Some memories rewritten few days ago.

I'm thinking of implementing other C64 chips in a FPGA :D

That is just such a waste of time and energy.

I love it!

Say, what is the program/cartridge in the upper right-hand corner?

Also, how much of the FPGA are you using? Are you planning on putting the VIC-II on-board with the CPU in the same chip?

It's a enhanced basic with some extra features like fast tape loading. It was very popular in Poland years ago.

314 slices in Xilinx FPGA, 621 logic elements in Altera FPGA and approximately 2,5k gates (using BuildGate).

Yes, video and other peripheral devices.

Did you design your own CPU core or use an existing one? VHDL or Verilog?

That's my own design in VHDL.
