I need help on The World Ends With You (there's something wrong with the game)

When I start up TWEWY the pin at the starting page is all black and the part where Neku wakes up in the middle of the road everything except for the background is all black. Please help!

I'm using No$GBA emulator

 

Use the latest version of No$GBA, and No$Zoomer.
You can find both in the Common Issues thread.

But I still don't get how it works

 

Which one?
The no$zoomer?

If that's the case, make sure to have the No$gba 2.6a
and extract the no$zoomer files into any folder( to be save just put it into the same folder as no$gba)
Run the no$zoomer, and when it ask to locate no$gba, locate it.

and the emulator will Run normally, the only changes is the screen got bigger than no$gba.

After that Run the TWEWY, and then right click the bottom screen, go to "Extra" option.
and then enable the "EX0" option.

Post again if you still unsure on how to do it.
or have any problem.
