I had a DVP9000ES for many years. My ex took it :) Anyway, if I recall, it played SACD upon inserting the disk. So I agree with tonykay that it should automatically identify that its been fed SACD media. Irrespective of the remote, the unit itself has a play button on it. What happens after you insert an SACD and press play?
Sony DVP-S9000ES sacd remote function
I acquired one of these old DVD/SACD players as a hand-me-down but there's no remote. More specifically, there doesn't seem to be a way to get this to play SACDs (yes, I have quite a few of them) without a compatible remote with an SACD/CD button on it. Since all universal remotes sold these days don't have that button, and the original OEM remote is all but extinct, does anyone have a clue how to get this player to play SACDs?? I even tried buying a remote for a Sony carousel SACD player with that button but that code didn't work. I welcome any advice/leads to solve this problem.
