Ok, heres the results of testing Nascar 2003 V 22.214.171.124. using the Twin Peak method (thanks to Philamber for pointing me to his guide, very well written BTW).
Ok, i used CCD 126.96.36.199 to make an image, using default settings. Then made a BWA file using 4.2.5. Blindwrite.
Then used Twinpeak to patch the image with the BWA file.
Then burnt to CDRW at max speed.
Result - CDRW just sat an spun in my Liteon CDRW, would not even recognise the game, let alone try to start it.
To check, i put my back up in that i know works, the one i previously had made with Blindwrite 4.2.5. Now that didn't work either. Was recognised but wouldn't start game.
Thought what the heck is going on here.
Then remembered something i discovered a long time ago, and on a hunch uninstalled CCD 188.8.131.52 (which i previously did not have on my system).
My Blindwrite copy now runs fine again.
The Twin Peak copy is now recognised, but, wont start the game. The securom spinning disc image pops up for a second, then closes back to desktop.
Now this is the first time i've tried using Twin Peak method, as i seem to be one of the lucky ones with Blindwrite 4.2.5, as it has copied everything i've tried on it, including SD 2.9, only thing it hasn't done is StarForce 3, which i understand simply cant be done at all (yet!).
I think i followed Philambers instructions correctly, so therefore i would conclude by saying that the Twin Peak method didn't work in this instance.
Further CCD seems to be blacklisted (once again), as with it installed, my Blindwrite 4.2.5 copy would not run either, only when i uninstalled CCD did that work again (I didn't install virtual drive either, and did not have CCD Tray running when i tried to start the game).
So there you go, over to the experts for more discussion...
