Whilst PSSE doesn't seem to have a way to make backwards-compatible sav files, backwards compatible raw files can still be made. This can be done through the API as mentioned, or, to do this in python the writerawversion function will get you there. For example, when using PSSE 35, to save your case as a PSSE 34 compatible raw file you could use the following command.

psspy.writerawversion(vernum = '34', out = 0, ofile = 'Filename.raw')
