Module Name:
|
||

|
||
|
|
Riven.cpp
|
||
|
|
|
||
|
|
Abstract:
|
||
|
|
|
||
|
|
A hack for Riven. The game gets confused about what windows version it's
|
||
|
|
running under and tries to handle it's own messages. A simple ver lie
|
||
|
|
fixes this issue, but causes the game to use a win9x only method to
|
||
|
|
eject the CD.
|
||
|
|
|
||
|
|
Fix:
|
||
|
|
|
||
|
|
We can get ddraw to correctly handle alt+tabbing by turning off the
|
||
|
|
DDSCL_NOWINDOWCHANGES flag on IDirectDraw->SetCooperativeLevel
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
This is an app specific hack, but could fix other similar issues.
