Game card is a standard MMC card. Pinout is different, however it complies with MMC card.

There are two types of gc, one for retail and one for QA.

Partitions

Game card can be accessed with SceSdif module. It has the following partitions:

code type name desc
0x9 exfat gro0 Game Card
0xD raw Some data

Card initialization

Card initialization consists of two steps:

  • Standard MMC initialization.
  • Custom CMD56 initialization.

CMD56 is a command that is used to transfer vendor specific data from host to card and back to host.

Second step is crucial and is required to be done before host tries to read any data from the card for example with CMD17.

Standard MMC initialization

This step is performed by SceSdif.

Part1: Card identification (SD, MMC, SDIO)

  • 40 00 00 00 00 95 - CMD0 - GO_IDLE_STATE
  • 48 00 00 01 AA 87 - CMD8 - SEND_IF_COND
  • 45 00 00 00 00 5B - CMD5 - IO_SEND_OP_COND
  • 77 00 00 00 00 65 - CMD55 - APP_CMD

Part2: Card initialization

  • 40 00 00 00 00 95 - CMD0 - GO_IDLE_STATE
  • 41 40 FF 80 00 0B - CMD1 - SEND_OP_COND
  • 42 00 00 00 00 4D - CMD2 - ALL_SEND_CID
  • 43 00 01 00 00 7F - CMD3 - SET_RELATIVE_ADDR
  • 49 00 01 00 00 F1 - CMD9 - SEND_CSD
  • 47 00 01 00 00 DD - CMD7 - SELECT_CARD
  • 46 03 AF 01 00 43 - CMD6 - SWITCH (ERASE_GROUP_DEF)
  • 48 00 00 00 00 C3 - CMD8 - SEND_EXT_CSD
  • 50 00 00 02 00 15 - CMD16 - SET_BLOCKLEN
  • 46 03 B9 01 00 2F - CMD6 - SWITCH (HS_TIMING)
  • 46 03 B7 01 00 2D - CMD6 - SWITCH (BUS_WIDTH 4)

Custom CMD56 initialization

CMD56 initialization is performed by SceSblGcAuthMgr.

SceSblGcAuthMgr uses SceSblSsSmComm API to call gcauthmgr_sm function 0x1000B that is a wrapper for Kirk services 0x1B-0x20.

Game card can be accessed with SceSdif device index 1.

Initialization consists of 20 packets total. There are 10 request and 10 response packets. Each packet is sent or received with CMD56.

  • 78 00 00 00 00 25 - CMD56 (REQUEST)
  • 78 00 00 00 01 37 - CMD56 (RESPONSE)
