What was the problem ?

so I heard that there's a gba emulator using SDL or something (at least I think that's what calc84maniac said before). Will it be possible to port it to nspire?
I'm already porting it (and I removed all SDL references as well, since it's mainly used for the framebuffer)
If I'm thinking of the same emulator, it's written in C++. Do many things have to be changed/rewritten ?

Wow that looks great.  When this is available for download, I need to try the color version to see how this looks like on my CX (assuming a demo of the above is made available?).
Of course!

And here's the source (just ignore my dirty random generator at the end):

Also, please note that the actual code that generates the plasma effect was not made by me, this is just a port of a demo available here.
Trying to recompile the plasma demo, I get an undefined reference to the sinus function. How did you do? Thanks.

The TI-89 has a 160x100 LCD. The TI-92 and TI-Voyage 200 have a 240x128 LCD. But you can run TI-92 Plus assembly games on the TI-89 and their display won't be corrupt. The only problem is that the display is cropped: It means the all those calculators are sharing a 240x128 display buffer, which is partially displayed on the TI-89. All those calculators accept a 240x128 TI-ViewScreen panel, usually used by teachers to show the display to the whole class. In the case of a TI-89, only the top-left part of the panel is used with the OS: In that case, what would happen if an assembly program wrote data in the screen buffer outside the 160x100 zone? Success! Although the game display is cropped on the TI-89, the whole screen buffer is displayed on the external panel.   But of course, this was a VSC version of the TI-89 with the additionnal proprietary ViewScreen connector. The panel can be plugged on every TI-89 Titanium using an adaptator for the mini-USB connector: the TI-89 Titanium Presentation Link. So using this adapter, can this extended display been achieved on all TI-89 Titanium calculators? Success, again! So it's quite interesting! If someone has the time, it means we could develop an external 240x128 display for the TI-89 which would be plugged through the mini-USB port, the 1st step into performing some kind of an "upgrade" of the TI-89 into a TI-92 Plus / TI-Voyage 200. Credits for the idea of the experience go to Lionel Debroux. Source with more information and images: http://tiplanet.org/forum/viewtopic.php?t=9511&p=125807

I've expressed my opinion about such PTTKillers tools only once today, and I didn't intend to argue. Maybe I'm totally wrong, but this is not the point here. Hoffa, I have nothing against you, but your post in the previous thread was allready border-line: http://ourl.ca/16356/305301And the last one above is totally unacceptable on Omnimaga: http://ourl.ca/16362/305390It's insulting and you're showing absolutely no respect towards people who don't share your ideas. You're behaving exactly like the angsty 15-year-old teenagers you describe and maybe even worse... I've reported your post to moderators, and hope that you'll grow up and learn to accept and respect people who don't agree with you in the future. Sincerely.

Maybe, after the mess with the other OS bricking calcs (3.0 iirc?) they're allowing some way out in case something crops up? Yeah, that's the only plausible explanation for OS 3.2.0.1212 allowing downgrade to OS 3.1.0.392: letting users a way out of the bugginess (if any - time will tell) of OS 3.2.
If that's the case, I can assure you 3.2.1 will come out very soon with no downgrade below 3.2 
That will undoubtedly occur ASAP, if OS 3.2.0.1212 proves to be mathematically correct enough: TI doesn't care about our freedom to tinker.
To my advice, it just became more likely to happen sooner after that topic: http://ourl.ca/16356/305241;topicseen#new

Oh no... please... We argued very hard with TI and finally they let us the possibility to downgrade 3.2 to 3.1 and install Ndless... And you release something like this? Do you want another OS update in august/septembre which will block downgrade to 3.1?

Well at least the good side of "official" stuff is that it will work on any Nspire 3.2. Well, sorry Adriweb but it's not my fault if nDoom and mViewer are going to stop working in the next two weeks. And such programs cannot be developped in Lua. You can't present such a limitation as a good side, sorry. ( I mean, whenever Ndless 3.2 comes out, programs for it will only work on jailbroken devices which only represent a tiny fraction of the whole worldwide %) But that's always been like that, for any device.... I take such sentence as quite disrecpectful for people who have worked hard or are still working hard on Ndless. Are you trying to discourage people from going on? For what purpose? TI?

On his TI-Nspire CX CAS, Jim Bauwens is allready running OS 3.2.0.1180!  Don't ask him to send it to you: it's a development OS. It's signed by the development RSA keys and you won't be able to install it on your TI-Nspire which is "normally" validating the OS with the production RSA keys. But don't be sad. Jim just shared the 1st video of a TI-Nspire running OS 3.2. Let's discover together the new Lua physics engine : [ Invalid YouTube link ] More 3.2 informations are available from the TI-Planet news:

Atiatinini, could you please release the source code of your plasma demo?
I think such a simple example would help many people figuring out what has to be changed when porting a PC SDL game.
Thanks.

