Here the FFX save, the first slot should be the thunder plains, second the very beginning of Guadosalam.
Try this, copy from my save files "data0000.bin" and "data0001.bin" and paste them in your save PCSE00293\SLOT0\(overwrite your files). I think that in order this to work you need sce_sys folder from your save, this probably is the conflict and reason for error E-80800034. But I'm guessing here.
Here is my Uncharted - Golden abyss save (EU) all chapters completed, can be used on pstv (chapter 12 is unplayable, but can be skipped).
