I found mySpire, for those who don't know it, it's supposed to edit the boot images for a unique calculator experience.

Sadly, this only works on 3.1 as stated on https://ndless-apps.org/

However it does start on 4.0.3.29 and i can successfully edit /phoenix/manuf.dat
The changes remain active until i reboot the calculator (reboot / crash doesn't matter)

How comes the manuf.dat file gets refreshed on every boot?

Also is there anyone able to build mySpire for 4.0.3.29?
I have hardware revision J, might that be the problem?

Sorry to bug you guys again, but i really cant figure out why this doesnt work

Here's the important code snipped im talking about:

class Level
{
public:
static bool InitLevel();

private:
static string LevelDataString;
};

bool Level::InitLevel()
{
if(( (Level::LevelDataString).size() % 6) != 0)
{
return false; // This line crashes it all
}
return true;
}


This crashes:
if(( (Level::LevelDataString).size() % 6) != 0)
{
char popup_result[256];
show_msgbox("Error", "The level seems to be broken.");
}
return true;


This also crashes:
if(( (Level::LevelDataString).size() % 6) != 0)
{
return false;
}
return true;


This works (but makes no sense, i just tested if ANY code makes it crash):
if(( (Level::LevelDataString).size() % 6) != 0)
{
int test = 1;
}
return true;

I seriously dont get why i cant just return false from a boolean function ...
I mean, does it crash in "normal" for pcs too or is this just an ndless problem?

Nope im using windows ...
But i have Linux dualboot if that helps me

Hey guys,
sorry to ask you again for something, but this time its that i dont know how to use strings.

Normally strings work like this:

#include <string>

using namespace std;

int main()
{
    string foo = "bar";
}

But this doesnt work, because i cant include the string library ...
Is there anything i forgot to download?
Do i really have to use c-strings?

Or am i just too dumb for this?

ps.: Am i posting in the right forum? I havent found a subforum for such questions ...

<3 you, thx

Didnt think of something like incompatibility.

Thought its all the same with less functions and that c++ compilers would notice if a file has .c attached to it ...

ps.: @Vogtinator isnt it also 2am for you here in germany?

So here's what i have:

I've started a plain c++ project and i wanna make a little game to practise.
Now my sample c++ class test works, and the library sample (nRGB) works too.
But i'm stuck at that point where i want to combine them. It always says something like:

undefined reference to `<every function i wanted to use out of the library>'

I tried this for days now, would be awesome if someone could tell a noob what to do 

Solution:

extern "C" {
#include <nGEO.h>
...
}


I think I have to explain this a little better...


It does NOT connect to an emulator, another ti nspire or anything
It DOES switch Pokemon between two save files:
To trade, do it like this:
1) your friend sends you his savefile
2) You put both your and your friend's savestate in your "My Documents" folder and name them 1.sav and 2.sav
3) start my tool, select which Pokémons you want to trade and click trade
4) send 2_after.sav to your friend


Of course, this isn't the fastest way ever, but it's made for school and there you have time enough.
Also, you must know that this is a) the first c program I wrote and b) the first for a calculator


Normally I code with c# and java (i hate it but in school, we have to do some stupid stuff in a stupid way with it)
edit (years later): Seems like Java is actually pretty cool and the teacher was a retard

Hope it's clearer now, if not, just ask me
