How to fit phone screen?

[yuurishibuya]

I know the trick. You don't need anything except win rar and notepad.
Open the app using Win rar. Go to META-INF folder - MANIFEST.MF
Drag it to desktop. Open it using notepad
At the end type these lines

Nokia-MIDlet-Original-Display-Size: www,xxx (Eg. 240,320)
Nokia-MIDlet-Target-Display-Size: yyy,zzz (Eg. 176,220)

Place it back where it was
This worked for me. I just saw that this trick is even present here on game tutorials. But I got this from somewhere else. I don't take the credit

I still doesn't get it? LOL please help
