Asura Blade (Fuuki 1999)

This dump is taken from a ROM board with number FG-3J ROM-J
There's nothing on the board except some 4M EPROMs and several
surface mounted MASK ROMs.

The connectors on the board and the size of the board is similar
to Jaleco Megasys32, however it's not compatible with it due to the
connector spacing being different. The physical size of the board
is too large to fit an SSV board.
So, I have no idea what the main hardware is, the game probably
runs on a custom Fuuki system board named 'FG-3'?
