As opposed to the Google PlayStore where you have to pay $25 once...

Who spammed downvotes on this without even commenting?
EDIT: Also Spiro, might I ask you to write Nspire instead of nSpire? Nspire is the official spelling. (Proof)

But wait, didn't he say something about updating to nspire_emuv0.70?

Ok, guys here's a nSpiKx_v0.2 update for 'Mountain Lion'(ML) users. I've tested it in my own ML installation and have also received some positive feedback from other ML users.
Please note that nSpiKX_V0.2 is still based on nspire_emu v0.60, which doesn't (correctly) support unaligned memory transfers (UMTs). That has already been fixed in nspire_emu v0.70, but i did not yet made the respective upgrade to nSpiKx. This 'only' means that some games like gpSP will not run in this version, because they depend on UMTs being emulated. However many other games work perfectly well, eg: gbc4cx.
I'm also aware of some 'minor' bugs in UsbExplorer which i'll fix as soon as this ML setback has been overcome. Please note, that this is still a beta-version, specially for ML users.
That's it for now. Please report about any further "black screens".

I think it's in here but I might have misread that?

Okay, cool!
And I'll write SpiroH in the Future *lowvoice*

http://tiplanet.org/forum/viewtopic.php?f=57&t=8698 should help you setting up images suitable for emulators based on nspire_emu, including SpiroH's closed-source forks (even if these shouldn't be used).

Please HELP ME !!! I've got the boot 1, boot 2 and OS 3.2, what I do now ?

Hi AnToX98,
nSpiKx's emulator setup is very similar to kArmTI's setup and also to nspire_emu's.
Basically you'll need:
   1. the 'boot1' and 'boot2' files, which you get from your calc with the 'polydumper' utility.
   2. the TI-OS flash file (you can download either from TI or TI-Planet)
   3. read the first kArmTI Quick Start guide.
I would suggest you spend sometime reading the kArmTI's available documentation, which you can find linked-in the first page of kArmTI's topic. Please take into consideration that for first-timers this is normally a bit difficult. However, many of Omnimaga's young members have successfully done it. Again, you can find a lot of useful info in the kArmTI topic (look at the last posts).
Be patient and you'll get there. Good luck.

Hi again,
You need to create the folder '/Users/Antoine/Library/nSpiKx/TI_ROM' and place all TI files there (Boot1cx.img + Boot2cx.img + TICXCAS-3.1.0.392.tcc) so that the emulator can find them (that's what 'Path' means!).
The app 'nSpiKx' can be placed anywhere, though. I guess this is THE problem!
Also, you're trying to create an initialized OS-Flash file, meaning you'll be prompted to press 'I', etc. So, at this stage it's essential that you look at the console output. Enable the console window (Opt+K) and if you still have problems paste a 'screenie' here.
