There's absolutely nothing out there...Lucasarts decided that TPM was to be a stand-alone product. The only patch takes care of a problem with the program launcher with DirectX 7.
That thing is kind of...well... unauthorized. We used it in-house as a test for our... unauthorized... multi-player version. (I'm getting in real trouble here with you fans, aren't I?) It's against the terms for me to distribute it publicly.
