Why cant I see the font/some game screen.

I have an n95 nokia phone and i cannot run Pokemon Sapphire Version (GBA) because i start it i see the intro perfectly, but when i get onto the "main menu" i only see black dots and some parts of the blue pokemon, when i press buttons ( not knowing what they are ) i see a white line with a red arrow, im guessing the white should contain some font , but either the font is also white so it doesnt show up? so i dont know what im pressing? any help?Bassically i cant see the game correctly.

The emulator's fault most likely.
