Two runtime-side changes the launcher's SYSTEM row needs.
The row was hidden whenever the linked BIOS was bundled, on the reasoning
that there was nothing to select. With OpenBIOS AND a retail image linked
that strands the player: choosing retail — and clearing back — is exactly
what the row is for. Visibility now asks the registry (is any linked
backend NOT the bundled one?) via psx_bios_has_selectable(), which is
also correct before selection, unlike psx_bios_image.
A BIOS named in settings.toml is likewise now honoured on every build.
It was previously ignored on bundled builds to stop a stale path pointing
at a foreign image, but that guard would now silently discard the only
in-app way to opt into retail. The identity gate is the real protection,
and it explains a mismatch rather than ignoring it. An EMPTY value stays
meaningful in the other direction: that is the launcher's Clear, "go back
to the bundled BIOS", so it is not adopted as a path.
Pairs with recomp-ui feat/bios-row-clear.
Not yet compile-verified against the launcher: building with
PSX_RECOMP_UI=ON on this branch fails in the recomp-ui netplay callback
ABI (main.cpp:4495), which traces to 87491cb and is inherited from this
branch's base predating master's matching integration — the same skew
that stops MMX4/MMX5 building on current master with their pinned
recomp-ui. Needs master merged in, which this branch requires before
merge regardless.
