As you know, physics is the new 3D. So why not just ditch the 3D for the good old 2D? 2D was much cooler anyways, and a lot of games that were fun in 2D became quite annoying in 3D.

This is where Box2D comes in. It’s a very easy to use 2D physics library with a growing set of features. Box2D got a lot of attention from the game Crayon Physics that showed the potential of the library. Unfortunately, it is not perfect for the DS, because it uses floating point math, which the DS’s CPUs don’t support. So, I decided to create a DS port with fixed point math. Check it out, it’s really easy and a lot of fun!

box2d-1.4.3-ds2.tgz

Update:
The fixed point and Nintendo DS patches are now part of the official Box2D SVN! If you want to use Box2D on the DS, just check out the latest version from SVN. Also, check out my DS physics toy Pocket Physics.

As promised, I’m releasing the source code of Pictoblog. I hope someone will pick it up and develop it further. It should also be pretty easy to use my MetaWeblog API class in other projects.

I would really like to see more blog-enabled homebrew, because I think blogging and the DS go together very well. With the DS you can blog in unusual places (as long as they have WLAN) and in unusual ways (by drawing, recording voice messages etc.)

Get the it here.

If you have any questions concerning the source, don’t hesitate to post in the Pictoblog thread on the GBADev forums!

Have Fun!

There are several small and unreleased DS projects sitting on my hard disk, which are mainly some proof-of-concepts and little demos. I figured they could be useful for some of you, so I’ve opened the filepile, a page where I’ll start posting all these little projects one by one.

The first project is the Spectrum Analyzer app I released some weeks ago. It’s now available from the filepile together with it’s source code, which contains a fixed point FFT implementation and my microphone code I use in NitroTracker and the Sampling Keyboard.
