playlist lost when disk is full after game is started about retroarch HOT 2 OPEN

If you have a full disk, you'll likely have lots of issues using your machine, let alone RetroArch. What is causing your disk to fill up?

from retroarch.

needed to free up an SD card, so i mounted it and copied the roms on it to the device as root (on linux, root can access the entire storage, but regular users only 95% or so).
therefore i didnt notice that i was above the "disk full for regular user quota".

most other programs are wellbehaving when ENOSPC happens - they just display an error message and stop the task they were about to do.

but really, this question appears odd as we're in rom land, where the full USA PSX romset already takes > 1 TERABYTE. many users use a dedicated rpi for retroarch, and afaik it supports only microsds up to 256gb.

btw it gets better than the above - if you exit retroarch while there's no space available and have "save settings on exit" ticked, then your entire retroarch.cfg gets wiped too. the sane thing to do before any overwrite is to atomically rename the old file to .bak or whatever, then write the new file, and if it fails move the old file back and display a notice. that would also be helpful if you try to do a savestate while the disk is full, rather than failing silently (i havent tested that yet but i'd guess that's what happens).
