BD Emulator usage in arcade (speculation, discussion, notes)

There are several details that points to BD emulator functions in arcade machines:

• Arcades doesnt have a BD drive, but the game column in XMB in arcades has an "item" to mount discs, this is not a mistake and they did not foget to remove it, is there on purpose
  • The .xml XMB configuration file for game column used by arcades is category_game_tool2.xml and the items displayed are under the tag View id="root_arcade" the item that mounts the disc is "seg_device" by using CB_MEDIA_FORMAT_PS3GAME_BD

• The path used by firmware updates, the path used by game updates, and the subfolder names used by them matches with a disc structure... but this "disc image" is stored in HDD
  • Firmware updates in /dev_hdd0/game/SCEEXE000/ARCDIR/PS3UPDAT.PUP and game updates in /dev_hdd0/game/SCEEXE000/ARCDIR/INSDIR/DATA000.PKG, the root of the disc is the folder SCEEXE000 (possibly containing a PS3_DISC.SFB, the folder ARCDIR is "replacing" the standard folder name "PS3_GAME" used in discs. ARCDIR can contain a PARAM.SFO and several subfolders (LICDIR, USRDIR, INSDIR etc...). All this keeps the standards of documented disc structures, but there can be some parameters inside the .SFB or any of the .SFO's specific for "arcade game disc images"

• Autoboot of games (when PS3 is turned on) in arcades is simply the same XMB setting in retail ps3's used for "disc autoboot"
  • In xRegistry.sys the entry: /setting/system/powerOnDiscBoot, the only difference is in arcade the disc is an image mounted automatically by BD emulator
