New working machine

Wild Fang (set 1) [Tailsnic Retroworks]

I do find the updated year (2 years newer) on the title screen a little suspicious, as mentioned in private.

While the set is very different to any currently supported set, came from an original PCB and is clearly a previously undumped revision, a leap of 2 years in the copyright date could indicate the string has been hacked.

2 years was a long time in the industry back then and it's uncommon to see dates updated like this.
