I finally fitted this board to my 48K Spectrum and it works OK with RGBtoHDMI (In RGsB mode) I have created a profile (attached) but there is a problem: The border is too narrow Here is a screencap from your interface:

Here is a screencap from the analog YUV on the Spectrum edge connector (no bright colours):

Here is the profile I am using for my tests: Spectrum_48K+c0pperDragon.txt

This should be a pretty easy change to make in the firmware. I just used generated a 320x256 pixel total size including border because of the nice numbers involved. If you need a wider image, just tell me how many pixels of border I should add on both sides. I will then create a new firmware for this purpose.

@c0pperdragon Looking at the video signal, the original Spectrum source is approximately 352 pixels wide and 288 pixels high so the border really needs to be around that size in both horizontal and vertical directions to ensure that the video is captured properly in all circumstances.

I have released a new firmware (1.1) for the zx spectrum mod. For programming this with the USB-Blaster, make sure that the cable as the correct orientation on the JTAG header. Pin 1 is on the side nearer the video jack.
