Please excuse me if I'm remarkably pleased with myself today!
It's a personal grail of mine too, although I never really expected to ever get within a 1000 miles of having an actual cassette, and now that it's dumped I'm hoping to use the data to repair or substitute the tape and get an actual Angler Dangler machine together.
I'm hoping to be able to convert a Burgertime security dongle but if anyone happens to have a spare Fishing or Angler Dangler dongle they want to sell, please PM me. I'm also looking for a maquee or at least a decent pic of one.
BTW I noticed how buggy Fishing is, it easily gets confused and loses your place on the playfield when you cast very far out and often messes up the time remaining, I'm anxious to see how much improvement is in the new version. I also noticed that if you manage to reel in your line all the way without catching a fish (tough to do) it'll continue down past the fisherman, over the shore and completely crash the game when it goes off the bottom of the screen!
That would have been a fun trick to piss off arcade operators, especially given how long it takes to reboot DECO machines!
