Ishar AGA protection fails
Easy to reproduce, you started the game from the beginning, and you just need to advance, you meet a bridge, than you advance again a bit, and the password protection appears, and there's no way to pass it, and finally the game freeze, and the only exit is the whdload quit key.
Can you help Bertrand ? Last edited by dlfrsilver; 15 March 2013 at 23:41. |

![]() for 100 miglia i can't reproduct it without play long times.... so it's interesting to have dump/reg file to look for memory location of protect code. more over fo ishar it's C+ code so it's more complicate to understand it |

@CFOU! : Interesting... I didn't know there were Amiga games coded in C++ or C. Is plain C suited for fast Amiga games using the chipset? I don't know a thing about 68K asm, but I work with C often.

in fact, under winuae, you can access the debugger too, via Shift+F12.
for what i saw, it's stuck in an ASM routine (nothing like C+ code). We will check this deeper next time you're available ![]() |

so better way to crack is to use generic research code to localised protection code which is inserted after decrunch code... i thougth have to do it.. but perhaps protection code is a bits differents after.. i will soons fix password protection check... |

the ECS version doesn't seem to have a problem. But on my AGA multilingual version, i trigger easily the password protection.
Is there any program to decompress and access the files outside the main executable ? EDIT : and in June, once you'll have more time, ishar 2 AGA will need investigation, because there is a serious bug/problem on the AGA release which actually kill the game. Even the IPF has the problem so far. |

StingRay are right, it's interpreter, for this reason manual protection request is in data files... it's more complicate, if we want not forget one protection test.... only solution to be sure all protection are removed is to finish game ![]() i am never done ishar serie (perhaps a day....) |

if problem is only in french it can be caused by long french sentence (french colonisation or civilisation cracked for this reason...) have you try in english to compare |

But I remember that the ECS pirated version I used had the maze corrupted in the fortress part (walls that could be passed like they were not there, party got stuck soon afterward). |
