This looks pretty sweet honestly
Pretty neat. But why an FPGA? I would imagine if you want to run software targeting really old chips, like the Z80, you might as well run it on a modern x86/ARM/RISCV processor with an emulator on Linux.
Software emulation is generally inferior to FPGAs because of inaccuracies. Also at that point you could just use your own laptop.
I’m aware that’s true for complex multi chip systems like arcade boards. The Mister project for example. But a simple Z80? I expect it to emulate virtually perfectly. Maybe not? Hence why I’m curious.
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.
