Game running slow?

I didnt know how to delete my other thread.

Its running slow, about 38%
Can it run faster? And can the screen be made bigger?

 

what game, what on, etc.

 

I have Pokemon Diamond. OnNo$gba

 

Hmm. Making the screen bigger would only slow it more, and to be perfectly honest, No$GBA isnt perfect.. DS emulation isnt very far yet..

 

Is it possible to make the screen bigger?

Also, I saved the game, and when I tried to reload it, it gave me

The data could not be read. Please turn off power?

 

you need firmware.bin ans set DS backuop media to summit else.

 

Is this for the making screen bigger or the saving problem?
And what do you mean by setting DS backup?
