switch-probe — love-nx hardware probe

NOT FOR RELEASE. This package is a developer-only diagnostic for Nintendo Switch (love-nx). Do not ship it inside game.love or release NRO payloads.

Purpose

Validate Phase 0 runtime facts on OLED hardware before running the full Gen1Recomp launcher:

• love.system.getOS() (expect NX on Switch)
• Window dimensions (love.graphics.getDimensions())
• Save directory path (love.filesystem.getSaveDirectory())
• Gamepad / joystick / touch event logging

Fields shown on screen

Field	Source
OS name	love.system.getOS()
Dimensions	love.graphics.getDimensions()
Save directory	love.filesystem.getSaveDirectory()
love._os	Engine boot hint (when available)
Event log	Last 24 gamepad*, joystick*, touch* events

Build .love (from repo root)

(cd tools/switch-probe && zip -9 -r ../../.bazinga/work/switch-probe.love main.lua conf.lua)

Or:

mkdir -p .bazinga/work
zip -9 -j .bazinga/work/switch-probe.love tools/switch-probe/main.lua tools/switch-probe/conf.lua

Deploy beside gen1recomp.nro (loose mode) per docs/switch-development.md, renaming to game.love only for a probe run — use a separate SD folder so probe and game builds do not mix.

Desktop smoke (optional)

love tools/switch-probe

Expect desktop getOS(); input events appear when using keyboard/gamepad/touch (if available).
