Just a couple of things I thought might be of interest to some of you DS homebrewers out there.
The first is Pocket Physics, something you may have seen before on YouTube called Crayon Physics, but the DS version has been updated to 0.4 and is available to download from the official site.
The second thing is that Open Transport Tycoon Deluxe has been released on the DS, but is still in Alpha stage, details of that can be found on the OTTD forums.
