480x272 LCD with MPRO

[yapen]

Hello!
I'm trying to use Mpro with a different LCD panel. I have a 4.3" landscape Blanview LCD, but it has 480x272 resolution, which is not officialy supported. I have already solved wiring, so all i need now is firmware for lower resolution display.

So, my question is: How can i get MPRO firmware for 480x272 resolution?
