does anyone have any idea how that one group that made the 3.40 custom or w/e, dissasembled all those custom firmwares in to perfect source code?
i have pspdasm 020 by booster and i can view the assembly language version in the command prompt, but i dont know how to save it to a file, and i dont know how to take that and make it in to a source file |

First of all, if you don't know how to use the DOS prompt, you won't get anywhere. To write the output of any executable to a file you use the "> output" option.
In the case of PSPDASM, you'll need to use something like this: Quote: |

Oh, and that is your "source file". You don't need to make it into another "source file", like you implied. It's assembly language - the whole idea of reverse engineering is to disassemble, then re-write the source into a higher-level language such as C or C++. You have to know both assembly and C to be able to do what you want to do.
I'm guessing you don't know ASM, so you may as well just abandon what you're trying to do. |

| Same language, same principle, etc etc. Heh, I <3 it. It's a little difficult to pick up, as it's so inhuman, but after you work with it for years it sort of becomes a second way of thinking, I suppose. |
