VAUS Support for NES (e.g.Arkaniod) / Feature Variable Sensitivity & Mouse Buttons
First of all thanks for the great project. I just wanted to ask if you have managed to get the spinner working for NES Games like Arkanoid on a Mister FGPA ? I tried all 3 Modes, but the Core does not accept Spinner inputs (Button A works)
Also, I did some minor modifications to get these 2 Features working:
- MouseX Mode: Button 0 and Button 1 act as Mouse Left/Right click,... very useful for Atari Games like Krypton Egg
- MouseX & Mr-Spinner Mode: Button 2 and 3 lower/rise the Mouse/Spinner sensitivity.
Here's the code.

thanks for making a fork @nad22 - I tried to flash it to my arduino but got a missing file error (whereas this original branch flashes fine). I couldn't open an issue on your repo tho. Are you still developing your fork?

Hi! I activated issues,. feel free to post your compile errors,.. i am looking forward to help you. Kind Regards !
