Random Mode error

[fmfuryfab]

I have an issue where my arduinoboy randomly cycles through modes. I compiled the Code and after several attempts it finally compiled without any Error. I wanted to try it out, but pressing the mode button won't do anything. Sometimes it randomly starts to cycle through the modes and when it comes to MGB i can play notes with my Midi Keyboard and the Green Status Led Lights up correctly. This ist Just temporarely because of the mode cycle. MGB does Not detect anything and I was not able to ever hear a Sound in MGB while I was playing a Note. LSDJ has the Same Problem. Maybe someone knows how to fix it. I have tried several hours and days but I ended writing this text Here. My Setup is a Catskull DIY Kit, a Arduino Uno and a Gameboy Color with Ezflash Junior and the Roms.

It uses a different fork of the code. Use this https://github.com/catskull/Arduinoboy. There's a library for the PS/2 communication that needs to be installed as well on that same link.
