Re: Disassembling large programs

I tried a lot of the available Atari disassemblers and was satisfied with none! Hence the way I deal with disassembling Atari stuff is as follows: I convert the binary to a standard Amiga executable (I have coded my very own tool for that which handles debug symbols and other stuff) and then simply ...

Re: KICK OFF 2 + WORLD CUP 90

I have finished the decrypter for the Atari version of Kick Off 2, encryption is similar to the Amiga version, only in the final decryption loop different add.w/sub.w instructions are used for calculating the keys (Atari: sub, Amiga: add) which isn't too surprising as also for different Amiga titles...

Re: KICK OFF 2 + WORLD CUP 90

The Amiga protection is Anco's COBRA X-ROM. Same for the Atari version, yes I have just checked the code of the Atari version! And I also have, just for fun, started to code a decrypter for the Atari version too as I want to see how different the encryption is compared to the Amiga version.

Re: KICK OFF 2 + WORLD CUP 90

"i know he protected Kick Off (Amiga and ST) and Kick Off 3 (Amiga only). Maybe someone at Anco reworked his protection, it "could be" possible" That's just one of your replies which can be found in this very thread. And it's interesting how you now claim that the protectiions is...

Re: KICK OFF 2 + WORLD CUP 90

Protection was indeed made in-house by Anco. And it was one of the better ones back then as a lot of "crackers" didn't notice the various checksum checks which meant a lot of non-working "cracks" were released. The Cobra X-ROM encryption was neat too for its day, coding the decry...

Re: KICK OFF 2 + WORLD CUP 90

Found this thread by coincidence, interesting disussion here regarding the Kick Off 2 protection... As someone who has cracked "a few" (i.e. all available protected Amiga versions) Kick Off 2 versions I can assure that Rob Northen didn't have anything to do with the protection at all. The ...

What was wrong with the one I sent you a (long) while ago? It works perfectly on my Amiga.

I recognize that i'm not a proggie, but i have quite a lot of knowledge anyway on amiga and less on ST but i clearly see even on the best ST games that we have . That one actually made me laugh. I just read the whole thread and no one here posted as many wrong "facts" about Amiga HW as yo...

It were really 7 voices, just as you say, 4 hw and 3 cpu mixed ones. To get more info about it, you should get hold of Mad Max as he was the one who coded the replay (yeah, Amiga coders got owned by an Atari musician/coder :D). :) Edit: There's a reason that only the intro music used 7 voices, it su...

You can find the player and the module here . For the moment I've included the binary replayer as the source is just a big mess (it was just a quick hack you know), once I've cleaned it up a bit you'll get the .s as well. Instructions are included in my little playersource, just have a look. If you ...

Leonard: I've ripped the TFMX Replayers from Turrican 1 and 2 and I can play the Turrican 2 intro tune without any problem. The only problem is that the replayer expects the module at a fixed address, would that be a problem? If so I'll relocate it but that will take a few days because for that I'd ...

Leonard: Do you still need help with the TMFX replay? If so, I could help you getting the Replayer to work on Amiga and stuff. Just let me know so I don't start hacking around for nothing. :)

Maybe a bit off topic but in the Amiga version you could read this text, hidden on the last track of both disks: IF YOU MANAGED TO GET TO THIS POINT, YOURE VERY PROBABLY A HACKER. BEWARE!!!!
