What patches are required?

Guys,

Following on from my PC upgrade, I seem to remember installing all sorts of
patches over the years but have no idea what I've done with the original
downloads.

I've installed cold war crisis and resistance, does anyone know whats
needed and if its still available anywhere on the net?

I ended up on www.fileplanet.com but they want a subscription just to look
so any other hints/clues etc gratefully received.

Cheers

Torchy
