just wondering.
-
No, most likely not. We haven't been able to execute machine code on a CX yet.
-
Once we have ndless for the CX it will probably be started. I doubt its possible in lua at anything more than 10^-25 frames a second

ruler501: It's not just the speed problem, it's impossible, we can't open files in Lua and the whole language just doesn't allow us to make a GB Emulator.

I wish there was more info on ndless, the blog isn't saying much

Usually not_saying_much == not_much_happening. Sometimes it doesn't, but seeing how TI has cracked down on the system and hired new people on the NSpire team to lock it up, I doubt that it means anything else.
-
I remember ExtendeD talking about how they had an exploit, but they didn't want to publish any information on it until they had a second backdoor to exploit in case TI cracks down.
-
The history of computing showed that communities facing the hostility of the manufacturer towards legitimate use of their platforms are better off when they're not too eager to release their software exploits (which the manufacturer is sure to fix in the next release). Remember Nleash: right in the middle of a summer (= low activity period in the community), a previously private exploit enabled bursting out the anti-downgrade protection put by TI in OS 2.1.0.631 in short order. Nleash was a great success :)
The history of computing also shows that all platforms eventually get thoroughly owned, even if the manufacturer did a good job locking them down. That the Nspire hasn't been more thoroughly owned so far is only a sign that we, as a community, are not trying hard enough ;)
-
For Ndless, I find news and activity levels tend to rise after a release is made. It is very doubtful that any specifics will be released now...
-
How DOES ndless work? :P It sounds like it uses a bug in the language to do something or other. I'm just confused at this point. All I know about it is it lets me run machine code such as assembly and compiled C.

Ndless 1.7 and 2.0 use a bug in the OS when trying to open a document, causing a buffer overflow and executing some of our code. Then it modifies the OS code in RAM to intercept when you open any document, check if it's an Ndless program, and run it if so.
-
So, is there any chance TI will notice this and fix the bug? Cause that would suck, really bad.

They already did, which is why we're waiting for Ndless 3.0 ;)

What do you mean "in case"? They're sure to. Their bureaucrats are immune to all forms of logic and reason. They have policy against third-party code, just like Apple. They enforce it. They cannot be reasoned with, just like Apple. They want any programming that happens to happen on their terms. In fact, there's sure to be agents of TI somewhere around here.... Woo! Watch out!

+1 for reference :D

You know, one of the biggest reasons people liked the TI-83/84 is cause of the programming capabilities. So, naturally, they got rid of it

oh, right. Is TI even aware of the calculator community, and websites like ticalc, omnimaga, cemetech, and the like?
-
They probably are, and just don't care. (Probably for some boring legal reason)

Oh, definitely. Until they turned to the dark side, they actually linked to calcg.org and some other sites on their official webwebsite.

TI has become so bad that I'm kinda considering selling my CX CAS and buying a Prizm.
-
Well I guess you may regret it ... but why not buy a prizm and not sell the nspire at the same time.
So you have some time when you have both and can compare them side by side.... ?
-
There's already a gameboy color emulator for the Nspire. Afaik it works on the CX. http://tiplanet.org/forum/archives_voir.php?id=1649
-
It works for all the Nspire 3.1 :)
And indeed, available here : http://ti-pla.net/a1649

THere might be financial issues involved or parents not allowing him to own two calcs. But yeah I would suggest a PRIZM while keeping the CX without upgrading it (assuming you want to keep Ndless)
And yes there's a gb/gbc emu called gbc4nspire as stated above.

@TheNlightenedOne
Prizm dev has been picking up. It's not a bad idea. :) If you need the CAS functions for school though, I'd hang onto it of course. As the Prizm has no CAS.
