cartreader/sd

Copy these files to the root of your SD card. If you're on Linux or MAC make sure the Windows style line endings(CRLF) don't get removed.

Hint: You can select all the databases, right-click, properties, mark checkbox Hidden and now they won't show up in the Cart Reader's file browser.

gb.txt / md.txt / pce.txt / sms.txt

These files store the ROM names and the CRC32 checksums.

Example:
007 - The World Is Not Enough (USA, Europe).gbc
E038E666

Name
CRC32

gba.txt

This file stores the GBA database which is needed because the save type and rom size are not stored inside the rom.

Example:
007 - Everything or Nothing (USA, Europe) (En,Fr,De).gba
9D4F1E18,BJBE,08,1

Name
CRC32, game id, size in MByte, savetype

Savetypes:
0 = Unknown or no save
1 = 4k Eeprom
2 = 64K Eeprom
3 = 256K Sram
4 = 512K Flash
5 = 1024K Flash
6 = 512K Sram

n64.txt

This file stores the N64 database which is needed because the save type and rom size are not stored inside the rom.
The CRC32 checksum is used to verify a good dump.

Example:
007 - The World Is Not Enough (Europe) (En,Fr,De).z64
002C3B2A,3B941695,32,0

Name
CRC32, ROM internal CRC1, size in MByte, savetype

Savetypes:
0 = no save chip
1 = SRAM
4 = Flashram
5 = 4K Eeprom
6 = 16K Eeprom

nes.txt

This file stores the iNES Header, the CRC32 of the first 512 bytes after the iNES header and the CRC32 of the complete ROM minus the iNES header.

Example:
89 Dennou Kyuusei Uranai (Japan).nes
BA58ED29,716956B4,4E45531A100010080000070700000001

Name
CRC32 (prg+chr combined), CRC32 (512 bytes), iNES Header

snes.txt

This file is needed for odd sized SNES games like Final Fantasy (JAP), Super Metroid(US/JAP) or Tales of Symphonia. Without this file you will get overdumps and the checksum calculation will fail.

Example:
'96 Zenkoku Koukou Soccer Senshuken (Japan).sfc
05FBB855,70DE,12,048

Name
CRC32, internal checksum, size in Mbit, number of banks (lorom needs twice as many banks as hirom for the same rom size, lorom: 32kb banks, hirom: 64kb banks)

snes_clk.txt

Calibration data for clock generator.
