+Gameboy ROM Header Info :: SephirothBCH :: v1.01 :: 2000/11/28

+\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
+\\\ After the release of this document, I am temporarily \\\
+\\\ leaving the coding and emulation scene. The last few \\\
+\\\ weeks of my life have been especially rough, mainly \\\
+\\\ brought on by the death of my uncle, Roy Colbert. \\\
+\\\ I would like to dedicate this doc, as well as any \\\
+\\\ other progs I make to his memory. \\\

+
+History:
+_______________
+v1.01 - Added some new licensees, fixed some
+ descriptions.
+v1.00 - Initial release.
+_______________
+
+This information was taken and compiled from Martin Korth's
+NO$GMB emulator. Best viewed in DOS EDIT.
+
+Every Gameboy ROM header starts off at the HEX offset 0134.
+
+Title/Name of ROM
+=================
+The title of a ROM is 15 or 16 bytes long. It seems that if the extension
+of the ROM is GBC, the 16th byte denotes CGB features. This is then confirmed
+by reading a HEX value of 80 from that 16th byte. I'm not sure of this yet,
+but it seems correct. Any title bytes that are unused are filled with NULLs.
+
+New licensee
+============
+This is two bytes long. These are two HEX values put together to make a
+quasi-number value. For example 30h and 31h translate into 01. 31h and 32h
+become 12, and so on. There are some companies also present in the licensee
+section, later in this document. Known combos are as follows, in the trans-
+lated form above.
+00- none 01- nintendo 08- capcom
+13- electronic arts 18- hudsonsoft 19- b-ai
+20- kss 22- pow 24- pcm complete
+25- san-x 28- kemco japan 29- seta

+92- video system 93- ocean/acclaim 95- varie
+96- yonezawa/s'pal 97- kaneko 99- pack in soft
+
+SGB features
+============
+Only one byte long. A HEX value of 03 says that the cartridge has added
+features for Super Gameboy. Any other value, especially HEX 00 denotes
+a non-SGB cart.
+
+Cartridge type
+==============
+One byte long. This is one of the bigger values in the cart. This byte
+indicates which memory mapper the cartridge uses, whether it has Rumble
+features, RAM, or battery features. Valid values are as follows (in HEX):
+00- ROM 01- MBC1 02- MBC1+RAM
+03- MBC1+RAM+BATTERY 05- MBC2 06- MBC2+BATTERY
+08- ROM+RAM 09- ROM+RAM+BATTERY 0B- MMM01
+0C- MMM01+RAM 0D- MMM01+RAM+BATTERY 0F- MBC3+TIMER+BATTERY
+10- MBC3+TIMER+RAM+BATTERY 11- MBC3 12- MBC3+RAM
+13- MBC3+RAM+BATTERY 15- MBC4 16- MBC4+RAM
+17- MBC4+RAM+BATTERY 19- MBC5 1A- MBC5+RAM
+1B- MBC5+RAM+BATTERY 1C- MBC5+RUMBLE 1D- MBC5+RUMBLE+RAM
+1E- MBC5+RUMBLE+RAM+BATTERY FC- POCKET CAMERA FD- Bandai TAMA5
+FE- HuC3 FF- HuC1+RAM+BATTERY
+*** The Bandai TAMA5 mapper was designed specifically for Tamagotchi. ***
+
+ROM size
+========
+One byte long, fairly simple. ROM sizes range from 32K to 4MB. Valid HEX
+values are as follows:
+00- 32k 01- 64k 02- 128k 03- 256k 04- 512k
+05- 1024k 06- 2048k 07- 4096k
+
+Save RAM size
+=============
+One byte also, self-explanitory. Sizes range from no RAM, to 32K. The most
+common ones used are 8k and 32k. HEX values:
+00- 0k 01- 2k 02- 8k 03- 32k
+
+Country code
+============
+Once again, this is only one byte long. Valid HEX values are 00- Japan and
+01- Non-Japan.
+
+Licensee
+========
+One byte long, this makes up the bulk of the entire document. Some of the
+names are truncated (*), because they are too long for NO$GMB to display.
+Anyone who has the full names of the truncated licensees please email me, and
+you will get credit for them. Here are all of the valid HEX values I found:
+00- none 01- nintendo 08- capcom
+09- hot-b 0A- jaleco 0B- coconuts
+0C- elite systems 13- electronic arts 18- hudsonsoft
+19- itc entertainment 1A- yanoman 1D- clary

+Header Check
+============
+One byte long. Not sure how this value is attained or checked. Email me if
+you know, you'll get credit.
+
+Global Check
+============
+Two bytes long. Perhaps this is a checksum of the entire rom. It might not,
+since it is only a 16-bit value. Email me if you know.
+
+-----------------------------------------------------------------------------
+
+And so ends this document. If you have anything to add, or know of an error,
+email me at SephirothBCH@theglobe.com. The next version of this document will
+have explanations of the global and header check, and information on mappers
+such as MBC1 and MBC2. Thanks for reading!
