n the DS)• Battery life: With a full 3 hour charge the battery will last 15 to 19

hours on the lowest brightness setting and 5 to 8 hours on the highest brightness setting

• Brighter, more durable top and bottom LCD screens, with four levels of brightness

NDS Homebrew

■ Politics of the Nintendo DS Homebrew Movement most people will never receive the contract with Nintendo Dedicated hobbyists spend weeks reverse engineering the

Nintendo DS hardware • These people make up the homebrew movement

■ Is Homebrew Legal? Homebrew is legal for a number of reasons impossible to publish a game made with homebrew tools

■ The downside of homebrew software pirates often steal from the discoveries of

homebrew

9

Passthrough Device

■ The purpose of the pass through allow the running of programs on the Nintendo DS through the

Game Boy Advance (GBA) cartridge slot or the Nintendo DS (NDS) card slot

The Slot-1 port : DS Flash Cartridge The Slot-2 port : GBA Flash Cartridge

Installing

Installing on Windows• devkitARM : devkitPro updater • PAlib: PAlib Installer

Install it to the same directory as devkitPro .Net framework : PAlib now requires for you to have th

e .Net framework installed Get it here ! that PAlib is not yet compatible with devkitARM releas

e 21 so you need to downgrade to release 20

• reboot your computer!!

11

Compiling Test

■ Emulators No$GBA

• contains almost full NDS emulation support including 3D and WIFI emulation.

Dualis• it works pretty well for home brew, but isn’t as accurate as

No$GBA. iDeaS

• It was the first to support 3d and sound, and... well, DeSmuMe

• maybe the fastest emulator for DS. • doesn’t support sound and zooming/rotation

12

Using PALib With Visual C++

■ Using PALib With Visual C++ 2005 or Express Environment Setup

• DKP_HOME C:\devkitPro AppWizard: Get the AppWizard here

• extract the contents VC8_Express_Setup.js VC8_Setup.js double click

13

Using PALib With Visual C++

■ Building the First Project the “make” tool we use to compile PALib project doesn’t like long fil

ename and directories with spaces

• Tools Options Projects and Solution General

• Change the field “Visual Studio Projects Location” to a folder with no spaces

Execute Visual C++ : File New Select New Project

14

Using PALib With Visual C++

■ the files that were generated by the wizard logo.bmp → this is the image your app will sho

w in DS Loaders. logo_wifi.bmp → the logo to use with WiFi. main.cpp → the main program file, with some c

ode already written for you. Makefile → a PALib makefile optimized for Vis

ual Studio. ReadMe.txt → some info.

■ Add Include Tools → Options → Project & Solutions → VC+

+ Directories select “Include files”

• <path to PALib>\include\nds• <path to PALib>\libnds\include

■ Bulid F7

Using PALib With Visual C++

■ Compiling Error 1 Invalid conversion error

C:\devkitPro\PAlib\include\nds\arm9\PA_Sound.h add (u32*)

16

Using PALib With Visual C++

■ Compiling Error 2 File Open error

C:\devkitPro\PAlib\lib\arm7\arm7.bin • add arm7.bin current project folder

17

Setting Up an Emulator inside Visual C++

■ setup a NDS emulator as an External Tool Click on “Tools”, “External Tools” click on “Add” to create a new External Tool

Command: Select NO$GBA.exeArgument: TargetDir)\$(TargetName).ndsInitial directory: $(TargetDir)

First NDS Programming

■ Template's Main Code

// PALib Template Application// Includes#include <PA9.h> // Include for PA_Libint main(){

PA_Init(); // Initializes PA_LibPA_InitVBL(); // Initializes a standard VBL

PA_InitText(1, 2);PA_OutputSimpleText(1, 1, 2, "Hello World!");

// Infinite loop to keep the program runningwhile (1){

PA_WaitForVBL();}return 0;

}

20

First NDS Programming

■ Decoding the Code ! #include <PA9.h> : include PAlib into my code int main(int argc, char ** argv) : the start of your program PA_Init(); // Initializes PA_Lib

• a general initialization PA_Lib PA_InitVBL(); // Initializes a standard VBL

• VBL(Verticle Blanking Interrupt) synchronize the program with the screen, at 60 frames per s

econd If you don’t initialize the VBL, either the program will work w

ay faster (like 100000 frames per second, which is unplayable) or not work at all

21

First NDS Programming

■ Decoding the Code ! PA_InitText(1,2); //Tell it to use text on screen 1, background number 2

• Argument 1: screen (0 for bottom, 1 for top screen)• Argument 2: background to use

0 for topmost layet, 1 for next, 2, and 3 for the bottom PA_OutputSimpleText(1,1,1,"Hello World !"); //Print the text on scr

een 1

• Argument 1: Screen (0-1) • Argument 2: Horizontal (X) from which to start (from 0 to 3

1) Each tile is a 8×8 pixel square

• Argument 3: Vertical (Y) (from 0 to 23)

• Argument 4: Text While(1) { PA_WaitForVBL(); }

• synchronizes the infinite loop (60 fps).
