Control characters from names, folders and the installer's own text
are shown as ?, on screen and in the lines left after it. The terminal
mode and the signal handlers come back even when the last write fails
or a second signal arrives. A stop from outside hands the terminal
back, the second Ctrl-C is announced, speed reads the last seconds,
values are glued to their options, and counts read before a change of
options say so.
A bare install at a terminal of 40x12 or more opens a full screen that a
keyboard or a controller mapped to keys drives: setup, plan, install in
three presses, systems, regions, cores, game data, folder browser and a
dry-run preview one press away. The installer runs itself as a child with
--events for every check and install, the file list fetched once and
handed over with --manifest. --tui asks for it, --plain, RETROBIOS_PLAIN
and ACCESSIBLE keep the line questions.
Removed 7 test files (135 tests) fully covered by test_e2e.py.
The E2E creates all fixtures in setUp, exercises every code path
with real files and real functions. Single source of regression.
