The decrypted code was extracted from a Point Blank 3 PCB, thanks to the work of Windy Fairy (and Guru running Windy's test code) This allows the game to run in MAME, although the encryption still hasn't been figured out the proper way, as it's significantly more complex than other Namco System 10 games.
The work involved from Windy Fairy and Guru of what the effort itook to be able to watch attract mode of the two games.
Cloned promoted to working -- Gunbalina (Japan, GNN1 Ver.A)
Added decrypted Point Blank 3 program code.
Both games run, but will still have MACHINE_UNEMULATED_PROTECTION until particular protection is figured out.
Somewhat reminds me of Razoola’s CPS-2 XOR files method that was used for being able to run various CPS-2 games for a few years until a solution was achieved for decryption of CPS-2 hardware back in Spring 2007.
