Is there a place I can find nes_ppu.vhd from pace v1? The target matrix says that the NES works in v1 but I am unsure of how to find it.

Thanks,
Kevin

There is no nes_ppu in v1.

v1 was an implementation using the standard pace architecture - bitmap, tilemap and sprite engines. The main NES logic is contained within the platform.vhd file. There's just enough functionality for SMB and WRECKING CREW, and that's about it IIRC.

It was purely a proof-of-concept design, and to learn more about the NES.

There's a chance it won't compile atm. In any case, I haven't done a DE1 implementation - not sure if it actually fits, it has been a *long* time since I played with the NES, and even longer since I played with v1.
