gpsp tweeking?

I'm not whining so don't blaze me people but is there anyway to remove the bios from the rom list or change the background of the gui? I mean it seems kind of weird that these coders spend all these long hours to share there work with us but leave out some minor lines of code that would make the emulator seem more polished and match the rest of the psp's good looks. and yes I did look into programming to try to tweek these emulators but I soon found out that I am not smart enough. btw I do have some other emus looking good Its just the gba and snes emu that are still looking homely.

open gui.c with your IDE of choice scroll down to line 930 and edit out the extension you don't want and recompile.
