Problems dumping games

[jupp]

There is technically no "max" track length defined in the official .g64 specification.

but there is. at offset 0x0a in the header there is the maximum length of tracks inside the image, and that number is smaller than the longest track in these images - which is wrong. (VICE would show an error when trying to access such a track, i don't know what other emulators will do in that case)
