New PPU for NES PAL with FPGA

Hello World
Lot of academic article calls FPGA PPU for NES, some years Universal PPU was the first prototype of new PPU replacement for NES hardware.

Does exist today a FPGA pcb to replace NES PPU? Can remove sprite flickering with it? Is it compatible with Hi def NES HDMI? And where or how to make it?

unfished project Universal PPU. This is a PCB with FPGA to replace original PPU. The first steps are encouraging as on the video youtube but the FPGA code has some bug. The community need someone to improve the FPGA code to finish.
