In games in which don't have inis or consoles, how do I find / calculate the default FOV? I'm trying to using memory hacking to fix some ps2 games within an emulator.

There's no easy way. Every game is different.

The easiest way to figure out the field-of-view is to modify the field-of-view via in-game actions and check for changes.

Stand still, search in memory for an unknown value, zoom in, search in memory for a decreased value, zoom out, search in memory for an increased value, and then here I like to stand still and search for values that haven't changed. It will filter out a lot of items. I repeat this search until I feel like enough have been filtered out that I can continue with searching for increased or decreased values.

The field-of-view could be in degrees or radians. It could be a horizontal or vertical field-of-view. It could be a float or an integer (it's usually a float, but I've seen on occasion where it's an int).

How would you go about finding it if there were no way to change the FOV normally? (Like a Zoom Function)
