This session A little background What’s our approach Development details Hopefully time for some Q&A
Who we are
What we look like
What we do
So, you’re developing for the iPhone!

Mobile is challenging Expensive Fragmentation Carriers Backfills
What’s our approach? Target the whole market Hide fragmentation Cost effective development & QA Support new devices from day one
No magic tricks …but close to a silver bullet Scalability is key EMERGE™ Guidelines
Choose your battles Low-end, old devices, coverage
requirements… Good game experience! Touch vs. keys Connectivity & social gaming Future benefits
How do we do it?
Develop the best version Best possible experience Don’t branch development Focus on touch & high-end No limitations!
Target the Other Devices Finish assets Optimize & fix bugs Make sure everything is scalable Get the game down to 64k Help automate post-production
Our tools
EMERGE™ A cross-platform game
development framework Used in 70+ titles 2,000+ devices supported iPhone, Android, J2ME, BREW,
Flash, DSi, Windows Mobile…
The framework Abstraction layer Native implementations of core API Pluggable modules Customizations Improvements help all games
Sample code#include “common.cjavai”#define FP 10
global int_array tileMap;
global void loadLevel() {tileMap = data_getIntArray_TILEMAP();for (int i=0; i<array_length(tileMap); i++) doSomething(tileMap[i]);
}
global void game_paint() {renderBackground();gfx_drawImage_SPACESHIP(shipX>>FP,
shipY>>FP, ALIGN_LT, 0);
}
Handset profiles One for each supported device Contains benchmark data Games and EMERGE adapt
automatically SKU can work on multiple devices

Interpolate!
In practiceStep 1:
SP3_DISABLE_CUTSCENE_BACKGROUNDSP3_DROP_LARGE_EVENT_ICONSSP3_DROP_BG_PROPS
Step 2:SP3_DROP_HIGHLIGHT_FONTSP3_DISABLE_KANJI_GRAPHICS
SP3_DROP_LARGE_TROPHY_ICONS
Step 3:SP3_DISABLE_INTROSP3_DROP_AUDIENCESP3_DISABLE_CAPTIONFONT
...
What our QA does Adjust three numerical “sliders” Possible to tweak SKUs manually
Porting as QA sees itDevice memory <= 300k:
SP3_DROPFEATURES_MEMORY = 10
Benchmarked FPS < 10:SP3_DROPFEATURES_SPEED = 8
Nokia N96:SP3_DROPFEATURES_MEMORY = 1
Samsung ZX20:SP3_DROPFEATURES_SIZE = 8
Porting as devs see it#ifdef USE_LESS_PARTICLES
#define MAX_PARTICLES 20#else
#define MAX_PARTICLES 400#endif
global void drawBackground() {#ifdef DISABLE_BACKGROUND
gfx_setColor(BG_COLOR);gfx_fillRect(0, 0, X_RES, Y_RES);
#elsegfx_drawImage_BACKGROUND(X_CEN, Y_CEN,
ALIGN_HCVC, 0);#endif}
The logistics QA takes less than 1h per handset Over 10,000 SKUs per game Build farm Track submissions & coverage Large-scale DB solution
The benefits Cheaper dev and post-production Better game quality 100% handset support Day one backfills & full back
catalogue support Customizations
The big takeaway? There’s more than the iPhone You can target the entire market
That’s it!
