Very cool project! Anything surprise you about working on this? Any tips you found about implementing for FPGA?

As someone with no hardware experience, I find working with HDLs to be a very different environment and potentially hard to reason with. I did my best to document things from a software perspective (particularly for the Analogue Pocket) (https://github.com/agg23/analogue-pocket-utils/wiki). My code is also running in some capacity in most of the main core ports to the Pocket.

1800x turbo? What happens if you fast-forward a whole lot, any easter eggs?

That ends up not actually being that fast. The real goal was to be able to wake the Pocket/Tamagotchi core and have it automatically fast forward time as if the device was running that whole time. But when the FPGA fabric (and my design) limits us to 1800x, that means we get a whopping 30 minutes of sim time per every 1 second of real time. So even if you slept the device for a day, it's unreasonable to wait for it to fast forward.

Nothing special happens when fast forwarding, other than you can kill your Tamagotchi very quickly :P
