=GameBoy Developer Cartridge Variants=
There are various different kinds of Gameboy prototype or development cartridge.

This page was written for the intent of ensuring that the variants are documented as best as possible.

Many of the images below are sourced from varying seller listings at Yahoo Auctions, Mercari, or Ebay.

notice: As Gameboy prototype and developer cartridges are over 20 years old, the information about them is obscure and difficult to ascertain. This info below may not be the same for all variants of the boards.

EP-ROM: DMGC-MBC1-2M-01 and DMGC-MBC2-2M-02 1989

prototype white label: DMG-B02-01 1998

Standard white Label: DMG-B02-12 1998

Rumble G/A-S: DMG-B03-11 1999

Blue G/A-I: DMG-B04-02 2000

==EP-ROM Board 01:==
The EP-ROM variant of the Gameboy flash Cartridge Board typically has a large protruding EP-ROM chip at the top, exposing the internals of the board in a fashion that will become common in the other forms of the Gameboy Developer cartridge. In many cartridges the Flash of the EEP-ROM chip is exposed, which can be very dangerous for the data that may be contained. 

The EP-ROM might have various model numbers, many are very faded.

There may be a copyright of 1988 from AMD.

It appears there is no standard front label.

Below the EEP-ROM is an ID code indicating either DMGC-MBC1-2M-EPROM-01.

The year on the back of the board indicates 1989 at the top right.

The MBC1 chip appears to be a DMG MBC1B Nintendo S91263A chip or a MBC1B1 Nintendo S9311 1A

possible EP-ROM ID codes are: AM27C010-205DC 12.5V PGM 934DYV3 with an unknown manufacturer. 

Another example might be D27C10010-20 8747EX002 made by NEC, or D27512-200V05 U742238MS OO 1 '85.

the R1 is next to the dip switches.

Both seem to contain a CR1616 battery as well.

==Other Form Factors:==
There may be additional form factors for Gameboy developer cartridges, or custom versions.

Examples of these are the very tall Gameboy dev carts, or the custom variants used by Gametek, and possibly a megaman 4 cartridge from Capcom in which the EP-ROM might say TOSHIBA TC57400AD-120 JAPAN 9305EAK VPP12.5Y.

A board custom made by Gametek or by someone contracted in Korea was able to make an EP-ROM and presumably a board with 8 dip switches. 

The board has 4 SRAM chips, all untitled.

The boards ID code is SPIDR100.

This board has silver pins at the bottom and the back has a black shroud over it with a sticker saying "108"
