I would like to share my RetroArch setup experience.
I have research on the YouTube and Google about the Cloud backup for RetroArch.
(Shared roms and shared saves and cloud backup)
1) Shared roms
I have place the Retro roms on the
/mnt/vendor/factory/roms. (Switch HOS root)
Then I can use the Switch RetroArch to play the rom (SD:/roms) on the Switch HOS.
And I can use the Android RetroArch to play the rom (/mnt/vendor/factory/roms) on the Android.
2) Shared saves
Both RetroArch have set the
saves and
savestates path to "/mnt/vendor/factory/sync/retroarch/save/" and "/mnt/vendor/factory/sync/retroarch/states/".
Then both RetroArch can shared the saves.
(The savestates is highly depended the same core and same retroarch version, it may not share to use with difference environment)
3) Cloud backup
I have install a "
Folder Sync" app on the Android,
And set the "/mnt/vendor/factory/sync/" folder to sync to my Google Drive,
(The main tricky part is the app interface cannot select the "/mnt/vendor/factory/sync/",
but I found that it can edit the config XML file to do it.
)
Then it can sync the save and savestate to the Google Drive for backup.
And I have setup the desktop RetroArch and Google Drive on my PC.
Then I can sync and play the save and savestate on my PC also.
