And here's another piece probably useful info: Jp8(short = Game Cartridge) Jp3(open = Game Cartridge)

So if you can help me please do.

The lack of markings on the circuit board probably means that you have a fake FB2.

 

See this thread for details.

Yep, you have a pirate console. If you get it working, let us know.
