I seen that, it appears to be slow progress. It would be nice to have different levels of expansion for the CD32 and not just an accelerator. Some people would like a low end memory expansion board, not everyone would go for an expensive high end accelerator so options need to be available.
The reason i wanted to do an expansion board was for the RGB output and i didn't want to solder wires to the board, and at the same time allow simple upgrades for people.
There are probably lots of options for newer FPGA accelerators but alas, over my head. WHDload compatibility for all games i think is the goal, anything else is just gravy
