I've tried to have a go at extracting the machine code from the magazine listing Wizard's Castle (here) - I've had an interest in this game (see this post) for a while.

I decided to have a go at extracting the machine code hidden in the DATA statements, and then attempt to *SAVE the generated code from 6C00 to 7800 (I believe it contains sprite data, as well as assembly language for rendering and collision detection among other things)

The disc image below contains what I believe to be the generated file (called WIZ). On the Mac however, I've attempted to use Disc Image Manager to extract this file, but (unless it's a Mac OS thing), it seems to contain nothing?

The WIZ file contains something as I've performed a *DUMP within the b2 emulator with this disc image, and there's definitely something going on in there.

Can anyone have a go at this disc image, and see if I'm going in the right direction? I ultimately want to fling this code into https://www.white-flame.com/wfdis/ and hope it resembles something I can learn from.

It's a cute looking game, with an unforgiving level of difficulty, would be great to see this disassembled :)
