If you want to easily change your TEN sounds to Tr1 / TR2 or TR5 then download this.
To override the sounds you will need to :
Open your project in Tomb Editor, open the level settings and goto the "Sound Infos" page.
Next, load the TRx_Override.xml cataloge and drag it to the top of your stack as shown here.
Next, go to the "Sound Samples" page and add a new folder and point it to the Override samples folder you want. For this example I am using TR1.
Happy "snuh-ing"
Enjoy!
