Converting or utilising OpenEMU Save State files

[soren42]

I've been using OpenEMU on macOS for some time now, and am just now converting to RetroPie. Are OpenEMU's .oesavestate files readable by RetroPie? Or does a format converter exist?

(Now that I've really dug into it myself, I've realised that the .oesavestate files are macOS bundles. However, digging in, there's a file within named State that I'm hoping will be the portable portion of the bundle.)

Does anyone have experience with this?

I've googled around, checked the subreddits for both RetroPie and OpenEMU, and browsed the available issues on Github — and found nothing helpful. (I suppose if no one can give me a definitive answer, my next step will be to open both save state formats and see what I can uncover.)

if you rename the State file to <gamefilename>.state and place it in the roms folder for that system, you can try your luck.

Not sure if you managed to sort this, but I have just managed to transfer save files from OpenEmu to Retropie successfully.

You can only transfer battery saves though (.sav) which means only games which allow you to save in game.

You cannot transfer OpenEmu save states (.oesavestate) as far as I can tell.

To transfer battery saves, copy and paste the .sav file into your retropie ROM folder, ensure the name is the same as the ROM, then change the file to .srm (literally just type it).

Example:

OpenEmu battery save: Earthbound.sav
Retropie battery save: Eathbound.srm

Once you’ve done that, restart emulation station, load your rom, and your save game will automatically be there.

Appreciate this is an old post, but I’ve just spent the last 2 days trying to figure this out and just managed it by trial and error.

Enjoy.
