The emulated accelerometer had its own axes (x right, y along the pointer, z out of the button face) where KPAD's are x left, y out of the button face, z along the pointer ((0, -1, 0) held level, KPADReset), which the game then remaps (WPadAcceleration::update). A level controller read as a remote standing on end: the surfing coach's "Point your Wii Remote at the screen" never passed, and the Star Ball would roll forward at full speed. - wpad.cpp adds gravity in KPAD's axes. While the game steers by tilt (port_input_use_tilt), it follows the right controller pitched up by the game's neutral angle, so a level controller gives the grip the game asks for; a controller whose orientation is unknown counts as level. PortPadState carries which way is down from the controller (xr_app.cpp) and, as accelerations, only the motion on top (shakes). - Star Ball: neutral 80 degrees (90 - sCoreBaseDegreeYZ), not 100. Its tutorial reads the tilt only while it checks that the remote is raised, so aiming near the sign never counts as a shake. - PETARI_INPUT scripts tilt the controller with PITCH= and ROLL=. - docs/CONTROLS.md: the in-game instructions in controller terms.
