  1. Apparently it is possible to write some ATX files with the Mini Speedy, I have done it, in order to do this before you boot up with MYCopier 2.1 , the one that says US Doubler, you must enable all of the check marks in disk emulation, then turn on the Happy drive window. Then because you have the emulated drives enabled as Happy drives , your Speedy becomes a Happy drive , dont ask me how but it just does, you cannot use Happy software as the two are different, but you can write your disk in Happy mode, whether its because the disk in question is not all that protected or it somehow copies it. I have copied maybe 4 disks that are atx, and they work, I will get a list later on, but this will do until someone writes a proper program for writing atx programs for the Mini Speedy. Russ
  2. Bruce Lee 1984 Datasoft. Cracking this title was quite a challenge for me. I was rather surprised at just how robust the copy protection on this disk was. The main thing that threw a monkey wrench into my plans was the encryption on this disk. It was a strange sort that I’ve never dealt with before. I was never REALLY able to figure it out, but I could modify a few bytes by brute force. The only problem with that attack is that if you modify 1 character, it changes the way the next couple of characters decrypt. The code almost seems to “unravel” like pulling a loose string on a sweater. The second problem with this disk is that some of the sectors seemed to be “double encrypted”. The “double encrypted” section required me to brute force the modifications TWICE! Using Altirra emulator, I used breakpoints to brute force the code AFTER the 1st decryption but BEFORE the 2nd decryption. Once I figured out the 2nd layer encrypted code, I changed the breakpoints so I could brute force the 1st layer encrypted code so it would decrypt to match the 2nd layer encrypted code. All this so the protection routine can do its double decryption with my modifications (and all other code) intact. I actually decrypted the first 3 disk sectors and left them that way, but I didn’t want to do that to the rest of the disk. I wanted the crack to be able to fit into a Chipmunk Plus! patch. The copy protection also checks its own data, in memory and by reading the first 3 sectors a second time to verify the data. This posed a problem, as my decryption and my modifications would be detected. I got around this by storing untouched sector images of the first 3 sectors on sectors 4-6. The copy protection routine now reads the untouched images for data verification. Anyway…here is an .atx copy (with copy protection intact) and an .atr copy (cracked) of Bruce Lee. This also contains my notes if anybody is interested. This crack will also be released on my next update of Chipmunk Plus! Bruce Lee.zip
  3. In my various searches of the internet, I couldn’t help but notice there are many Atari titles that have unfortunately vanished. They are still available in various cracked forms, but finding an unaltered .atx version with copy protection intact can be difficult. Many thanks to the Atari 8-bit Software Preservation Initiative and all the others who have managed to find and preserve all this great Atari 8 bit software. I have a couple of titles to offer for consideration to be “preserved”, which I have been unable to find anywhere in an unaltered form with copy protection intact. Drol (1983)(Broderbund)(US)(Color Version) Drol (1983)(Broderbund)(US)(Black and White Version) Both versions of this game have nice .atx disk images with COPY PROTECTION INTACT. However these are not exactly what they appear to be. These are 2016 REPRODUCTIONS that I have created myself. These images load, look and sound like an authentic Broderbund disk. These images have authentic copy protection, including Duplicate Sectors and Bad Sectors on Track #5 (Typical of Broderbund copy protection). The copy protection functions EXACTLY in the manner that it should, including a subroutine that checks if you are running a “Happy Drive”. The game data is encrypted (just like an authentic Broderbund disk). The titles “crack” in the exact same way as an authentic Broderbund disk. NO these are not “true” disk images but they look, sound, load, etc. the same as a “true” image. If an authentic image is unavailable a good reproduction could “fill the gap”. They were actually made from a composite of SEVERAL clean cracks and some authentic disk images. Using several different versions (instead of just 1) gave me the ability to check the data for modifications. I usually crack Atari software but that gives me an advantage of knowing how certain software companies protect their software. Because I have studied Broderbund copy protection, I know how it functions and what should or shouldn’t be there. The game data for the Drol color version actually had to be re-encrypted. I COULD have used the unencrypted version and just skipped the decryption routine (who would know?) BUT! an authentic Broderbund title DOES NOT FUNCTION LIKE THAT, so neither do my reproductions. (Using Altirra Emulator) I actually used the Broderbund copy protection routine ITSELF to do the data encryption, so I’m quite certain it has been correctly encrypted (so it can be decrypted each time the disk is loaded). This Release Contains: 1 .atx “Original” image of each version with copy protection intact 1 .atr Unmodified backup of each version (won’t boot but shows copy protection at work) 1 .atr Cracked backup version of each title I hope everybody enjoys this and I hope this can be a small contribution to “preserving” Atari Software for the ages! Drol (1983)(Broderbund)(US) - 2016 Reproduction.zip
  4. So I just got my shiny new Kryoflux board yesterday. I got it all set up with an old IBM drive that I cleaned up and it is working perfectly. I was so excited to watch it produce raw stream and .img files of my original Atari 8-bit Bruce Lee disk in less than a minute and a half! I couldn't wait to put in a blank disk and see if it could write a working copy of the disk, protection and all. Then comes the "cannot open image file" error... Did I do something wrong, I wonder to myself? Wait, what? The software can't write back the images it produces??? ??? I have to send them to the "Software Preservation Society" to have them decide if it is worth their time and effort to generate a writeable .ipf file for me? I don't mean to sound ungrateful, because the Kryoflux is truly a remarkable product, but is there ANY way I can build an .ipf file myself with a windows PC? I have a lot of my own data disks; my old BBS disks especially that have become unreadable through the years, that I would like to try to bring back from the dead with this product. Any ideas, links, suggestions would be GREATLY appreciated.
  5. Just wondering - did Infocom have any copy protection on the disks for the Atari computers? I remember back in the day the C64 copied them without a hitch, and no fancy nibblers and such, just straight disk copy. Thanks!
