I'm hoping someone implements a full TG-16/TG-CD via FPGA with HDMI out. That is how PCE/TG-16 will continue to live on outside of crappy emulators. PCE/TG-16 deserves to be properly preserved and FPGA is the best way to go.
They did. It’s called UPPERGRAFX/UPEEGRAFX...
No, he means the entire system emulated on an FPGA, not anything that attaches to the rear of the PCE, as the UperGrafx does.
Incidentally, a guy named Ki has had a working FPGA implementation of the PCE for about 10 years now; he has just started taking another look at his project again. Hopefully that will bear fruit sooner than later.
