Nebulous Bee, like Gallag, was a bootleg copy of the very popular Namco Galaga game released in 1982. While the genuine Galaga board is populated by many custom ICs, both Nebulous Bee and Gallag implement this via discrete logic and CPU based circuitry while at the same time maintaining full hardware-software compatibility. In the end, the discrete hardware has proven itself to be far more reliable than the Namco original.

Nebulous Bee also simplifies the pinout. Unlike Gallag which uses a 44 pin edge connector and a 5 pin 2.54mm header for video, Nebulous Bee jams everything into a single 36 pin edge connector.

As a result, neither of these games are pinout compatible.

For the original Galaga adapter see the Namco Galaga to JAMMA Adapter page here. For the Gallag adapter see the Gallag to JAMMA Adapter page here.

Game Compatibility

Only the Nebulous Bee bootleg board can be used with this adapter:

The adapter has been tested with a Nebulous Bee board.

Note: There are other Gallaga bootleg boards out there that not compatible with this pinout. Besides the common Gallag boards, there are many other variants as well. One such example is the an obscure Galaga clone with yet another 36 pin pinout which resembles a Falcon pinout.
