Sony - PlayStation Memory Card - 24 PCS PS & PS2 Memory Card with Case 7 PCS SONY Playstation 8MB SCPH-1020 & SCPH-10020 - Video game

Playstation SCPH-1020

Since the ROM media is now a disk, game save data is stored on an external storage device, a memory card (128 KB capacity; the notation is 1 Mbit). When the PS is started up without inserting PS standard software, the user can move, copy, and delete data from the memory card by going to the memory card management screen. The version released in each country is region-free. Data access is performed in units of sectors (128 bytes) via synchronous serial communication through the controller port. The read speed is 10KB/sec and write speed is slower.

The size of saved data is managed in units of “blocks” (8 KB worth), and up to 15 blocks can be stored per memory card. Although the actual number of blocks available is 16, one block is used to manage the 15 blocks used to store save data [Note 11], and the management data is read when the memory card is loaded to check the contents during save and load operations, The management data is read when the memory card is loaded to check the contents for saving, loading, etc., and functions to allow the unused area to be recognized and overwritten in the process of identifying and deleting saved data titles stored in the block.

The number of blocks used varies depending on the game title (as indicated on the package), and a minimum of one game and a maximum of 15 games of game data can be saved. Since some titles reserve multiple blocks at once and others reserve blocks sequentially by data creation, the number of game titles that can be saved may be reduced due to an increase in the number of blocks used for a single game title or a shortage of free blocks to reserve blocks at once. Many players bought two or three more cards instead of one.

The save data is no longer saved in battery backup format, which means that the save data is no longer lost when the battery runs out in the console or cassette. It is no longer necessary to transfer the data to other media and replace the battery to prevent the loss of saved data when the battery runs out. Saved game titles can now be deleted from the main unit management screen even if the user does not own the saved game title. However, if the saved data has been deleted from the memory card menu due to an operational error, the data can be restored by pressing L1, L2, R1, and R2 simultaneously before performing any other operation.


Playstation2 SCPH-10020

An auxiliary storage device for storing saved data of PS2 games, it is almost the same size and shape as the PS memory card, but unlike the PS memory card, it has a more angular shape. However, to differentiate it from the PS memory card, “PlayStation 2 8MB” is printed on it.

The appearance is almost the same, but the notch on the insertion side of the memory card is different, making it physically impossible to insert the card into the memory card slot of the PS main unit even if it is attempted.

Compared to the PS memory card (128 KB), the new memory card has a larger capacity, eliminates the block system, speeds up memory card reading and writing, and incorporates Sony's copyright protection technology, Magic Gate.

It is possible to add a flag to the saved data itself to restrict copying (some moves are possible, others are not); it can also be used with the PS3 memory card adapter.