That's nice to have, but what does it mean for us?
Didn't you read the 1st sentence about hardware mods ? It took the time, sometimes weeks, sometimes months... But most of my (apparently useless) discoveries led to great usefull tools/tutorials in the end  So I think it's a little too early for such a question

Oh sorry, I missed it. Seems we made similar patches.

Summer 2009, the TI community factored all 512-bits RSA keys used to validate OS and Apps installation on TI-z80 and TI-68k Flash calculators. This opened the way to: - patched OSes and Apps
- 3rd party OSes and Apps
Some of the patches disabled the TI-84 PTT mode, and TI must have been bothered with that. Spring 2011, we discovered a new 1.03 Boot Code on the new TI-84 Pocket and on TI-84 Plus hardware revision Q and above. That new Boot Code adds a 2nd validation check for the OS installation with a 2048-bits RSA key only included in OS 2.55MP. So you had to: - wait 6 additional minutes at the "Validating..." screen after sending an OS
- stay with the lastest 2.55MP OS which breaks compatibility with several asm games
Then, Brandon Wilson discovered a way to reflash the TI-84 Boot Code. You could then downgrade your Boot Code to 1.02 or 1.00 and then downgrade the OS. But you had to get such Boot Code image, which is different between basic and Silver Edition TI-84. Brandon then released EpicFail, a Boot Code 1.03 patch. No need to dump the Boot Code on a model you don't own anymore. But you might break your TI-84 permanently if anything bad happends during the Boot Code flashing, and using such tools might void your warranty from TI point of view. Brandon then worked on a 3rd way: a patched TI-84 2.43 OS which can be installed on Boot Code 1.03 because of some exploits. But it could not be shared publicly because of copyright reasons... On TI-Planet we just converted that into a dynamic patch for every TI-84 OS; Make103! You can now make every TI-84 0.46 to 2.53MP OS installable on your original Boot Code 1.03! It also works with TI-83 Plus OSes patched to be installed on the TI-84. For now it doesn't work with 3rd-party OSes which are much smaller and don't reach the 2048-bits RSA key location (and so exploit) in ROM. Download from the TI-Planet news:

In a previous news, we discovered that the TI-Nspire Zevio Magnum ASIC was supporting an external Boot1 NOR chip, present in TI-Nspire Lab Cradles but missing in TI-Nspire TouchPads. Meaning that it could be possible to mod the TI-Nspire TouchPad PCB and add an external Boot1 chip flashed with whatever we want! Did you know that TI developers do sometimes hard-mod calculators the same way hackers would do?  Just check - thanks to Lionel Debroux, we just put our hands on a TI-73 VSC prototype: Nothing really special from the outside? Let's just open it: For one time, it seems we've put our hands on a prototype coming directly from Texas Instruments development team, and not from teachers evaluating it - the proof being that hardware mod around the ASIC chip. What were TI developpers trying to accomplish?...  More and bigger images available from the TI-Planet news:

In a previous news, we had allready introduced you the TI-Navigator Access Point, the proprietary WiFi router used to build a wireless network of TI-Nspire handhelds in class. This evening, let's discover together the DVT1 (Design Validation Tests) prototype of this router - but this time, we're going to open it! On the back, we notice two wifi antenna emplacements, but one one wifi antenna. On the right, we notice power and USB connectors. Let's turn it around: On this prototype, the serial number and the MAC address are replaced by "X" characters. Let's finally open it! The inside of the case reveals two interconnected elements. The first one is the motherboard: Power and USB external connectors are there. But we also notice a strange internal connector in the top left-hand corner. Probably some debug connector similar to the dock connector on the TI-Nspire. Knowing that we allready discovered that the TI-Navigator Access Point is running on Linux, I wouldn't be surprised to find an RS232 Linux console there. But in the end, nothing very interesting on this side of the board... Let's turn it around! This time it's interesting! The board reference is "Nav_Wireless_Bridge_MB_DVT1_6420", with "MB" for "Main Board" or "Mother Board" like on TI-Nspire handhelds. But unlike other Nspire peripherals like the TI-Nspire Lab Cradle or the TI-Nspire ViewScreen, it's not an Nspire board this time. We've got a 16MB S29GL128N Flash ROM from Spansion, but the CPU is a DaVinci TMS320 from TI. Oh did I say 2 elements? Well... did you notice on the bottom the Ethernet connector I haven't mentionned up to now? As there is no such connector visible from the outside, then it's an internal connector. So, to your advice... What is it connected to? Beyond the connector type, there are several other hints in the above images - I'm looking forward to reading your ideas One additionnal hint is available from the french TI-Planet news: http://tiplanet.org/forum/viewtopic.php?p=124594
