Yeah 4 bits actually, although in TI-BASIC, unsquished form, it would be more like 8 bits instead of 16.

The custom palette feature would come to the rescue so maybe some map data could even be reused for multiple dungeons like in Illusiat 11.

So I just got my TI-84+CE and only a few seconds after turning it ON I ran into a funny bug: Basically, if you perform a full memory reset, it says RAM Cleared instead of Mem Cleared O.O


Also, some stuff to know about TI-BASIC: It appears that strings cannot be larger than 32768 characters. I haven't tested with 2-byte tokens, though. An ERR:UNDEFINED will be thrown when attempting to concatenate two strings that exceeds that amount when combined.

Fun fact: Memory means RAM:P its a common misconceptions that memory means storage aswell :)
though i guess it should say "storage cleared" or something

Yeah I meant mem as in both RAM+archive.

EDIT: This is an edited CSE screenshot of about how fast a graph grid (in line mode) can render:



This could be handy for some animations (eg magic) in pure-BASIC

EDIT: New screenshot with the right frame rate.

Good news, at first glance, it appears that hacked pic vars still work on the TI-84+CE!

With the BASIC program included with http://www.ticalc.org/archives/files/fileinfo/279/27979.html , you can have up to 255 pictures. But I don't think you can send them between calcs.

Yay for Kevtiva making it possible to have 255 pictures instead of 40 15 years before the calc existed. :P

Yeah it's TI Smart View. But it's paid (I have a 90 days trial from TI website) and it doesn't emulate undocumented ASM instructions, so games that utilize special modes like Pacman CE does will not work properly. It's also ultra-laggy. (sometimes freezes for 5 seconds when I press like 3 keys in less than 2 seconds)

Sounds TI :P
Could you translate your post into English so that I can understand it?

Thats what you get for emulating a 12 Mhz CPU in Java <_< it's a fine language, but its not made for that.
They should have used C or something. Also i looked a bit at the code and they use a lot of JS too (since java has abuilt in JS scripting engine). Wouldnt suprise me if
they run an emulator inside JS inside Java <_<

I think he meant that it is normal for Ti to sell you something that barely works or laggs allot :P

On top of that they're charging money for it O.O

I bet they would be open to porting it to C or another faster language, but I doubt they'll bother paying staff to do it. It's a shame because the emulator from TI actually has some nice features, such as being able to see the graph, homescreen and table windows all at once.

No no no.
The problem (slowness of the emu inside SV) isn't coming from the fact that the emulator is written in JavaScript, nor the fact that the SmartView itself is written in Java.
The problem is that Java's webview has a bad/slow(er) JS engine in its WebView (compared to the standard set in modern browser, with insane JS "compiling"/performance, so to speak).

As said earlier, if you extract the .js and try the emulator core (the .js file) in Chrome, FF, or whatever, it runs fast. Too fast, even (2x-5x the real calc's speed). I did a benchmark on that earlier.
They chose JS as the implementation language of the emu core, and that is clearly not an issue.

Now, if only they can bypass Java's crappy webview and embed v8 or similar, it'd be great. But I don't see TI doing that, as the current speed is already acceptable for teachers (it is faster than the directly native (C++ or C# I think?) emulator previous versions (the 84+ SV)

Oh I see now. That's definitively weird. And yeah I doubt they'll bother doing it. That said, I could see teachers asking for a faster emu if the slow key detection gets in the way. When I type fast, the emulator freezes for a few seconds because key input seems to make the emulator take a considerable amount of CPU resources.
