Event id #2314 : C64 Cracking Competition 2015
Howdy Crackers!
These days the cracking scene is pretty active, but it seems most effort is spent on rushing out a version first with non-protected games.
Now that we found this nice original that hasn't been cracked, we thought, let's turn it around. Have a cracking competition with all of you with a full price EA game, including a nice protection. So here we go with the first C64 Cracking Competition 2015!
You are invited to crack "Return of Heracles" (C) 1983-1986 Electronic Arts.
Download the original here: http://sh.scs-trc.net/return_of_heracles.d64
Please read the rules carefully, and take all the time you need, quality over speed please :)
Rules:
- Submit your entry before or at 23:59 saturdayevening the 28th of March 2015 by email to c64crackingcompetition@hushmail.com
- Your release must fully run on a stock c64 + 1541.
- Your release must be filecopieable and packed.
- Your release must contain a crack intro, but you also must provide an introless version. This will be used to accurately measure size.
- Recracking is strictly forbidden, you must crack the original we provide. When in doubt, we will dig through your release and ask a few questions to confirm you really cracked it yourself.
- Individuals may only be part of a single release, so a group may enter multiple cracks, provided they are done by other members.
- You are allowed to use whatever tools you want.
Calculating Results:
50% of the result will be determined by public voting, either using or own voting system or on csdb. Stay tuned for additional info.
The other 50% of the result is calculated by the compo organizers using the following criteria:
- The shorter the better *)
- The faster it loads the better
- Proper saving capabilities
- Full PAL/NTSC compatibility
- Amount of bugfixes (if any bugs present in game)
- Amount of trainers (no double trainers)
- Minus points if you introduce bugs and need multiple versions
- The more devices besides 1541 (or compatible) you support, the better
- Optional REU support is also nice
*) We explicitly do not want to discourage the use of large intros, hence
the introless version requirement.
Most of all, have fun cracking this full price game!
The Organizers,
Peacemaker/Hitmen

@Bacchus: google can find the .g64 file.
@Peacemaker: well, the quality-software version of the game was cracked by antiprotect, so if ECA just rebranded it with no big changes I don't think it can be a 1stie... or perhaps I'm wrong?! |

EA Pirateslayer has a key-track which is not emulated by a .d64, so one could assume it is patched ( haven't seen a Pirateslayer without that key.. yet :) ).
There are a lots of Pirateslayer protected EA games. Marble Madness seems to be one.

First time I see such a messed up way of loading a file. |

ZeSmasher: quality-software version? You mean the 3 years older version? Has huge difference to the one here. Ofcourse there are changes. Jusr compare the intro (f1) and you ll see =) |

Ok, so the actual protection is gone. Thanks for the link to the G64 but then again I don't plan to do more work than needed ;-)
Gosh I'm rusty.
The "loader" loads to FFFA and I guess it then also loads over the loading pointers that the Kernel routine uses and can fork the loading to a totally diffeent place.
Tools used so far:
* VICE (with my Action Replay in it)
* DirMaster 3.0 (the disassembler doesn't support illegal opcodes)
* Regenerator 1.3 (which cannot handle files that wrap at FFFF) |

done some more investigation myself as well, and I can confirm that the actual copy protection has been disabled in the .d64. 3 bytes got patched in drivemem.
it doesn't save much (any?) time though, everything else of the protection is still there. |

Hi,
it is clear that this can not be the original disk as it is D64 - so it can not have any copy protection :) Can someone link here the original file - I mean the G64 original disk? |

weird, I just copied that g64 to d64 and result is identical to the d64 we provided in the first place. so either the g64 is just a copy of the d64, or there is no real copy prot ;) |
