    Learning NES ASM, Finding a girlfriend.
    I'm thinking it might be a good idea to do to make it easier to edit objects, and stuff. Maybe something good will come out of it like me learning how to make my own objects. Well, just tell me if it's a good idea or a bad one.

    Also, it takes me like 5 min to save in asm everytime I save no matter how small the change is. Pasting can also be a pain in the ass. Anybody know a way to fix it? It'll make doing this a lot easier.

    Don't worry, I won't do post here for every object I do. Just doing this to see what you think.

    After about a dozen people saying you should understand more about this first, you do it anyway *sigh*

    It does no one any good if you have comments that start with "not sure what this is"

    Either way it's better than what we've had before. If nobody else is gonna do it. Then I'll do it. Besides it's probably the best way for me to learnasm. Dammit I can barely seeWTF I'm typing.

    People do comment the objects, but they tend to do it for their own use. Reason for this is that most people who comment the objects actually have some kind of understanding of what they are actually looking at.

    On a side note, how did I know this topic was started by you, just by reading the topic title on the main site? Must be psychic.

    Then I guess I should keep going with it, unless someone is gonna release their version. Despite what you guys think, this is the best way for me to learn. I learn by doing. I can learn by reading, but it's harder for me and it's more of a pain in the ass.

    Never heard him mention it on IRC, since I'm rarely there, but who else would make a topic about commenting objects. It could only be DHZ.

    I'm just trying to help push the SHC forward while still learning things myself.

    I have a very good computer. I was just trying to edit it with a wordpad document. Now I'm using word, it's a lot better now. Also just so everyone knows. I'm not trying to pick a fight with stephen. I'm just trying to prove a point.

    I know you weren't trying to pick a fight, and neither was I. What I was getting at though is that commented objects aren't really much use to people with little or no ASM experience, which is why they never get posted. Full routines like the water slides though are of interest to others and do get posted.

    About the ASM, notepad and wordpad are shit for editing because they seem to struggle with big documents. I use Notepad 2 and it's never failed me yet. It has a handy assembler syntax colour scheme as well which can helpful at times.

    Knowing this part alone is more than useful. Even without knowing asm real well.

    Notepad isn't too bad, but Wordpad and Word are the worst two editors you could be using. I personally use TextPad.

    Wordpad is much quicker than Notepad, however, Notepad2 saves the day. It's much quicker than Wordpad.

    Whatever catches my fancy
    I would say that the unnecessary punctuation gave it away.

    gvim wins hands down.

    dhz: There are several things that you call pointers there that aren't actually pointers. On the 68000 family*, a pointer is an absolute address, period. You're actually referring to offset tables (variously switch tables).




    * As opposed to Intel x86 processors in real mode, where you can have near pointers, which are absolute addresses within a segment, and far pointers, which are near pointers with a segment word attached.
