Developer Fabien Sanglard has written a code review for id Software's iPhone port of Doom. It's an interesting look into how the original 1993 game (which he also reviewed to understand its rendering process) was adapted to a modern platform. "Just like Wolfenstein 3D, Doom was rendering a screenframe pixel per pixel. The only way to do this on iPhone with an acceptable framerate would be to use CoreSurface/CoreSurface.h framework. But it is unfortunately restricted and using it would prevent distribution on the AppStore. The only solution is to use OpenGL, but this comes with a few challenges: Doom was faking 3D with a 2D map. OpenGL needs real 3D vertices. More than 3D vertices, OpenGL needs data to be sent as triangles (among other things because they are easy to rasterize). But Doom sectors were made of arbitrary forms. Doom 1993's perspective was also faked, it was actually closer to an orthogonal projection than a perspective projection. Doom was using VGA palette indexing to perform special effect (red for damage, silver for invulnerable...)."

An anonymous reader writes "So far, there are over 35 pages of people posting about why EA released Pandemic Studios' final game, Saboteur, to first the EU on December 4th and then, after knowing full well it did not work properly, to the Americas on December 8th. They have been promising to work on a patch that is apparently now in the QA stage of testing. It is not a small bug; rather, if you have an ATI video card and either Windows 7 or Windows Vista, the majority (90%) of users have the game crash after the title screen. Since the marketshare for ATI is nearly equal to that of Nvidia, and the ATI logo is adorning the front page of the Saboteur website, it seems like quite a large mistake to release the game in its current state."

BioWare's upcoming RPG, Dragon Age: Origins, is set to launch on November 3rd. Today they announced details about some of the downloadable content they have planned for the game. In fact, it's scheduled to become available on the same day the game launches, at a cost of $7. (The PS3 version will be slightly delayed). "Called the Warden's Keep, the DLC will add a dungeon-based quest to the game along with six new abilities, a variety of items, and a base where players can trade with merchants. It will feature a supernatural storyline set in an ancient — and possibly haunted — fortress once used as a redoubt by the Grey Wardens, the ancient order at the center of Origins' main storyline." There will be two additional bits of DLC that are available for free to people who have purchased the game new. One "adds a stone golem character to the player's party from the beginning of the game, unlocking numerous story options," and the other increases a character's defense against some attacks in-game.

Neilio writes "What systems would Slashdotters recommend for staying connected while RV'ing across the US and Canada? While a 3G data plan seems obvious, the intrepid RV'er wants to get remote and into those parts of the coverage map that are usually gray (no coverage). But satellite can be expensive, includes high latency for VoIP and gaming, and requires a clear view of the southern sky. I've come across some intriguing products that use an amplified 2G/3G signal and bridge to WiFi, like WiFi In Motion, and CradlePoint's MBR1000 (I have no affiliation with either). Do folks have any experience with these, or can you recommend another approach (even homebrew)? While I am an electrical engineer by degree, you have to go back a few decades since I last expertly sported a soldering iron, so the less DIY the better. My wife and I now run a web-based business, so nearly daily connectivity is a must, no matter where we are."
