It sounds like you're using the actual Tracing Layer feature, rather then an image imported to a layer. I just tried it, and it's pretty easy. It only took like five minutes, and that's including the time it took for me to figure out which code lines I'd need to change out, so it shouldn't take more then a few minutes.
First you'll want to comment out, or delete, the code block that loads in the Tracing image. So look for the following line:
Code:
Wait: 0.000s EvType: Command CommandID: LoadTraceImage Tracing Image: {
That line will be followed by binary code (likely, a whole lot of it), which makes up the picture you used for the tracing. You'll want to comment everything out, or delete, the code starting with the line of code I posted above, to after the following line:
Code:
} // End of tracing image binary data.
With that done, you've removed the tracing image, but to be sure that the program isn't going to try and call any unwanted/unneeded lines, you should also comment out the following lines:
Code:
Wait: 0.819s //EvType: Command CommandID: CID_SetTraceVisibility ParamType: flag Value: { true }
and...
Code:
Wait: 0.549s //EvType: Command CommandID: CID_SetTraceVisibility ParamType: flag Value: { false }
After that, you should be done.
