uncrackable / protected game disks
Hi,
I was wondering if there is any way to protect a disk from being copied / cracked that has not yet been broken. I remember GEOS v2.0 was very hard to crack back in the '80s but somebody managed to do it. |

There are TONS of uncracked games, but not one wants to bother with Text/Graphical adventures. I haven't seen working cracks of most of the tellarium games, or the windham hill classics games. There's no cracks of most of the early games that would get the points in the later release rules, Skyfox for instance (would make an excellent game for compo). A lot of the Accolade games too, and Datasoft. The problem is testing these games when they are quite complicated.
No working crack exists for Beyond Dark Castle iirc, it only appears to work, but you can't actually complete the game. |

CZ, I seem to remember that special version of Logo you refer to was protected by Tyger and Crisp back then. I haven't got it, I never did, Crisp might still have it though, dunno... |

Should ask him again. :)
I have a vague recollection of you and I discussing Gunship back in the 90s? :) |

So, any suggestions for the next cracking compo?
Beyond the Dark Castle and Skyfox seems like obvious candidates. It'd be quite interesting to find that "special" Logo and try that out. Or why not take any of the Interplay titles which used ProDos-emulation where you explicitly should be forbidden to maintain the original disk-structure? |

Portal was mentioned in the lemon thread, but we'd need a copy of it where no one ever played it at all, another one which alters the original if you do. :(
I'm up for a 3rd party not involved in the compo directly to pick the game to keep it fair and everyone goes in blind.
We were talking on IRC and Takedown was also mentioned, but count me out of that one... I've already looked at it before and it's a nightmare I don't want to get into. ESI is the only group to ever release it, and I suspect they either had an unprotected version or Mitch/The Dude/Eaglesoft really is the best cracker there ever was. However Antitrack might even want to get in on that one. |

**reverse cracking compo 2016**
you take an unprotected lousy game and you build all the hardest protections around it. when the game is so damnübercybersecured you take a lobotomy so you can't reveal your secrets. then you challenge the scene: "marry Jaffar or die within the hour"! uhm, no that's something else... ok: "crack my game within 2 weeks or I win the compo!"

somewhat not doable with vice around. :)
But interesting idea... often times protections had better coding that the games they protected. So that wouldn't be anything new...
Uncrackable Piccolo Mouso anyone? :D |

If you look at Exile protection or consider some hardware protections Vice can't help solve the problem if we introduce time limit. On the other hand if you consider that fact that you can hook Vice code to make memory snapshots and trace execution it makes some analysis a lot more realistic. But I agree that some protection code has been written way better than the game protected... Some others had strange imho weak points. For example original Turbo Assembler does not erase itself from memory if dongle is missing.
I wonder if we ever find unopened Portal original. Maybe someone has a clean master copy still around? |
