Is there any chance that CBDScrypt will be released in the open? Or at least a 'dumbed down' version that can just search for unencrypted Mastercodes without the threat of giving anything away to the opposition? |

Not in the immediate future. You can try dlong's tool to locate possible master codes. |

I tried using that but, unfortunately, areas it finds to hook into aren't very good for trainer making. It looks like it only finds codes based on one type of hook (not sure which as I've never seen it before) and not SYN, MCR, KEY, IH, etc. Oh well, hope the wait isn't too long for another Mastercode finder. |

who knows how long, but there will be more. |

SYN, MCR? Keypad hooks are going the way of the dinosaurs. They are too complex to locate with much reliability, especially since the hooking in recent code engines is not quite as advanced as it could be. Dlong's master code search locates the ARM7 interrupt handler, although not in the best way. I'll give him some additional information to fix that for the next release. |

I'm not sure what the names stand for but ndsmas by Imaha486 can sometimes find them. For what I'm doing key handlers are the ideal choice. Yeah ARM7 hooking is bad for what I want it for.. Much better to find a place in ARM9. |

Hooking ARM9 is difficult for a few reasons, including: compressed executables, stability issues, and memory management. |

Don't count on any ARM9 hooking in my tool. I don't have decompression routines, and I suck at reverse engineering, so I won't be writing any. |

dlong and cracker if you would be interested in helping I could use a nudge in the right direction. I am interested in making a tool to patch a rom with AR codes (possibly support CB in the future). I want to write a "code engine" similar to the AR's code engine to be used as a general trainer for all roms. What I need help with is how to go about hooking the game in an automatic fashion similar to the AR. If either of you would be so kind as to share any of your information with me or point me to some information on how to get my own custom ASM routine patched into a rom it would be greatly appreciated. |

AR hooks the ARM7 interrupt handler almost exactly the same way Kwurdi has been doing it for about two years. I gave the same information to kenobi for CBDScrypt and to dlong for his master code creator. Adding more than a few instructions to a ROM is a huge task, and requires a lot more than just a simple patch. Namely, making the executables larger, reworking some of the executable sections, and completely rebuilding the ROM file system. If you ask me, it's a waste of time that can be better spent hacking codes or something. |

Then I guess I have one more question. Would it be possible to make a NDS rom that acts like the AR that can be added onto a cart and be booted like the AR but with one difference. You select your game and codes first, then browse your cart for a game to load so that the code engine gets loaded into the memory like the AR and there is no rom hacking involved. I mostly want to do something like this so it is possible to use the trainer toolkit on a rom. I know the trainer toolkit needs the AR engine loaded in memory to do its job, so I am trying to think of the best way to make it work with a rom on a flash cart. I know it would also require some reversing of the AR to find out how it communicates with the trainer toolkit. |

Of course it's possible. |
