Answers H1's first half with a negative, and decodes what the timing constants are for. C_PAD_DECODER's +0xB4/+0xB8 and +0xBC/+0xC0 (10 and 90, twice) are not a key-repeat delay/interval pair. They are two identical channels of a DOUBLE-TAP detector, on cfg +0x74 (LT) and +0x70 (LB), firing output bits 0x20 and 0x40. The mechanism, from the image: both timers tick down once per update; a press arms the short timer to 10; a RELEASE adds 1000 to it as a flag stored inside the counter, which is why the tick watches for exactly 1000 and clears both there; a second press while the flag is set arms the long timer to 90; and while the long timer runs the output bit is asserted on EVERY update, with the short timer re-armed to 1010 each time. So it is a latch, not a repeat: a double-tap opens a 90-update window and the bit is held for its whole duration. That is a dash or barrel-roll shape, which fits the buttons it is wired to. H1: the directions have NO timer. The D-pad and left stick reach the output word through bare mask tests -- the four left-stick literals at 0x8220C458, C474, C490, C4AC, and DPAD DOWN through cfg +0xA4 -- with no counter loaded, decremented or tested on any of those paths. On the evidence of this layer a held direction does not repeat. Reach: one layer. A menu could implement repeat on top of a held bit, and this says nothing about that -- but it does establish the repeat is not in the shared decoder, so it would have to be per-screen. "One step per deflection" stays authored for the port; this narrows rather than settles. Refutation of my own earlier note that a decoder "is where a game normally puts its repeat timing, its edge detection and its button remap": remap survives, edge detection survives, repeat timing is REFUTED. That clause was a prior about how games are written, not a reading of this one. Also commits tools/ppc-dis, the minimal PowerPC disassembler this corpus has been rebuilding in scratch and losing to container restarts three times in one session.
