64K Feature Audit
Every entry of chunk5's PatchTable (Apply64KPatchTable) redirects a
48K stub into a chunk3 routine when the game finds a language card. The
port never executes the patch table; chunk5Boot sets patched64K and
each patched call site chooses the chunk3 translation on that flag
(Has64K at $08C6 is forced to 1, mirroring the oracle's boot).

The regression scripts in port/tools/verify/regress.sh run with
64K mode on, so every hook above is exercised against the oracle
wherever a key script reaches it (ADF, reality mode, night lights,
crash, course plotter, demo, WW1 and the war report included).
