SRL::Input::Gun Struct Reference

Detailed Description

Light gun peripheral.

Note

Light gun only works if SRL_FRAMERATE is set to 2 or higher (>30fps)

Light gun can NOT be connected through multi-tap! It must be connected directly to the console. Only valid ports are port 0 and port 6.

Light gun should be calibrated in game, to ensure correct positional data. Calibration should be done by user and result preferably stored to backup memory.
