https://rm-rfroot.net/nes_fpga/ Implemented the original 8-bit Nintendo Entertainment System within an FPGA (currently Xilinx, but soon to be ported to the Altera DE2-70). The design is the complete original MOS 6502 + the nintendo picture processing unit, audio core, VGA controller, GUI interface using Qt, etc, etc. It's far from done but it could give your future students another project idea to try out for themselves.
