Problems with some emulators

[Guest lineiron12]

Hi all!

I've tried using some emulators and I've got some problems, how can I solve these?

PocketSNES (both n0p's one, and Bleeding edge)- when I load rom, the whole program freezes, just showing the title screen.

Pocketcultmame - sound works perfectly, but just showing black screen.

Finalburnce - works fine, but how can I config keys?

and one more thing, where can i find the 2.0.3.7 version of Morphgear? I heard the SNES module of its version is fast, and I think i could use both pocketsnes and this one. B)

thanks in advance!
