Has GPL been hacked yet?

I hate to think about the responses I might get to this, but some of the times that I have seen turned with GPL on VROC lately make me start to wonder if someone has cracked this game and made some patches. Let's face it: even though Papy could have made it very difficult by burying their algorithms and using floating-point math (which has much harder values to locate), any code can be reverse-engineered if you have the time and tools to do it. Can this possibly be happening already? Or, is it a matter of discovering some loopholes in the algorithms, such as the "lowrider" setups? (Note: I'll admit that I'm not a good enough driver to keep up with the fastest, but the differences in times are getting somewhat ridiculous.) One interesting safeguard would be to have GSB check the copy of GPL.EXE by using a checksum of some sort. Unfortunately, this would also catch out those of us who have "patched" the game to change "Murasama" to "Honda", etc. Of course, just like all the copy protection schemes are eventually broken, anything can be defeated when you have access to the computer and software that is running on it. -- Doug Gordon (remove "nospam" from e-mail address)
What sort of time are you refering to?,because there are some very fast drivers in GPL,and watching there replays,they are not cheating,they are just very good. Please tell me the times you are talking about. BTW.sometimes due to warping and clock smashes online,there are some times that are to fast to be real,but this is understood.
If they're not going faster than the times found here - http://216.13.117.36/~schubi/fastlaps.htm - then they probably aren't cheating. /Christer

The time I saw was 0:57 at the Glen, which is quite a bit faster than the 1:03's on your page. Of course, maybe it was a clocksmash-generated time, but 6 seconds is a lot of time to gain. Mainly, I just noted this time as the "track record" on my Watkins Glen screen. That's what I was talking about, though. I can accept running 1:05's and 6's to the aces running 1:03's, but if someone starts running less than a minute I might as well hang it up! -- Doug Gordon (remove "nospam" from e-mail address) If they're not going faster than the times found here - http://216.13.117.36/~schubi/fastlaps.htm - then they probably aren't cheating. /Christer
I came across a guy in a VROC race last week that lapped around 1:17 at Monza. So instead of racing I watched his driving. He seemed to have warps or clock smashes at the same places on each lap saving him a couple of seconds several places on the track. It looked very much like cheating to me. Unfortunately I forgot to save the replay. -Jan Otto
What is warp? Kendall

>What is warp? In online races, when a car suddenly is somewhere else, as if it skipped some distance, it is called a warp. Remco
We are the Borg........... Set course for quadrant 8, sector 2! Warp 8! Engage! > What is warp? > Kendall
