Controller-only machines (Steam Deck) had no way to open or navigate the F10 options overlay -- it was keyboard+mouse only. Now: - Select (BACK) rising edge toggles the overlay, tracked across both the open and closed poll paths (padSelectPrev) so a held button cannot re-toggle on the transition. BACK is read nowhere else in the port. - While open, D-pad or left stick up/down moves the selection, A/X step forward (the Enter equivalent), B/Y step back, Start closes. The gamepad bits are OR-ed into the existing keyboard edge logic, so repeat/clamp/ scroll behaviour is identical; input.c already swallows pad 0 while the overlay is open, so nothing reaches the game. - inputPadButton/inputPadAxis accessors expose raw SDL pad state to the overlay (unaffected by our logic-layer swallow). Smoke-tested headless with GE_OPTIONSOVERLAY=1 and no pad attached.
