I noticed you can actually start at level 10, where it goes from there is anybody's guess unless someone completes level 10

Doesn't the advance 16 levels cheat work?

Besides, you couldn't stop cracking Ami stuff - if only just for the sheer challenge - even if you tried! I've got the same morbid addiction with working on HOL stuff apparently, heh!! |

If a 1988 game was virtually uncrackable, it makes you wonder why Frank Neuhaus didn't make huge money licensing his work out to other companies. Although I guess anything protected using it would automatically be A1200-incompatible (I'm guessing most Core Design games used identical schemes, hence almost all failing on anything above a 68000?)

And most Core Design games were Copylock protected. |

Just to bump this old thread, I have the PAL version of Zoom! if anyone wants it, CT RAW in the Zone! Plays fine in WinUAE so it's passed the protection check on 59.1 for starting the game

On the back of the sleeve it says '50 chaotic levels of play' so I guess there's 50.

No idea then, can't you dig into the code a bit more and see how the levels load?

Zoom 100% cracked in the zone.
Tested on a real A500 at the South West Amiga Meet |

Nice job Galahad, I cracked this one a few months ago and it had some really good protection (could have been better implemented, but still interesting to look at).
I managed to screw up something to do with interrupts that I could never fix, and lacked the motivation to make an intro for it so those 2 things combined forced it into the ever-growing "unfinished" pile on my HD :P |

Obviously the self modifying decryption wasn't great, but enough loops to put off the casual hacker, and the sneaky writing of variables to address $13c nearly caught me out when the checksums activated, having to preserve from $0 - $500 twice for when the two different decrypters were running, and the protection track read which built up a table was a nice touch as well. Memory was the massive problem, really struggled to fit the main game loader in, eventually found a tiny bit right at the end of 512k chip, couldn't touch anything in low memory as the game and intro was checking it to make sure certain variables were set correctly. Game is so-so, but the protection was a nice change |
