Header

Used as the template, as it provides enough information. The last 10 bytes of each ROM contain the following entries, 1 byte for each entry, except for the Checksum that takes 2 bytes.

Developer ID

0x01 = "Bandai"
0x02 = "Taito"
0x03 = "Tomy"
0x04 = "Koei"
0x05 = "Data East"
0x06 = "Asmik Ace"
0x07 = "Media Entertainment"
0x08 = "Nichibutsu"
0x0A = "Coconuts Japan"
0x0B = "Sammy"
0x0C = "Sunsoft"
0x0D = "Mebius"
0x0E = "Banpresto"
0x10 = "Jaleco"
0x11 = "Imagineer"
0x12 = "Konami"
0x16 = "Kobunsha"
0x17 = "Bottom Up"
0x18 = "Naxat | Mechanic Arms? |  Media Entertainment?"
0x19 = "Sunrise"
0x1A = "Cyberfront"
0x1B = "Megahouse"
0x1D = "Interbec"
0x1E = "NAC"
0x1F = "Emotion | Bandai Visual??"
0x20 = "Athena"
0x21 = "KID"
0x24 = "Omega Micott"
0x25 = "Upstar"
0x26 = "Kadokawa/Megas"
0x27 = "Cocktail Soft"
0x28 = "Squaresoft"
0x2B = "TomCreate"
0x2D = "Namco"
0x2F = "Gust"
0x36 = "Capcom"

Minimum Requirement

• 0x00 = "WonderSwan"
• 0x01 = "WonderSwan Color"

Cartridge ID

ID number used by developers. Maybe the same as game number for the system.

???

Totally unknown.

ROM Size

0x01 = 1Mbit?
0x02 = 4Mbit
0x03 = 8Mbit
0x04 = 16Mbit
0x05 = 24Mbit?
0x06 = 32Mbit
0x07 = 48Mbit?
0x08 = 64Mbit
0x09 = 128Mbit

Save Type

0x00 = None
0x01 = 64Kbit SRAM
0x02 = 256Kbit SRAM
0x03 = 1Mbit SRAM
0x04 = 2Mbit SRAM
0x10 = 1Kbit EEPROM
0x20 = 16Kbit EEPROM
0x50 = 8Kbit EEPROM

Extra Configuration

• Bit 0 sets vertical position.
• Bit 1 sets horizontal position.
• Bit 2 seems always set.

0x04, 0x05, and 0x06 are the possible values.

Real Time Clock

If bit 1 is set (0x02), the RTC is used.

Checksum

The sum of all ROM bytes except the checksum itself. Keep in mind that it is a little-endian value (bytes get reversed)!
