/all/retroarch/autoconfig/ .
