Here's a version of Portal for the Nintendo DS.
The Nintendo DS homebrew scene is - I'm sorry about this one - obviouslystill alive. The robust little community boasts a number of projects, from emulators to ports to full-fledged games, but few are quite as impressive as this pared down version of Valve's much-loved puzzler, Portal.
Sure, the game is looking a bit worse for wear, it has to run on handheld hardware that's nearly a decade-old, but a lot of the Portal staples seem to have made the transition. That being said, the weighted companion cube's fear of elevators seems to be a new addition.
This footage was taken from a version of the game running on an emulator, but according to modder, Smea, the beefier PC hardware hinders more than it helps.
"Also, keep in mind this was shot in an emulator which provides good but still less than perfect rendering," he explains. "As such, be aware that most (not all, but still) of the graphical glitches you can see in this video don't happen on hardware (mostly the portal transition is a lot nicer on an actual DS)."
Smea's previous work includes a handful of finished homebrew games and a basic, but still impressive, port of Minecraft.
Now, I wonder if it'll run on a potato.
