Somebody please have a heart???...Please??
 

I know there are so many people having problems and I am one to add to the list.
Just when I thought I had the problem solved, BAM..I can't copy again! I tried every program that big papa recd and the ONLY
thing that worked (notice the ed on the end)
is PSX v5.0! I have an old 2x sony burner and
have succesfully copied DOA2, MDK2, NFL2k1,
Virtua Tennis. I have UNSUCCESSFULLY copied
Tony Hawk2, Soul Caliber, Test Drive la mans,
Tokyo Extreme Racer 2! I did not change any
parameters on the program. What happened?
These are all self boot games. Just when I
thought I was getting somewhere:( Please
help.

The problem may not be with your burner. One of my burners is a trusty old Memorex CD-RW2216. This has the best read capabilities of any burners yet, (well compared to my Plasmon and Plexwriter). Usually if a game doesn't copy in the newer drives it ALWAYS does in the Memorex. But I've come across a couple of weird things when making another copy of JetSetRadio and MetropolisStreetRacer. I usually always use the latest version of DiscJuggler to do my burning and it's with this that I burnt the aforementioned games. Now this next bit may be a bit tricky to understand, so bear with me... The original copy (borrowed from a friend) copied fine, (this copy of the original copy will now be referred to as mine). Now when I burnt my copy, the new copy didn't work. A few CD later...still didn't work. then I switched to WinOnCD and copied my copy with that program and it worked!
So basically, try a different program from your normal one, don't know why this worked, but hey!
