In Emulators / NES ROMs

I tried to play Nintendo World Championships 1990 on FCE Ultra 0.98.12, but it only shows the title screen and cannot be started, although I have the good NES ROM (Nintendo World Championships 1990 (U) .nes) and the documentation file of fceu names the mappers that are "supported well" and this game is listed there.
What shall I do now? Has anybody been able to start the game with fceu?

I tried it and it didn't start.

It works in Nestopia, though.

Yeah, I found it out: For some reason you have to press the start button of player 2 to start the game.

Interesting... I didn't find that out. I just pushed some keys on the keyboard and it started.
