Release id #49058 : Mr. Do!
So I was trying to get the loader for this version of this game to work on my uIEC, and it would lock up every time during the load. Investigating, it looks like the initial file loads to $801, when run ($828), copies part of itself down into zero page, and the upper blocks of kernal ($f5e0 and up), then uses that to load the other parts.
What's interesting is, when I freeze it and look at $f600, I find the message "Y POLICE 1985", presumably part of the message "BROKEN BY POLICE 1985".
So, the question is, did ABC Cracking steal this release from POLICE and slap their nametag on it?
I know back in 83-85 it was a pretty common thing to slap your own name on things when you got them, before you spread them, before any formal scene rules had evolved - as I did much the same thing with some of my early Dr. Oblivion/The Trooper releases.
Anyone have any opinion on how the police message got in here? Is there a POLICE version of this crack out there?

It's from the sys-line of the first part:
1999 SYS2088 BY POLICE 1985
I'd guess Police either altered the ABC-release, or ABC used a packer made/altered by Police. |

Ahh, good eye.
Does anyone have a packer that inserts this message?

it's a modified MC-Cracken compressor, other ABC cracks uses it for example
Tour de France [french]
was packed with the same altered packer and they didn't bother to change the sysline. |

Ian, will your unpacker tool identify packer routines? |

Just curious - I've been wondering lately if there was a big list anywhere of the various packers and their fingerprints. |

The list is in the unp64.txt, for the fingerprints, there's nothing else than the sources, all unp64 does is to compare small pieces of code at different offsets. Actual syslines and texts are not taken into consideration because they are not significative, too easy to change. |
