Wait a minute, in those screenshots I'm seeing OpenGL calls? The only graphics programming I've done is OpenGL (doing my second semester of it now). In all of the DS homebrew tutorials I'd breezed over, I saw no mention of the ability to use OpenGL, just some sprite stuff, which doesn't really interest me.
So anyway, can I run OpenGL stuff (very limited, of course) on my DS?
I finally gave in and downloaded a bunch of homebrew stuff tonight (took a while to find my old Quake CD for the pak files though), and man it's sweet. I found that Quake handles better than Metroid. The older, more simplistic gameplay makes precise accuracy/aiming with the stylus much less of an issue. It's a pity the developer seems to have abandoned it without adding ad-hoc games, it'd make my computer ethics lecture so much more interesting. Looks like the Quake 2 port (same guy) has been abandoned too. Ah well.
At the bottom of http://quake.drunkencoders.com/ he's got a short gameplay video of what he'd done on Quake 2 (it's running like shit, but he said that's how Quake 1 was initially), but the last comment from him in the linked video is him saying he just can't be arsed doing it anymore. It made me sad.
It's a pity that QuakeDS seemed so close to completion too, only a few more things needed to be added/fixed. I suppose it's easy for me to say "only" a few things when I'm not the one writing the software. Oh well, it does the job for now.
Edit: what's the best homebrew app for listing wifi connections (and their signal strength) in the area? There were a couple of links to some programs ten pages back, but that stuff is months old, and there's a new DSWifi package or something, so I'm not entirely sure if they're still the best. Not looking for anything else in the program, just the ability to check potential connections.

I hate to ask questions that seem obvious, but before dropping cash it's kind of nice:
From what I understand, R4DS does NOT come with a microSD card in it's main package. Sites seem to bundle it with a microSD, so it seems safe to assume it does not come with it by default.
Why I'm asking is my boyfriend got a 25 dollar gift certificate for Amazon, and while the R4DS is WAY overpriced there, I can get a microSD card for pretty decent.
I hate to ask questions that seem obvious, but before dropping cash it's kind of nice:
I think that the only mainstream offering that comes with built in memory is the G6, so as far as I'm aware, the R4 doesn't come with its own expandable memory. I'd say you may as well snag the microSD from amazon if you can get it cheap.
Just a quick update on the raytracer before I pack up and head out to Otakon this weekend. I've got it nearly matching what I'm rendering on the PC (though it takes orders of magnitude longer to render) ...
That's amazing, I haven't seen any projects like this on the DS. How does the program work exactly? I know dick all about ray tracing, other than it has something to do with rendering. Are you using OpenGL to draw the scene, then your ray tracing stuff to render it?
All this DS homebrew stuff has my dick rock hard. Once this wave of assignments at uni has passed I'm gonna try porting some of my OpenGL stuff over to it, if I can find some decent OpenGL for DS resources.
There's a setting in the .ini file that let's you use the touchscreen to select games.
Also, www.r4ds.net is the English site, but you can still go to www.r4ds.com and look in the bottom left to get the Kernel.
Are you referring to the FileSelectSubScreen setting in moonshl.ini? I tried it and it only affects the file selection in moonshell, not the main game selection. Did you really get the game selection to work via touchscreen?

has anyone managed to get it to work?
The R4 doesn't use the touch screen for game selection. It's direction pad only for moving the highlighted game/directory. You CAN use the touch screen to start a selected game, but I find it easier to just use the A button. Pressing L/R will Page UP/DOWN to make navigating a bit quicker.
So I'm looking at getting into some homebrew with my ds, what do you guys recommend for the flash carts? Do they make one that sits flush with the lite, so it doesn't stick out the way a gba cart does?
So I'm looking at getting into some homebrew with my ds, what do you guys recommend for the flash carts? Do they make one that sits flush with the lite, so it doesn't stick out the way a gba cart does?
What do I need?
A homebrew device, which is basically a cartridge that you can write stuff to. These come in two types, slot-1 devices and slot-2 devices.
Slot-2 devices plug into the GBA slot and have either internal memory or a space for a CF or SD card. To run DS homebrew off of them, you also need a special card called a NoPass in the DS slot, because otherwise the DS would just boot into GBA mode, which is not nearly as cool.
Slot-1 devices plug into the DS slot and usually have a MicroSD card slot on them, although a few exist that run with built-in memory and a mini-USB jack or something. You can't run old GBA homebrew off of these, but you don't need to screw around with NoPasses, either.
As of today I am the proud new owner of an EZFlash V, which is a slot 1 device, but this particular model comes with this nifty expansion pack that I can write GBA homebrew to. This expansion pack also claims to function as a Rumble Pak (for rumble-enabled games) or Memory Pack (for the DS Browser) but I have nothing to test that with so I can't vouch for that.
I use an EZFlash 3-in-1 in my slot 2, for GBA homebrew. I have an R4DS in slot 1, and the 3-in-1 loads the GBA games from the MicroSD card in the R4DS. Yes, the rumble and memory pack functions work just fine.
My GF got up to like four hundred and then the battery died. It's not hard: the block speed slows every time you get a word.
While I was able to get the arcade mode within few tries (at 99 words), I still can't get anywhere near your gf or my gf's lvl. Just last night, she got into some amazing rhythm and scored over 970,000 points with over 1100 words! (Luckily, the DS was plugged into the AC adapter.) And I only got her hooked on it a week ago! I haven't been even been able to reach near my 99 word high score, which has now been wiped off the high score ranking list. She did get frustrated at how long it took her to lose, so she says that she'll stay off of it at least for a while. Hopefully long enough for me to get my DS back and finish Luminous Arc.
One thing I still haven't figured out with my R4: when in the initial menu, what does the circled R mean in the upper right hand corner of the lower screen?

