I am emulating the iso (first emulation of ps2 in my life) of the ps2 game 'spider man web of shadows' but when i play the game, the pause menu, the starting logos they are fine but when i start gameplay or it is showing any movie, then half of the screen (the bottom part) becomes fully blank. I play the game in window mode. If somebody knows what should i do then please suggest. Thanks in advance. Please help.
