In the distant past, the Address Book app in Mac OS X Tiger could send mobile SMS messages directly from within the app, if you paired your mobile phone with your Mac via Bluetooth. Along came Leopard, and the feature mysteriously vanished without trace or explanation, and hasn’t reappeared since. Missing the feature, I found a roundabout replacement in the emitSMS dashboard widget. It offers SMS sending via Bluetooth and can also search the Address Book for phone numbers. Having seen that the source code for emitSMS was released, I adapted the backend into a plugin for Address Book.app to provide the missing former functionality.

Here is a project I’ve been working on for a few weeks to learn more about DS homebrew coding. It’s a remake of Deflektor, an old puzzle game that I played on the Amiga. I’ve tried to keep the retro feel of the original while updating it to use the touchscreen interface.

The aim is to rotate the mirrors () to reflect the laser beam from the source () to blow up all the triggers () and then enter the target (). Rotate the mirrors by tapping on them and then dragging to align the mirror at a particular angle. You start with an amount of energy which is constantly declining (the green bar). Directing the beam into a spike () or reflecting the beam back to the source will cause it to overload (represented by the red bar). If the source is overloaded too much or if you run out of energy, you lose a life. There are also rotating blocks which only allow the beam to pass at a certain angle (), teleports () which work in pairs, and blocks which randomize the beam direction (). In addition, in some levels there are gremlins which roam about the board and mess with your stuff. You can get rid of them by tapping on them repeatedly.

I’ve built a Mac (Intel) binary of DesMuME, from the latest SVN code, with a patch to enable masscat’s GDB stub. With it you can load a homebrew rom, connect to DesMuME with the copy of GDB that’s provided with devkitARM, and start debugging your homebrew code while it’s running in the emulator.
