Well if you can manage to get raiden iv to rotate without crashing then you are one step ahead of me. You'll have to explain how far you've gotten and I can help.
Ok..I will try to explain it but i haven't done anything special or too difficult.
1) First of all I execute DXWND to run RAIDEN 4 Windowed
2) Then I rotate screen (I use Irotate)
3) Then I open a .bat that executes Raiden 4 then waits three seconds and the finishes..when the .bat window disapears automatically the Raiden 4 window appears..
In orden to resize, relocate and delete borders and title of Raiden 4 window I use the program "actual window manager", I use another program to hide the windos taskbar...and I open a black image ..as result what I see..is the same that you did with the wrapper for Raiden III..
All of this runs automatically...in order to get it I use a Macro recording program JITBIT MACRO RECORDER..this program allow you to record your macro, optimize it and the create and exe archive that executes that macro.
To close Raiden 4 and get everything to the normal state in my computer I use another Macro..that executes when I press ESC Key (I use another Macro Program that works with Hotkeys (Hot Keyboar pro)..
This Macro Closes all the programs and rotate the Screen to the normal position.
Problems: The Macro to Start takes about 8 seconds your wrapper 1 second..to exit the other macro needs 2 seconds yor wrapper...0 seconds haha
PD: I though that your Raiden 4 wrapper problem coud be that Raiden 4 ir order to run needs that the window that calls the game finishes after the game is called but before the game is launched...that's what I managed to do by waiting 3 second and then closing the .bat that launches the game. Maybe in yor wrapper you can call to a .bat file that makes the same that mine instead of launching the game directly...it could work...I would try myself but I don't know how to use Autohotkey very well...
If I did'nt explain something correctly please ask me..i know that my english could be better
