User:AF/ClassExtrapolation

The purposes of this page is to list the extrapolated classes during the reconstruction phase of the 1996 Special Edition.

For the most part this is a brute-force approach. As the classes are refined/trimmed they'll be adjusted over time.

The general methodology in this case is to generate a struct with N number of contained variables (this number can be rather high at times - it doesn't account for internal sub-structs and the like mind you, but there must be a starting place).

Structure Extrapolation

Whether the structural class format is entirely correct based on what was originally present is unclear.

However in order to ease the RE process some of these subclasses have created to reasonably allow for alignment.

CGraphics

struct CGraphics
{
  HBITMAP dwGRBitmap;
  HBITMAP dwGRBitmapLoColor;
  DWORD dwGRthree;
  CPalette *dwGRPalette;
  tagRECT dwGRRect;
  void *dwGRRGB;
  void *dwGRRGBLoColor;
  BITMAPINFO *dwGRBitmapInfo;
};

CSound

This deals with both the Music and Sound.

struct __unaligned __declspec(align(2)) CSound
{
  HWND *dwSNDhWnd;
  BOOL bSNDPlaySound;
  int iSNDCurrSoundID;
  CString dwSNDSoundString;
  void *dwSNDBufferOne;
  int iSNDCurrentSound;
  void *dwSNDBufferTwo;
  BOOL bSNDWasPlaying;
  int iSNDSoundID;
  void *dwSNDBufferThree;
  void *dwSNDBufferFour;
  void *dwSNDBufferFive;
  int iSNDNextSoundID;
  DWORD dwSNDUnknownOne;
  WORD wSNDMCIDevID;
  DWORD dwSNDMCIError;
  DWORD dwSNDUnknownTwo;
  CString dwSNDMusicString;
};

CSimcityApp

Struct to address reference:

this[59]  -> 0x4C70FC - Boolean var for selecting the background or foreground palette (toggled via CMainFrame::OnActivateApp)
this[67]  -> 0x4C711C - Foreground palette
this[68]  -> 0x4C7120 - Background palette
this[69]  -> 0x4C7124 - CString One (marked as data but not with any name or reference)
this[72]  -> 0x4C7130 - CString Two
this[75]  -> 0x4C713C - CString Three
this[78]  -> 0x4C7148 - CString Four (the global has the type LPCSTR during initial detection here)
this[122] -> 0x4C71F8 - CString Array One (new alloc of 12)
this[158] -> 0x4C7288 - CString Array Two (new alloc of 12)
this[200] -> 0x4C7330 - GetTickCount() result (unmarked area - no name or reference)
this[201] -> 0x4C7334 - Program Step
