Plain-language explanation of the reply-latch wedge for non-technical pod owners, linked from the firmware README top. Frames the bug as a 'busy' sticky note the board forgets to take down on the give-up path, and how RIO 4.3 fixes it. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

# Why your pod's stick sometimes "died" mid-battle — and why it won't anymore
|
|
|
|
*A plain-language explanation for pod owners. The technical write-up is in
|
|
[RIOv4_2-ANALYSIS.md](RIOv4_2-ANALYSIS.md).*
|
|
|
|
Inside every pod is a small computer board from 1994 (the **RIO**) whose job
|
|
is to tell the game what you're doing: which buttons you pressed, and where
|
|
you've moved the stick, throttle, and pedals.
|
|
|
|
The board and the game talk like two people on walkie-talkies. Every time the
|
|
board reports your stick position, it waits for the game to answer *"got it."*
|
|
During calm flying that works fine. But in a frantic firefight — lamps
|
|
flashing, buttons hammering — the channel gets crowded, and once in a while
|
|
that little *"got it"* gets drowned out.
|
|
|
|
When that happens, the board repeats itself a few times and then, sensibly,
|
|
gives up and moves on. Here's the bug: while it's sending a position report,
|
|
the board puts up a mental sticky note that says *"busy — already sending
|
|
one."* When a report goes through normally, it takes the note down. But on the
|
|
give-up path, the 1994 programmers forgot one line — **the note never comes
|
|
down.** From that moment the board looks at the sticky note, decides it's still
|
|
busy, and quietly throws away every stick and throttle update forever after.
|
|
|
|
That's the "wedge" you may have felt: mid-mission, your stick and throttle
|
|
just stop doing anything, while the buttons and lamps still work fine —
|
|
because those travel a different path that the sticky note doesn't block.
|
|
Starting a new mission always cured it, since a new game tells the board to
|
|
clean house, sticky note included.
|
|
|
|
The **RIO 4.3** firmware adds the one missing instruction: whenever the board
|
|
gives up on a report, it now takes the sticky note down too. We stress-tested
|
|
it by mashing buttons at over nine presses *per second* for two minutes
|
|
straight — the old board wedged under that abuse; the new one never misses a
|
|
beat.
