Copy these files to the root of your SD card.

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:
A22J,08,3
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:
002c3b2a,NO7P,32,0
CRC32, game id, size in MByte, savetype

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

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. There are still a lot games missing from this list.

Example:
A172,24,48
checksum, size in Mbit, number of banks (lorom needs twice as many banks as hirom for the same rom size)

hirom64.map

This is a Nintendo Power mapping file that changes the mapping to a single 4MB HiRom game with 64Kbit/8KByte save. The first byte is used to specify the mapping.

Bit0-1 SRAM Size (0=2K, 1=8K, 2=32K, 3=None) ;ie. 2K SHL (N2)
Bit2-4 ROM Size (0=512K, 2=1.5M, 5=3M, 7=4M) ;ie. 512K(N+1)
Bit5 Zero (maybe MSB of ROM Size for carts with three FLASH chips) (set for HIROM:ALL)
Bit6-7 Mode (0=Lorom, 1=Hirom, 2=Forced HIROM:MENU, 3=Forced HIROM:ALL)

Example:
0x5d = 0b 01 0 111 01
01 -> Hirom
0
111 -> 4M
01 -> 8K

lorom256.map

This is a Nintendo Power mapping file that changes the mapping to a single 4MB LoRom game with 256Kbit/32 KByte save.

Example:
0x1e = 0b 00 0 111 10
00 -> Lorom
0
0b111 -> 7 -> 4M
0x10 -> 2 ->32k
