I am thinking about this specification. When connected to the BemRacer, there is absolutely no improvement in image quality.
The image is identical to that of the VIC-II itself.
Hello and welcome to the forum!
In its default configuration BeamRacer does not affect the analog video signal generated by VIC-II. To enable LumafixPro, please locate switch SW1 in the lower-right corner of the board, next to "LUMAFIX ON" marking. Enable the switch by removing orange protective film from the top and then move the knob to the right, using a pin or a needle.
It is safe to do it while the C64 is powered on, and the difference in image quality should be immediately obvious.
Next, please use trimmers PHI0 and AEC to fine-tune the circuit to the specifics of your VIC-II, motherboard, and analog-to-digital video converter (if in use).
