sylph-decoder 6267245920 method: a truncating instrument, and an unreachable stop condition
The UI draw capture printed 8 vertices = two quads per draw, so a batched draw
dropped the rest silently. Four EXTRAS elements therefore appeared in no draw on
any screen, which reads as 'the game does not draw these' -- and the port spent
an iteration measuring them as the worst on the screen and asking about them.
When an instrument says an element never appears, check its limits before
believing the game.

And 'press down until the cursor stops moving' is not a stop condition on a
menu that WRAPS: it was unreachable, the loop only exited by exhausting its
budget, and it landed on EXTRAS because a dropped press cancelled one lap. An
earlier version of the same loop pressed (A) on NEW GAME after two identical
readings caused by a dropped press.

What held throughout is the part worth keeping: verify the state you measured,
never the actions you took.
