Hello, I am a newbie here.
I played MAME on PC long time ago. Recently I tried to play MAME on my android mobile phone. But I found that not every rom downloaded here works well.
Here is the detail:
Platform: Galaxy Note 2 (Android)
Mame used: MAME4droid Reloaded 1.1 (I downloaded here)
Rom cannot works: 1943 Japanese version, Commando(World), Street Fighter II' Champion Edition.
The problem is mainly: "The selected game is missing one or more required ROM or CHD images".
Does anyone know how to solve them?
