@JorjVirus69

Your wrapper need a more proper login. Some games may not login because events are not send in correct order, take a look in XBOX360 SDK help file. xlive is not documented at all on Windows platform, but XBOX360 have same API! Also XOVERLAPPED structure handling is a problem (Asynchronous IO). NOTE: LocalAlloc can cause some troubles, better use HeapAlloc.
I also attached my old modified xliveless source, it may help because I found many functions prototypes by reversing original xlive.dll and by use of XBOX 360 SDK.

Hym, seems that login is crashing Bioshock 2... It crashes after sixth XUserGetSigninState call.

EDIT: Bioshock 2 need a proper implemented XUserReadProfileSettingsByXuid, also it calls xlive export #5372 (which purpose is unknown for me).

Read my edit. Creating emulator for one game is much easier. Creating emulator for all games is complicated task, because it must behave exactly as real XLive, and Xlive emulation is hard - it use event system (sign-in is event based) and asynchronous I/O.

PS: XUserReadProfileSettingsByXuid prototype should look like this, included needed structures:

Code: Select all | Line number On/Off | Expand/Contract
  1.  
  2. typedef struct _XOVERLAPPED             XOVERLAPPED, *PXOVERLAPPED;
  3.  
  4. typedef
  5.     VOID
  6.     (WINAPI *PXOVERLAPPED_COMPLETION_ROUTINE)(
  7.     __in    DWORD                       dwErrorCode,
  8.     __in    DWORD                       dwNumberOfBytesTransfered,
  9.     __inout PXOVERLAPPED                pOverlapped
  10.     );
  11.  
  12. typedef struct _XOVERLAPPED {
  13.     ULONG_PTR                           InternalLow;
  14.     ULONG_PTR                           InternalHigh;
  15.     ULONG_PTR                           InternalContext;
  16.     HANDLE                              hEvent;
  17.     PXOVERLAPPED_COMPLETION_ROUTINE     pCompletionRoutine;
  18.     DWORD_PTR                           dwCompletionContext;
  19.     DWORD                               dwExtendedError;
  20. } XOVERLAPPED, *PXOVERLAPPED;
  21.  
  22. typedef enum _XUSER_PROFILE_SOURCE
  23. {
  24.     XSOURCE_NO_VALUE = 0,
  25.     XSOURCE_DEFAULT,
  26.     XSOURCE_TITLE,

  38.             LPWSTR pwszData;
  39.         }string;
  40.         float fData;
  41.         struct {

  43.             PBYTE pbData;
  44.         }binary;
  45.         FILETIME ftData;
  46.     };
  47. } XUSER_DATA, *PXUSER_DATA;
  48.  
  49.  
  50. typedef struct _XUSER_PROFILE_SETTING {
  51.     XUSER_PROFILE_SOURCE source;
  52.     union {
  53.         DWORD dwUserIndex;
  54.         XUID xuid;
  55.     }user;
  56.     DWORD dwSettingId;
  57.     XUSER_DATA data;
  58. } XUSER_PROFILE_SETTING, *PXUSER_PROFILE_SETTING;
  59.  
  60. typedef struct _XUSER_READ_PROFILE_SETTING_RESULT {
  61.     DWORD dwSettingsLen;
  62.     XUSER_PROFILE_SETTING *pSettings;
  63. } XUSER_READ_PROFILE_SETTING_RESULT, *PXUSER_READ_PROFILE_SETTING_RESULT;
  64.  
  65. DWORD WINAPI XUserReadProfileSettingsByXuid(
  66.     DWORD dwTitleId,
  67.     DWORD dwUserIndexRequester,
  68.     DWORD dwNumFor,
  69.     const XUID *pxuidFor,
  70.     DWORD dwNumSettingIds,

JorjVirus69, I want to personally thank you for this solution you created. You saved me weeks of frustration caused by the inability of GFWL to save my game progress in BAC GOTY on Windows 8. That's the only game I have had trouble with trying to find a workaround, and it was so simple. Thanks man, you're awesome. Side note: How far along are you with the development of XLive's next update? No rush, just thought I'd ask.

No, the project is not dead and it will not die as i need it myself too.
v2 is in the works, about 30 % complete, however that means i will not make any fixes or patches until it is complete.
Also, this is not my primary project at the moment, so it will take some time until you hear more of this.

@JorjVirus69

You can use my modified xliveless source for function like XShowKeyboardUI (required by F1 2011 for user name and save bolid setting), and XNotifyGetNext (events are needed for some games to proper login).
Attached my current work (Bioshock 2 works now, but DLC is not supported yet).

PS: Can you tell me some spec about XEnumerete? Because structure returned by this function seems to be different than on XBOX360.
PS2: You created fake HANDLE values like 0xDEADCODE, but this will throw exception when game call XCloseHandle/CloseHande on such handle. I'm overcome this by creating fake, not used mutex, it can be safe closed by CloseHandle.
PS3: Bioshock 2 with yours emulator crash at XEnumerete, it is a null pointer somewhere in it.

Already implemented properly in v2, XShow actually work as intended: they display an overlay.

Can you be a little more specific ?

At first i didn't need handles, and some code from those times has survived. v2 has a dedicated handle table now.

Probably due to a previous call to #5372 (XMarketplaceCreateOfferEnumerator) as you pointed out earlier.


PS: I can't open your archive (using 7-zip here).

#5356 is a dlc related function:
Code: Select all | Line number On/Off | Expand/Contract
  1.  
  2. HRESULT WINAPI XContent_5356( DWORD MustBeZero, XCONTENT_DATA *XContentData, WCHAR *Buffer, DWORD *Length)
  3.  

This function and #5357 are the cause of many dlc related crashes as they are unimplemented.

Also XCONTENT_DATA is not the same from 360, it's something like this:
Code: Select all | Line number On/Off | Expand/Contract
  1.  
  2. typedef struct _XCONTENT_DATA
  3. {
  4.     DWORD   Unknown1;       // (1)
  5.     DWORD   Unknown2;       // != NULL
  6.     DWORD   Unknown3;       // Content type ? (2)
  7.     BYTE    ContentId[20];
  8. } XCONTENT_DATA;
  9.
