Yes. The site that Nick referenced has an RA-4 formula that I've used. It seems fine with fresh Fuji and Kodak paper, but it produces fogging and weak colors with some (probably old) cut-rate Konica paper I bought secondhand on eBay. (That same paper seems fine with Paterson's RA-4.) Here's another site with an RA-4 chemistry formula. I've not used this formula, though. In part I've just not gotten around to it yet, but it also requires a few chemicals that I don't have and I'm not even sure where to get them.
