Gunbird - Psikyo 1994 (repair log)

The game was stuck in a reset loop.
After a quick inspection of the board I found the only Fujitsu chip installed is used to generate the /RESET signal.
It was obviously bad (it's a MB3771)...
I tricked it by shorting two legs and game booted fine:

Very easy this time. Everything happens!
