BD Emulator usage in arcade (speculation, discussion, notes)
There are several details that points to #BDemu_Drive_Format 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#XMB_Configuration_Files XMB configuration file for game column used by arcades is XMB-Game#update_files.2Fdev_flash.2Fvsh.2Fresource.2Fexplore.2Fxmb.2Fcategory_game_tool2.xml category_game_tool2.xm 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 PARAM.SFO#CATEGORY 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
