This particular device can emulate multiple systems using FPGA, the one before then could only dp Z80.
My guess as to why they used an FPGA for the Z80 is that development was cheaper since they could just flash new software if there’s an error. Additionally they gained experience for this project.
With this I could imagine GPU emulation etc. happening on the FPGA maybe even bwing able to configure a sound card in software.
