I decided to create this topic because too many questions were often asked on @ oroborus77's Lightgun Crisis topic
He did a lot of work on his Lightgun Crisis box and the topic was redirected too many times to something on wiimote issues.
So as a starting point you can start by taking a look at my channel on youtube:
There are many tutorials on how to play wiimotes as lightguns.
Anyone wishing to share their knowledge of wiimotes as light rifles are welcome!
And please, if you have any questions about wiimotes, feel free to ask them here right now. Thank you!
