No, it is not Commodore 64 anymore. It won't feel like one, you can as well run an emulator. I get it, FPGA is more faithful reproduction, than pure software, but it is not a real thing, and will never be.
Last time I wanted to fiddle with a C64, I just went and flashed bmc64 (https://github.com/randyrossi/bmc64) to an SD card. Even an original Raspberry Pi 1 does a decent job of emulating it.
