Negeo and CPS1/2 icons messed up under XMB themes

Hello!

I just installed installed some themes on my PSP with ThemePSP 1.2 ( really like the Mac Theme and one about Megaman Powered Up).

Everything worked fine so far but now I noticed that the icons of four emulators on my MS are shown only black/white and flickering in the menue (ngepsp 0.2.2, ncdzpsp 0.5 beta 3, cps1psp beta 3, cps2psp 1.0).
This happens when I use the Megaman theme as well as the Mac theme, however they look fine when I return to the default theme.

Is there a way to fix this, I really would like to use the Megaman and Mac themes but I also would like all the emulator icons look normal in my menue.

Thanks and greetings :)

the only way to fix this, is to decrease the size of the image

Thanks for the fast reply :)
Which images do you mean, the icons of the emulators or the XMB themes? And which size is recommanded, right now the backgrounds in the themes have a size of 300x170.

Did you install the theme to your flash, or to a DevHook firmware?
