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.

== 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 presumeably a board with 8 dip switches.
