Interesting ! ROMs are basically a programmable logic devices, the only difference is that they're purely combinational and have only fixed input and output pins (they can't be bidirectional and outputs have a common enable signal). So basically it'd be the same as doing it with PAL chips except it's even more limited.

Since it's the bottleneck of available chips on the market, you should start by making a valable "PPU" with only EPROMs (and maybe a DAC for the composite video signal !), and that'd already be impressive. If a "real" CPU and sound chips are still needed it's still impressive.

Hahahah, naiss. That's something I have wanted to do with my EPROM stash for years but never got around to...
