Need help changing Opera 9.5 to Opera 10

[hillsmi]

Was having trouble with TF3D Internet Browser launcher, not wanting to launch any browser.

Have that squared, now that I've flashed MightyRom.

But, the Opera browser included with MR is 9.5.

I'd like the TF3D browser launch to do Opera 10.

What do I have to change in registry for the TF3D laucher to bring up Opera 10?, or copy and paste in Windows for this to happen?

I've installed Opera 10, and it is the default, but not in the TF3D with MR (Opera 10 only comes up as the default if I choose it from Programs).

Thanks in advance.
