Description: Launch another XBE by unmounting then remounting D:

Detail:
If you want to launch another XBE (say you have a menu program) - you
have to first map the D: drive to the location of the XBE you are launching
or else it won't be able to find its media files.

You have to first unmount the D: drive, then re-mount it to the correct
device and subdirectory. Then simply call your XBE.

#else

void RunXbe (char* szDevice, char* szDir, char* szFile)
{
   //Start a standard exe here for pc version

}

#endif //_XBOX

and heres the launch.h:

CODE

#pragma once

#ifdef _XBOX

#include

#else

// Where using DirectX
#pragma comment(lib, "D3d8.lib") // DirectX 8
#pragma comment(lib, "D3dx8.lib")
#include

#endif //_XBOX

// szDevice = the device where the XBE is "Cdrom0"
// szDir = the subdirectory where your xbe is "Games\Game1"
// szFile = the name of your XBE (without the path) - "Game1.xbe"
void RunXbe (char* szDevice, char* szDir, char* szFile);

Now i call the function no problems at all and can pass my variables accross but i get a error. .xbe could not be booted.. I know its something so small.. any whizzes around?? Im not that bad a coder on xbox but this ones got me stumped..

My app is nearly finished too but i need to get this working!!

Heres how i call it:

CODE

RunXbe ("Cdrom0", "", "install.xbe"); // lets launch ourself

// szDevice = "Cdrom0" or "Harddisk0\Partition6" (where xbe is)
// szDir = the subdirectory where your xbe is "Games\Game1"
// szFile = the name of your XBE (without the path) - "Game1.xbe"

Im just trying to call another xbe for a test.. Its really the same app at the moment!

anyway, thanks for any help guys,
