Has anyone developed single chip replacements for the Special Chip 1s and 2s used in the likes of robotron, sinistar, bubbles, splat etc ?

There's too many pins to really do it cheaply.

Most of the higher density cplds/fpgas don't come with 5V IOs, so you'd have to use a smattering of smaller ones...

jrok's already coded up the vhdl to do it for his emu board, and I'm sure if there was a cost-effective way to make them he would have done so already.
