Problem opening games

[imk]

I'm having trouble with this still.

I looked in CoreParameter.cpp under the SCoreStartupParameter::AutoSetup() function.

The problem it's running into is related to File::Exists().

From there I went into FileUtil.cpp to dig around.

I made a simple modification to print the result of stat().

Code:

When you compile and first open Dolphin, it's going to pop up a bunch of dialogs as that function is called, just dismiss them all.

When I finally get to the main interface, I go to open and select the .gcz, and the result is simply "No error" (error code 0) yet the application still says the file does not exist.

The stat function returns -1, though, which indicates an error... so this really doesn't make much sense.

Code:

57:58:061 E[*]: Warning: File: D:\Games\Dolphin\Games\game.gcz
Result: -1
Error: No error
58:01:172 E[*]: Warning: The file you specified (D:\Games\Dolphin\Games\game.gcz) does not exists

Alright, since Dolphin is written in C++, I just went ahead and replaced the existing function with something more C++, and it works.

It can now find and open all games that it couldn't before for me.
