Can't get this one game to play in NES A.D.X + emulator

[Jimieo]

As the title says I'm stuck with this emulator. I'm trying to play Nintendo World Chapionshop game (from 1990) on my iPod Touch 4g. However this one rom will not load past the load screen. It works in PC emulators I have. Does anyone know of the most up to date emulator for iOS? I tried to load their web site to ask questions but bslapps.com is no longer running.

Any help would be appreciated.
