Pressing the Square button again restores the cubes and then deblurs them as the background becomes blurry. On earlier revisions, upon pressing the Square button on the System Configuration menu, the cubes on the left part of the screen become blurry, as the entire background deblurs, before they shrink. One very minor change between the BIOS versions on the PlayStation 2 models SCPH-39001 (and earlier) and SCPH-50001 (and later) is the way the cubes on the System Configuration menu behave when the Square button is pressed. This is corrected in BIOS versions 01.70 and later, where the Cancel sound is heard when backing out of the Time Options menu.īlurred Cubes On Display SCPH-39001 (v01.60) and earlier In BIOS versions 01.60 and earlier, the Confirm sound can be heard when backing out of the Time Options menu. In all later BIOS revisions, every instance of the word "Notation" was replaced with the word "Format". In PlayStation 2 models with BIOS version 01.10, "Time Notation" and "Date Notation" are used to identify the options for time and date formats respectively. The earlier Japanese models (with BIOS versions 01.00J through 01.10J) do not leave the red error screen when the eject button is pressed, but rather the only way to leave this screen is by using the Reset button. The word "disc" is also not capitalized on this screen starting on the 3xxxx consoles (but it still is on the browser screen). The text is centered differently between the two versions and the wording of the error is updated starting with the 3xxxx consoles. SCPH-1xxxx consoles use an older version of the red error screen. Version Differences Red Error Screen SCPH-1xxxx consoles It is possible to make an "invalid" system configuration file which would skip the nameless blue preset from being loaded, letting it display the unused red background that presumably would've been seen if something had gone horribly wrong with the file. The first two named ones have an unused red background and the 3rd unnamed preset has the regular dark blue background usually seen with the System Configuration file (as well as with Corrupted Data, Network Settings and other system files) which is used to override the red background. The OSDSYS executable has three icon.sys presets loaded at all times - Your System Configuration, あなたのシステム設定ファイル and a third nameless preset, all three pointing to the _SCE8 ( \ICOIMAGE\ICOBYSYS) BIOS icon.
#PS2 BIOS ROM REDDIT UPDATE#
Modern versions of Open PS2 Loader will update this play history as well.Ī list of available resolutions can be found in the TESTMODE executable file in the BIOS. When using HDDOSD, both disc and HDD titles will be recorded (however most unofficial uses of the HDD do not conform to the appropriate partition naming scheme required for this functionality). Only a limited number of titles can be recorded: if exceeded, the least recently played one will be dropped. This data is stored in the "B?DATA-SYSTEM" folder of the Memory Card, displayed in the Browser (using a ROM-builtin icon not actually stored on the card) as the misleadingly named "Your System Configuration": the actual system settings are stored in built-in EEPROM (and HDD system partitions for HDDOSD/PSBBN exclusive settings such as keyboard repeat rate). The "Sony Computer Entertainment" boot screen can show "towers" (blocks appearing in different numbers and different heights) in the background, as long as a PS2 memory card is inserted: while undocumented in the manual, these blocks represent the different titles launched on the system, and the respective number of launches with that memory card inserted. Somewhere around 00002BD0 in the BIOS 01.00 files is what appears to be a debug menu, containing the options: Verify that these entries actually are part of a menu.
