The Flatpak RetroArch's folder at 000 hid the retroarch.cfg naming ~/Games/bios, and the run offered 6.6 GB to ~/.config/retroarch/system. A closed folder under HOME or above the default now leaves no default: --dest is asked for. Python 3.14's quiet Path.exists() refusals are told from absence by os.stat, and an assumed folder reads as the one a frontend usually reads.
The hint bar, the help and the install's stop line read RETROBIOS_PAD:
gptokeyb, evmapy, muxterm and miyoo each name their own buttons and
none they lack. A desktop names keys only, SteamOS game mode and any
unknown run keep both names. On a Miyoo, A (Space) chooses, L1 and R1
page, and R2 goes back: B is Left Ctrl, which sends no byte alone.
SIGTERM and SIGHUP are handled from the start of the run, so a stop
during detection ends on the farewell. A closed window now ends with
129: once the last write fails, stdout and stderr point at /dev/null
and the flush at exit no longer turns the code into 120.
