it's interesting to hear your success with the Toshiba DVD drives, as I'm having no luck with mine.
(This is with Vice City btw but Securom new just the same!)
I'm using the older Toshiba SD-M1212, and I can't get a twinpeak patched CD to be recognised quickly enough.
I followed philamber's CloneCD and also Alcohol guide to make the CD, and tried a downloaded .bwa and also made my own with Blindwrite (4.4b). In all cases the CD produced when used in the Toshiba drive is really slow in authorising the disc, and when it gets into the game each time VC checks the CD again it pauses for quite a few seconds (e.g. getting in and out of cars).
The even stranger situation is, that despite philamber saying that Securom has an ATIP check, if I play with the patched CD in the Lite-On writer it authorises it straight away and plays the game fine! This is on Win XP pro with absolutely NO copying software, or DVD region fiddlers etc. installed.
Now I'm really confused as to what's going on! LOL
The only trouble is playing with the CD in the writer, is that it keeps spinning up all the time, but even the original play disc does exactly the same thing. If that little quirk could be gotten around somehow, I'd be satisfied.
Really disappointing that the Toshiba doesn't appear to like Securom (this is the first experience I've had with Securom) as all Safedisc copies work absolutely brilliantly.
