Hey @FreZeeN ,

Thanks for your post.

Raspberry PI has a locked pixel clock so we have to increase the width to compensate for this. 2560 and 3840 are too high for the Raspberry PI to handle. However, its good that 1920 works as this was the initial design. Also the Raspberry PI is not capable of outputting native resolutions,

I will have to look into the new dynamic width option as this should work. It does work fine on Linux PC. This new option is going to change that way emulation works on a CRT as it should work for most video cards.

x-axis centering again works great on Linux PC, I have not got round to testing it yet on the Raspberry PI. This will be the next thing to be looked into.
