To locate the problem, have you tried enabling the option "Use shaders"? It provides most of the time more accurate rendering.
Also, "Enable saving GE screen to Textures instead of Memory" gives better graphics when resizing the screen to a resolution larger than the PSP one (e.g. "x2" or "x3").

Does the software rendering ("Use Software Rendering") gives more accurate results? It is much slower but should also be more accurate for some rendering functions.

When I activate all three options for this particular game, the display is inaccurate and more pixelated (see first thirteen screenshots). My computer is too slow to be able to handle it (I get 6-8 FPS). If I disable "Use Software Rendering" and keep the other two options enabled (Use shaders and Enable saving GE screen to Textures instead of Memory), it is just as accurate as PPSSPP (last five screenshots). The white square box that shows up in the middle of the screen when my character is in the Coliseum is removed with these options (last screenshot shows what it looks like). However, the game runs even slower (3-4 FPS and the game takes a while to respond to what I press on the keyboard). I have also provided Logs in case you want it.

EDIT: When I enable both "Enable decoding of indexed textures (using CLUT) in shader" and "Enable dynamic shader generation", the game runs at a more decent speed (14-21 FPS).
