507 * C Button R/L/D/U, Mempak/Rumblepak switch, X/Y Axis, AnalogDeadzone, AnalogPeak.
508 *
509 * The N64 controller configuration behavior is regulated by the 'mode' parameter. If this parameter is
510 * 0 (Fully Manual), then all configuration data is loaded and parsed without changes or autoconfig from
511 * the configuration section. Any errors or warnings are printed. If the mode parameter is 1 (Auto with
512 * named SDL Device), then the code below searches through the available SDL joysticks for one which
513 * matches with the 'name' parameter in the config section. If a match is found, then the corresponding
514 * autoconfig is loaded and the regular parameters from the config section are updated with the
515 * autoconfig'ed settings. If the mode parameter is 2 (Fully Auto), then the code below searches through
516 * all available detected SDL joysticks to try and find an autoconfig for each. If an autoconfig match is
517 * found, then it is loaded and all config parameters (including device, name, and the regular parameters)
518 * are updated.
519 *
520 * This function is called with bPreConfig=true from the PluginStartup() function. The purpose of this
521 * call is to load the 4 configuration sections with autoconfig data if necessary for a GUI front-end.
522 * When we are called with bPreConfig=true, we should only print warning/error messages and not info/status.
523 * This function is also called right before running the ROM game from InitiateControllers() with
524 * bPreConfig=false. We should only print informational messages here, because we do not want to duplicate
525 * console output with the console-ui front-end (since the PluginStart() and InitiateControllers()
526 * functions are called in quick sequence from the console-ui).
