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

Nice one Burgie, too bad I am burned out on C64. Then again they can lick my user port because I've already raped their silly protection and even released a tool for it ;)
For those who chose not to use it, I commend you. You'll have some fun reverse engineering and prove you are a real cracker and not some wanna-be.
As a veteran of EA games, I'll say that there may indeed be protection buried in the game, so you should test thoroughly before you release.
Good luck and have fun all ye who dare to enter, and I await to see who takes up this challenge and releases some nice work. |

@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? |
