The branch's evidence was captured on an older MAME binary whose frames
were VR150 (1024x864). Rebuild MAME from this tree's driver and re-run
verify.sh --skip-mame at the VR319 default (1280x1024 active).
All six tests pass. Event counts, focus=00400001, tick=887 and quit=1
are unchanged; only the main-loop counts moved with the frame cadence:
move 650, panels 648, quit 555 (was 354/346/300). The evidence PNGs are
regenerated at 1280x1024. Record the numbers and the geometry change in
VT1200.md, TERMTRIS_REPORT.md and HANDOFF.md, and note the qemu-i386
toolchain fallback.
The r5.01 tools are 16-bit OS/2 NE programs. A Linux kernel built
without CONFIG_X86_16BIT (this box's cloud kernel) rejects modify_ldt
for 16-bit segments, so lx_loader aborts at its first segment even
though it is a 32-bit binary. Probe for that failure and use
qemu-i386, whose linux-user modify_ldt supports 16-bit segments.
LX_RUNNER overrides the choice. The toolchain output is unchanged:
the build completes in ~10 s and the COFF differs only in its header
timestamp.
