Since there has been confusion in the past over the order of
initialization and other such things, here it is, all spelled out
as of January, 2008:main()- does platform-specific init- calls mame_execute() [mame.c]mame_execute() [mame.c]- calls mame_validitychecks() [validity.c] to perform validity checks on all compiled drivers- begins resource tracking (level 1)- calls create_machine [mame.c] to initialize the running_machine structure- calls init_machine() [mame.c]init_machine() [mame.c]- calls fileio_init() [fileio.c] to initialize file I/O info- calls config_init() [config.c] to initialize configuration system- calls input_init() [input.c] to initialize the input system- calls output_init() [output.c] to initialize the output system- calls state_init() [state.c] to initialize save state system- calls state_save_allow_registration() [state.c] to allow registrations- calls palette_init() [palette.c] to initialize palette system- calls render_init() [render.c] to initialize the rendering system- calls ui_init() [ui.c] to initialize the user interface- calls generic_machine_init() [machine/generic.c] to initialize generic machine structures- calls generic_video_init() [video/generic.c] to initialize generic video structures- calls generic_sound_init() [audio/generic.c] to initialize generic sound structures- calls timer_init() [timer.c] to reset the timer system- calls osd_init() [osdepend.h] to do platform-specific initialization- calls input_port_init() [inptport.c] to set up the input ports- calls rom_init() [romload.c] to load the game's ROMs- calls memory_init() [memory.c] to process the game's memory maps- calls watchdog_init() [watchdog.c] to initialize the watchdog system- calls the driver's DRIVER_INIT callback- calls device_list_start() [devintrf.c] to start any devices- calls video_init() [video.c] to start the video system- calls tilemap_init() [tilemap.c] to start the tilemap system- calls crosshair_init() [crsshair.c] to configure the crosshairs- calls sound_init() [sound.c] to start the audio system- calls debugger_init() [debugger.c] to set up the debugger- calls the driver's MACHINE_START, SOUND_START, and VIDEO_START callbacks- calls cheat_init() [cheat.c] to initialize the cheat system- calls image_init() [image.c] to initialize the image system- calls config_load_settings() [config.c] to load the configuration file- calls nvram_load [machine/generic.c] to load NVRAM- calls ui_display_startup_screens() [ui.c] to display the the startup screens- begins resource tracking (level 2)- calls soft_reset() [mame.c] to reset all systems-------------------( at this point, we're up and running )----------------------- calls scheduler->timeslice() [schedule.c] over and over until we exit- ends resource tracking (level 2), freeing all auto_mallocs and timers- calls the nvram_save() [machine/generic.c] to save NVRAM- calls config_save_settings() [config.c] to save the game's configuration- calls all registered exit routines [mame.c]- ends resource tracking (level 1), freeing all auto_mallocs and timers- exits the program
