Kingdom Hearts 358-2 Days on computer emu?

There's a lot of confusing talk about which patches work for what,
and what fixes will work for others. Mostly people talk about their carts,
but if I'm looking to play KH358-2 on a computer emulator, how do I fix it?

I downloaded the patched No$GBA emulator, but that emulator automatically closes after a while for some reason
In addition to that, I'm not sure how reliable the saves are, and I can't change the window size

Is there a way to fix the problems on the No$GBA emulator,
or is there a way to get KH358-2 to work on the iDeaS emulator?

I can't get the game to go past the difficulty screen.

 

Download the addon No$Zoomer to increase window size. You can find it in the Common Issues thread.

The closing issue may be a problem with your computer, what are the specs of your computer? Processor, RAM, Video Card, Operating System.

 

Don't forget you need the 2.6a version of No$gba and for No$zoomer use the 2.3.0.2 version.
To get past the black screen you need a file called firmware.bin in your NO$GBA folder.

 

The specs of my computer are fine, it's a moderately new computer and the emulator runs smoothly
It's just that, after some time, it just closes. There isn't even a window that pops up saying that it closed or why it closed
It just disappears.

Is there no way to get it to work on iDeaS?

 

Never try it on iDeaS but currently the best DS emulator is NO$GBA, maybe there's something wrong with your NO$GBA setting.

 

If your computer is moderately new, try Desmume emulator.