I swear I feel like I'm the only honest person anymore. I work at a CompUSA, and out of the 6 or 7 people that own DSes in the building, I believe I'm the only one that doesn't have a flashcard.
Me: "All I buy is DS games pretty much anymore..."
Co-Worker: "You still buy DS games?" (Refering to his Flash Cart)
Ok wow....all this stuff looks really, really awesome....
The only problem is that I think I am clinically retarded. I dont understand anything that has been going on in this thread besides me going "OOOO that would be fun!"
I really, really want to use my DS as an MP3 player, but some of those homebrew games/apps look pretty darn sweet. (Specifically, the AIM for DS, Colors, and the Email thingy. Also a bunch of games)
Can someone give me a really simplified version of what I need to get/do to be able to use some of these goodies?
This is my understanding so far- All homebrew apps (Such as Colors and DSAIM) are saved on an SD card. in order to USE those you need to install some kind of program onto your DS.
Arch's brain's example: WOO music! I have Katamaritheme.mp3 on an SD card. I install something onto my ds, slide the card into something else so it fits, and BAM i can listen.
I swear I feel like I'm the only honest person anymore.
While there probably are a lot of people ruining things by getting these cards for piracy, you are not only posting on a wrong topic, but you are insulting us. This thread is about homebrew. These are games people write for personal enjoyment that they release to the world for free. There are plenty of us who actually enjoy coding for the sake of coding, and that's what this is all about. Look at open source efforts for example. Even though many tools are better than what you can purchase, the developers give 'em away for free.
I do not own any pirated roms, and am still buying games (Luminous Arc as stated above being my most recent purchase for DS - Just preordered the new PSP and Loco Roco for PSP.) I have owned 2 PS2s, not because I screwed up a modchipping job, but because first one died of the Sony's pre-maturely dying lasers.
By trying to make yourself the "saint," you have falsely accused us of piracy. Honest indeed. While the DS is my first experience with homebrew scene on the console, I have lurked various forums long enough to get sick and tired of comments like yours.
Now back to the subject: what are some of the current websites with news regarding DS homebrew? With the exception of few games, I think I'm pretty bored with the games already mentioned, and am looking for something else to try out. Has anyone gotten DSBlue to work with wireless networks? Mine locks up everytime I try to do anything wireless with it with homebrew stuff.

Unfortunately, the only good tracking sites I know of for homebrew ALSO track rom releases - but since they do NOT provide download links for those, only notifications, hopefully mentioning them here would be okay. If somebody can confirm for me that it won't be a problem, I'll be happy to share.

Not retarded at all man. I'm no expert but recently got an R4DS which makes what you specifically want to do fairly easy. Here's how it works as I understand. (Others feel free to correct me, I'm a DS homebrew newb) The R4DS is a DS game cart sized device that has a micro SD(? I forget the exact type) card will fit into. The R4DS comes with a disc that has a program called moonshell on it that will allow you to launch homebrew application (files ending in .ds) on the DS or play media files such as MP3s or specially formatted movie files. Basically you load up the micro SD card on your computer with the files from the included CD for Moonshell, then the specially formatted homebrew files (.ds for homebrew games/apps, mp3s for music, or the specially formatted files for video) then put the micro SD in the R4DS and then put that in your DS. Start up the DS and Moonshell will be loaded for you by default. Select what you want to do from the interface screen and go. Pretty simple really.
This is some pretty cool stuff. I just have a DS Fat that I use for toilet Minish Cap these days, but I've been thinking about getting a DS Lite at some point. Maybe after the onslaught of awesome PC games dies down a bit. It would be nice to be able to play MP3s and stuff, also the organizer looks handy. Is there no homebrew web browser?
How well does the program that lets you play old adventure games on the DS work? I think I have a copy of Full Throttle somewhere and it would be fun to play that on the DS. Would Grim Fandango work? Probably not I would guess, but it would give me an excuse to track down the Monkey Island games.

Full Throttle and Curse of Monkey Island don't work. Grim Fandango is not supported by the SCUMMVM project, and even if it were, the DS wouldn't be able to run it, unfortunately.
It's a shame the Humongous Entertainment games don't work either. I loves me some Freddi Fish and Putt-Putt.
I picked up the EZFlash V bundled with the 3-in-1, and I love them so far. The homebrew apps/games are pretty cool. Its not terribly difficult to set up, and I recommend anyone who gets an EZ Flash to look for the official forums for instructions on setting up the card.
Basically, you format your microSD as FAT32. Load up the Shell, and then update the kernel. Once thats done, find DLDIrc with the appropriate driver for your flashcart, and use that to patch the DLDI in homebrew apps/games. Any app that writes to the microSD card will need to be DLDI patched. If they simply write to a save, you don't need the DLDI patch (and applying the patch will just fail, no damage done.)

I don't think homebrew can write to a save. It's either DLDI or no read/write.

It is?
In any case, you'd need a slot-2-only device to do it, which would be a bit of a waste after already buying an R4.
