Paul Gardner-Stephen is working on an FPGA version of the Commodore 65. His goal is to make an 8-bit computer for the 21st century.
On his last update, Paul talks about his initial work adding support for sprites.
“The focus here is on implementing “normal” C64/C128/C65 sprites for existing software. As such the focus is not on adding new functionality to these sprites, in particular allowing more colours or more than 8 sprites”
You can follow his progress on the link below.
