Do you ask how I manage a project? I'm using code::blocks IDE. I used this tutorial:
https://whatroidoes.wordpress.com/2...itpro-with-codeblocks-and-debug-with-insight/
However if project grows a bit it likes to crash, but that don't bother me much.
Maybe I'm using less stable version. Some scripts can share same variables so sometimes you need to add "extern" to be declared as something global to both (however is better to avoid if possible) or include the file that defines some functions to the other one that is using them.

this may be difficult to do - NF_VramSpriteGfx(1, 1, 8, false);
if you intented display another sprite on the main screen then you need type NF_VramSpriteGfx(0, 1, 8, false);
If you want to use second screen then you need add things like:
NF_Set2D(1, 0);NF_InitSpriteSys(1); NF_SpriteOamSet(1);oamUpdate(&oamSub);
There's a lot of space in VRAM, but if you plan to fit more maybe this can be helpful

Sometimes games use one of three background layers (one layer is background, second is midleground for paralax effect or game characters, and on top things like status bar or text window, etc. belongs to foreground) and sometimes big side bars are combined from many sprites. (if we talk about 2D engine) On that many sprites in example can be printed text font in text window. (in fact they are used as another one layer). There wasn't any improvement in sprite size comparing to previous generation GBA, but that's how it is. Backgrounds as independent instances are acting like sprites for each other, also you can use one of background as a big sprite.

Also how do you refrence scripts inside of other scripts because your last explanation was very vague, i was asking how to actually trigger another script from inside another one. kind of like a chain

triggering one script inside another one, just one function can call another one, and actually always returns back to the place where it was called. I hope you don't mean something like goto instruction, as is treated as bad practice for this language.
let's say things are simple as this:
void InitializeMore() {
three();
four();
}
void Initialize(){
one();
two();
InitializeMore();
}
main (){
Initialize();
}
...aslo if you would like to do something like this:
void InitializeMore() {
three();
four();
Initialaize();
}
void Initialize(){
one();
two();
InitializeMore();
}
main (){
Initialize();
}
I belive you end up with stack overflow error very soon.

let's say better solution here will be function like void multiplayer() instead of main() (as this one exsists already) doing some things like main loop is doing.
this is intresting:
Code: 
        if(keys & KEY_A & (selection == 1)) {
            MultiplayerMatch();
            return 0;
        }
I see no point in return 0; you can't move main program instance to other one closing previous one like this.
return 0 in main() means exit the program once and for good.
you could here in main loop create something like game modes with switch - case selector and run a function declared in multiplayer() or just move main loop inside a function in other stcript file with posible return back to main menu (main() in main.c). Maybe someone else can have better ideas here.

Not sure what kind of errors but it is required to add every definitions before main() function or at least declarations.
so void Multiplayer() should be moved up.
also multiplayer.h:
C++: 
#include <nds.h>
#include <stdio.h>
void MultiplayerMatch();
multiplayer.cpp:
C++: 
#include "multiplayer.h"
void MultiplayerMatch() {
    iprintf("Printed\n");
}

  • Jayro @ Jayro:
    Eventhough the New 3DS XL is more powerful, I still feel like the DS Lite was a more polished system. It's a real shame that it never got an XL variant keeping the GBA slot. You'd have to go on AliExpress and buy an ML shell to give a DS phat the unofficial "DS Lite" treatment, and that's the best we'll ever get I'm afraid.

    The phat model had amazingly loud speakers tho.

  • SylverReZ @ SylverReZ:
    @Jayro, I don't see whats so special about the DS ML, its just a DS lite in a phat shell. At least the phat model had louder speakers, whereas the lite has a much better screen.

    They probably said "Hey, why not we combine the two together and make a 'new' DS to sell".

    It's a DS Lite in a slightly bigger DS Lite shell.

    It's not a Nintendo / iQue official product, it's a 3rd party custom.

    Nothing special about it other than it's more comfortable than the Lite

    @SylverReZ if you could find a v5 DS ML you would have the best of both worlds since the v5 units had the same backlight brightness levels as the DS Lite unlockable with flashme

    A woman with no arms and no legs was sitting on a beach. A man comes along and the woman says, "I've never been hugged before." So the man feels bad and hugs her. She says "Well i've also never been kissed before." So he gives her a kiss on the cheek. She says "Well I've never been fucked before." So the man throws her into the ocean and says "Now you're fucked."
