    I like romhacking. It taught me a lot but I think the time has come to move on so I'll leave my IDA file to you. It is the product of 100 hours of work and contains nearly all structures that have been reverse engineered, a huge collection of named(!) functions and tons of cross-references.

    Edit: Link is in the signature

    If you are a serious ASM Hacker I can give you IDA-Lessons via TeamViewer. But basically thats the end of my romhacking-activites.

    Oh wow, this is the last of Knizz's ROM Hacking? Well I'll have to learn how to ASM edit and hex edit. Then maybe one day I might be able to study where Knizz has left off. Hm... IDA, eh? I don't think I've heard about it before.

    Thats a asm Disassembler. Check it out here.

    Its really sad that you're quitting rom hacking. You're a really good ASM hacker.
    But that's your choice, so nobody can force you to continue.

    I've seen your work, and its really huge and well researched, and a work you should be proud of. Now lets hope that the next generation of rom hackers make a good use of it.

    But tell me something, what's that callback functions?What's their purpose?

    With best regards, sonic1

    First. Thank you for actually looking into it.

    The callback functions are functions that are responsible for a certain part of the game and that are called PER FRAME via the "call_back" functions. Callback 1,2,4,5,6 have function pointers somewhere in RAM. Callback 3 is actually a list of function pointers. The most important callbacks are 2 and 3. I talked about them in my "gamemode"-thread. (middle and right column) When I look back I think the naming is stupid. Anyway. When setting breakpoints to find function-offsets in c3. Don't just make a breakpoint on the function that adds a function-offset to the list. Cause not all functions do it that way. You have to put a writing-breakpoint on each entry.

    The link above is a bit outdated because when I wrote it I didn't know that c3
    is a list. Here is the complete sequence of function-offsets in the c3-list during the intro
    Code: 
    If not menioned otherwise these functions are triggered via 0807741C.

    Hey thanks for your explanation. It was very good. Now i understand what callback functions are. It's like a small queue that allows the game to run several things "at once", right?

    And by the way, your research helped me in finding the offset of the new game option - 12Eb2d. You really did a awesome work in rom hacking.

    Im very gratefull to you

    With best regards, sonic1
     
    This is great! It's sad that your leaving pkmn rom hacking, but everyone does sometime or another.
