#### gba.txt
2017-02-11 16:28:16 +01:00
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
2016-07-04 13:21:34 +02:00
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
2018-05-07 11:02:05 +02:00
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. This list was generated by a simple script and might contain many errors.
2016-07-04 13:21:34 +02:00
Example:
A172,24,48
2018-07-23 14:59:18 +02:00
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)

#### PCE_CRC_LIST.txt
Placing this file into the root of the SD card will enable verify and automatic game name identifier.

#### hirom64.map
2017-10-13 19:52:44 +02:00
This is a Nintendo Power SF Memory 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.
2016-07-04 13:21:34 +02:00
Bit0-1 SRAM Size (0=2K, 1=8K, 2=32K, 3=None) ;ie. 2K SHL (N*2)
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)
More info: http://problemkaputt.de/fullsnes.htm#snescartnintendopowerflashcard
Example:
0x5d = 0b 01 0 111 01
01 -> Hirom
0
111 -> 4M
01 -> 8K

#### lorom256.map
2017-10-13 19:52:44 +02:00
This is a Nintendo Power SF Memory mapping file that changes the mapping to a single 4MB LoRom game with 256Kbit/32 KByte save.
2016-07-04 13:21:34 +02:00
Example:
0x1e = 0b 00 0 111 10
00 -> Lorom
0
0b111 -> 7 -> 4M
0x10 -> 2 ->32k

#### mbc5.map
This is a Nintendo Power GB Memory mapping file that changes the mapping to a single 1MB MBC5 game with 32 KByte save.
GB Mapping Info (by skaman)
Entries start at 0x0 divided into 3 Byte segments
For example, let's look at the start of the mapping for a multi-game cart:
A8 00 00 71 04 00 48 94 04 separates into
A8 00 00 MENU
71 04 00 GAME 1
48 94 04 GAME 2
Byte 00 of each entry contains the MBC Type, ROM Size, and SRAM Size (start).
SRAM Size is 3 bits across Byte 00 and Byte 01.
MBC SZE SRAM
A8 = 101 010 00 0 MBC5, size 2 = 128KB
71 = 011 100 01 0 MBC3, size 4 = 512KB, SRAM 8KB
48 = 010 010 00 1 MBC2, size 2 = 128KB, SRAM MBC2
Byte 00: 1st 3 Bits = MBC Type
000 = MBC0
001 = MBC1
010 = MBC2
011 = MBC3
101 = MBC5
Byte 00: 2nd 3 Bits = ROM Size (minimum size is 128KB due to block size)
010 = Size 2 - 128KB
011 = Size 3 - 256KB
100 = Size 4 - 512KB
101 = Size 5 - 1MB
Byte 00: Last 2 Bits (bit1..bit0) + Byte 01: 1st Bit (bit7) = SRAM Size
00 0 = NONE
00 1 = SRAM MBC2
01 0 = SRAM 8KB
01 1 = SRAM 32KB
Byte 01 contains the SRAM Size (end) and ROM Block in the Flash.
ROM Blocks are 128KB (8 total)
Byte 01: Last 7 Bits (bit6..bit0) = ROM Block
00 = ROM Block 0 start offset 0KB
04 = ROM Block 1 start offset 128KB
08 = ROM Block 2 start offset 256KB
0C = ROM Block 3 start offset 384KB
10 = ROM Block 4 start offset 512KB
14 = ROM Block 5 start offset 640KB
18 = ROM Block 6 start offset 768KB
1C = ROM Block 7 start offset 896KB
Byte 02 contains the RAM Block in the SRAM.
RAM Blocks are 8KB (16 total)
Byte 02: RAM Block:
00 = RAM Block 0 start offset 0KB
04 = RAM Block 1 start offset 8KB
08 = RAM Block 2 start offset 16KB
0C = RAM Block 3 start offset 24KB
and so on until RAM Block 15.
Going back to our example cart:
A8 00 00 MENU: MBC5, size 2 = 128KB, ROM Block 0, RAM Block 0 (Ignored since SRAM is 000)
71 04 00 GAME 1: MBC3, size 4 = 512KB, SRAM 8KB, ROM Block 1, RAM Block 0
48 94 04 GAME 2: MBC2, size 2 = 128KB, SRAM MBC2, ROM Block 5, RAM Block 1
