I just got an official Sega Dreamcast fishing controller and a Yobo Gameware DC light gun. This will be my first time using this type of controllers.

Questions:
1. What is a good game for both of these controllers?
2. I understand the Yobo light gun is compatible with most games, but is it "Silent Scope" friendly?
3. Does it matter about Japanese versus PAL or NTSC/U games as far as what works and what does not regarding the Yobo light gun?
4. Can the fishing controller be used in other games like Virtua Tennis?
5. Can anyone tell me about the Yobo Gun?
