You can draw stuff exactly like on the Prizm. The buffer is a 320x240 array of shorts, so you can read and store the pixels directly by array indexing. Basically if you have red value 0-31, green value 0-63, blue value 0-31, you get short color = (red << 11) | (blue << 5) | green;

To get the buffer array, you might be able to do unsigned short buffer[320][240] = *(unsigned short**)0xC0000010; I'm not exactly sure of the correct syntax though.

Wait, is it supposed to be short color = (red << 11) | (blue << 5) | green; or short color = (red << 11) | (green << 5) | blue;???
Erp, you're right. It can actually be BGR or RGB, and the OS chooses the latter.

There is a way to apply for be an "alpha tester"?

What are the biggest issues on the ndless 3.* so far?

O.o I'd be happy to test it on my CX CAS too!  If that's allowed.

Problem is though, I feel like if there are too many testers, the file may go public and others will dive for it...
You just lost the game.

Yeah. Of course, anyone caught doing that would instantly become considered an unreliable jackass and be (morally) excluded from the community for leaking sensitive information and thereby helping all too quickly (*) TI work against our elementary rights as users (do what the heck we want with the hardware we own, because we bought it - for short, "freedom to tinker").

Under no circumstances should an unpolished, unreliable version be leaked. It would be bad for the community's reputation, both in the open development community (users mistaking the unstable version for the real thing, and saying that it's no good) and TI (mostly, some of their pundits on official, or like-minded, communication channels, could easily blame the community for releasing unstable stuff).
That's how it works in other open communities aiming at native code execution on their favorite platform, e.g. gaming consoles, and facing the same kind of manufacturer hostility as we do - and years of experience seem to show that it isn't a bad pattern :)

That said, there is a fine line of balance to be found: too few testers increases the risk to release a product with at least one rough edge, while too many testers might be bad for the reasons stated above :)


(*): the next OS version will certainly fix the holes, even if Ndless 3 is released shortly before the next OS version. TI is very serious about closing the holes, or even the possibility to interact with their calculators through clear-text formats, as they have shown in the past. But giving them more time to close the holes, by releasing raw exploits before there's a companion SDK, doesn't help programmers users in any way - it actually probably hinders them.

Lionel, do you know how many testers are out there?

Very well said, a good idea though is to download os 3.1.0 right now as a backup for when TI blockes ndless 3. Until then be happy that TI at least put in lua, and play around with lua until ndless is officially released

At the very least, now we will have 3D graphing and Ndless at the same time!

I got really hyped when I saw gbcnspire was already ported. :D I totally want to port a SNES emu to this!

I will try to install Ndless 3 in the next few days so that I can report bugs and help. Looking awesome so far.

Well, it isn't out yet :)
Unless you are a Alpha tester, of course.
