If you want to learn about FPGA development, I'd strongly recommend not starting with the Amiga core. Get a firm understanding of a much simpler core first.
The reason for this is that the Amiga core is somewhat "brittle" timing-wise, and you're likely to get occasional bad builds that simply don't work, not because you've done anything wrong, but just because that build was bad. There are random elements to how the place-and-route process works, and every change to the codebase re-rolls the dice regarding what gets placed where within the the FPGA. A well-structured project with timing constraints that match the the behaviour of the design will build successfully every time; the Amiga core, sadly, is not such a project, and its CPU core is very difficult to constrain, so learning by tinkering with this particular core is likely to be frustrating.
You might find some of my ramblings on the subject of FPGAs enlightening:
