Help Update DaemonByte Fails [Solved]

Hi,

long ago i build a daemonbyte adapter for Sega genesis and it works nicely.
I wanted to update the latest files, but i forgot what i have to use in the Arduino software to flash it.
What do i select as "Board" and what do i choose as "Programmer"?
The Board is connected to COM3. I tried several options, but it fails.
avrdude: ser_open(): can't open device "\\.\COM3": Zugriff verweigert

I made one a while ago, don't remember exactly what settings I used, but when I open the arduino software it's still got SegaControllerUSB open. Board is set to Arduino Leonardo, and programmer to AVRISP mkII. Can't say for sure those are the right ones though. I remember setting the board to leonardo, but I don't think I ever changed the programmer setting.

I couldn't get it to work for a while, and then I switched USB cables and it worked on the next try, so if you're still having trouble try a different cable.

As Yim says, AVRISP mkII works for me too, at least on Arduino Micro boards.

But "can't open device "\\.\COM3": Zugriff verweigert" could mean some other program already opened the port.

I have finally figured it out. I don't have to use the bootloader part. I just have to compile and upload the sketch. I double checked by changing the serial number part in the code. Thanks for helping.
