Onimusha 3 for PC

[Nightmare]

Hi,
I have another problem. It has nothing to do with the thread. But I didn't want to start a new thread about this game

I've got the DVD-Version (EU) of this game.
And it is protected by secuROM!!
No idea which version.
GCW writes that the game hasn't a protection.
I think they mean the CD-Version.
My question:
Is it possible to use the EXE-file of the CD-Version???
If yes, can someone send this file here??
And there is also a patch for this game (see Sweetsensation's post)
So maybe it is possible, that I use a patched EXE-file of the CD-Version.
Thanks for help

P.S. My friend has big FPS problems. He has a Pentium 4 3,4 GHZ, 1 GB DDR2-RAM and a GeForce 6600 GT.
Maybe the patch will fix it, we will try it.

And sorry for my English
