XRGB-2 Specific Settings
Video is upscanned without problems, however the resulting vertical and horizontal frequencies are not VESA. It doesn't work on some TVs that can't sync with such signals.
The frequency generated by the XRGB-2 when using this pcb is 57.4Hz and it has been verifyied as working on CRT monitors.
XRGB-3 Specific Settings
Works without porblems in B0 mode, however due to the uncommon sync frequency used by System 18 games, the XRGB-3 generates the appropiate upscanned signal at 57.4Hz which might be incompatible with some displays since it is not a VESA compliant mode. It has been verifyied as working on CRT monitors.
