I'm not obsessing over the 84+CSE. It's actually for people who don't want to buy one but like the interface. :P

If this isn't "promoting illegal ROM distribution" Idk what is xD Nahh I don't mean it DJ_O. But seriously.

I testet the emulator for some time and i discovered some things that won't work.

1. random numbers:

I tested the random numbers and i found out that they where not in the range that is specified.
after a little bit of testing you can see a pattern on calc emu the where in this case the amount of different numbers that can be given (11) + one of the negative numbers gives the number wabbit emu gives me (this is probably the same on TI-84SE).
24->rand
randInt(0,10)
calcemu    9  -6  4  -9  5  0  -1  -1  0  -8  0  -3  -2  2  0  -1  -1  -7  -8  3 
wabbit      9   5  4   2  5  0  10  10  0   3  0   8   9  2  0  10  10   4   3  3
the output on calcemu is the same when you take randInt(10,20) and probably also with randInt(5,15) randInt(100,110) ect.

2. the Solver gives me an ERR: ITERATIONS after a long time of calculating :(




So randint(A,B) returns Plus or Minus (B-A)+1 the actual value that Wabbit or a real calculator SHOULD return?

And there any differences between the original ones and the wabbitemu ones?
The difference is what boot code the ROM uses. The open-source one is good for general use on emulated calcs, but the TI boot code is needed if you want to emulate the calc in a very accurate manner, and I think the open-source one has some kind of issue that prevents it from being used on physical calcs. WabbitEmu is also able to create a ROM with the TI boot code if you provide a dump of the code.
Of course, you're still expected to have a physical calculator of that model.

(In which case you can easily get an accurate ROM image from your real calculator, such as with TiLP or rom8x.)

Not even close. If someone decides to make a TI-84+ emulator that fakes the TI-84+CSE interface in any way it doesn't automatically makes it ROM sharing. You might want to cut down on the trolling lately because if you haven't noticed your total post rating level seems to be going down as days goes by.

I was confused about what you meant with the interface, DJ_O. Nevermind.
Keep trying.

I see many people asking for the emulator's keys. But the principle is very simple and the same as Wabbitemu :
If you want the press the "(" key, you can see that the corresponding alpha key on the real calculator is "K", so you just have to press "K" on the emulator. Of course, some keys don't have any letter corresponding :

menu => ON
ESC => mode
scratchpad => zoom
tab => X,T,Θ,n
ctrl => 2nd
shift => alpha
var => vars
del => clear
"=" => "Y="
trig => Window
"key for some formula models" => trace
book => graph
pi => stats
"?!" => (-)
"flag" => DEL
"newline" => quit the emulator

EDIT : for the parenthesis, you can also use the "(" and ")" keys.

so with this, does that mean the Nspire can have all those extra features that the 84 keypad lacks?

Like maybe nspire people could get mirageOS and those other games that wouldn't work before?

Yes, that's what a usable third-party TI-Z80 emulator means :)
Even if the 84+ <-> Nspire Touchpad keyboard mapping proves a horrible annoyance for those who are very much used to the 84+ keyboard, but on the CX, there's no way around that.

Now this will be interesting. I've got an 84+SE, and I've dumped the rom before, now its a matter of finding it in old documents. And yea, I forgot about the CX, this will help them majorly! Nice job Jacobly! So have we figured out a way to plug say a flash drive into the nspire and read from it?

I have problems running it ???
I have a CX CAS, a 84+SE rom that I initially dumped from my own 84+SE but it is now a save state from Wabbitemu, I put both in the ndless folder (the rom being named rom.rns), then I run calcemu_cx and get a grey screen (with the red bar on top) with nothing happening, even when I press Menu ??? I can still quit fine though.

I own: 83+ ; 84+SE ; 76.fr ; CX CAS ; Prizm ; 84+CSE
