Thanks to a group effort from the guys over at AUMAP there is now the PAL dump available from the Cheap Squeak PCB. Not only that, they have converted it to a GAL20V8 device and tested it too.
This is a nice one to have as Spy Hunter is a truly great game. Thanks very much to those who sorted this out, its good that communities come together to help people out and also share these things with everyone else too.
