I dont know why chocobo uses a weird PT-replayroutine in our PSX-cracktros that make the noise over-distort. Now I can listen the music with the proper volume. 🙂

I might have some of the sources somewhere. I will take a look, I also promised M9 here to search through old backups.

Basically, the trainers are simple: An interrupt is installed which updates specific memory-locations.

As stated somewhere here by Wayne Kerr most trainers are done using Action Replay codes, so they behave like a “software-emulated” Action Replay. No Magic, no thrill.

I lost all my PSX stuff from back in the day – M9 helped me recover some GBC/Dreamcast/etc. things, but sadly the PSX directory on the backup CD was unrecoverable 🙁

From what I remember, it was a simple hook of the event handler @ $000000b0 which was patched to call your routine which just “poked” the various code/values needed…
It was Brainwalker who taught me this technique, so maybe he remembers more details 🙂

Sorry for being anal, Icarus, but it is Rob Northen, *NOT* Rob Northern.

WayneK: I think they are referring to my tool “LCF” which printed the 16bit key of a libcrypt-protected game. I wasn’t involved in Spyro but I remember that it used checksums heavily and manipulated game-flow to be unplayable. Most of the libcrypt-protected games did not include checksums which could be cracked easily, like if you take a copy-locked Amiga game without additional protection. I once read an interview with Rob Northern who clearly stated that copy-lock itself is a basic system which can be cracked easily. Only the stuff which is added around it (i.e. checksums) makes it a better… Read more »

If Spyro has never been cracked correctly, so what BabyDock is boasting about? Another ego-play…or(?).

not only that the logo looks terrible it also matches the rest of the intro in no way. Rest is fine by the way.

Apart from the logo a very nice intro. The “coppers” are cool.

“Games that implement just a standard copy protection scheme can be cracked in less than a day. Sometimes a tool is even available which does it in seconds.” … Icarus, he’s talking to you! 🙂 Funniest part of the article, 2 pages in after he describes just how much effort they went to in order to implement this super-complex protection: “I’m not exactly sure how, but I know YOTD was vulnerable because the copy protection was only run once, at boot time. I assume the crack bypassed the copy protection and then restored the data to its original state.” /facepalm.… Read more »
