I think I'm starting to understand how this works. You divide the game's resolution to get a ratio, convert to hex, search for it in cheat engine, then after finding the one corresponding to res you change the value to a widescreen ratio (as hex)? I'm probably way off though because I tried doing this with JP version of Fatal Frame 2 but nothing came up. I was searching for 3f32cccd array (and 0.6984375 float). To get that number I divided 640/447, as pcsx2 reported it..
