Re: Help with ADFS E+/F+/G

I've noticed that the fragment table is split into the same number of zones as the disc (4), and each zone starts at sector offsets (C6800,C6C00,C7000 and C7400), but I found taking the offsets from the beginning (C6840) and then subtracting 3E8 until the offset is less than 3E8 makes the calculati...

Help with ADFS E+/F+/G

Trying to figure out the ADFS F format. I've managed to get S,M,L,D and E OK (negotiating the fragment maze!!), but the F eludes me. I have worked out a way around the offsets of the fragments. I've noticed that the fragment table is split into the same number of zones as the disc (4), and each zone...

Superior still sell their games, if they have them stock, that is. Steve Hanson, Richard's brother, still runs Superior Software (while Richard runs Superior Interactive). Can't remember Steve's email address, but if you ask Richard, he'll let you know - richard@superiorinteractive.com

Re: A310 - late production or relabelled A4x0/1?

I had a 310, which I fitted a hard drive to, and ARM3 and 4MB RAM. I then cut a hole out of the label for the hard drive light (the hole for the LED was already in the facia). I then got hold of, somewhere, a A440/1 and swapped over the labels. The 440/1, IIRC, was not as highly specced as the 310 b...

Re: Repton - Around the World in 40 Screens - 80 Track Version

The 80T and 40T are identical, as far as I am aware. Certainly no extra levels. The disc itself, IIRC, is copy protected and is likely just going to be data saved directly to the disc (i.e. no filename). Without digging out my ATWIFS floppy, and rigging my Master up again, I can't be certain.
