The picture is crazy responsive and clear with the Amiga 1000 I'm using. Something I didn't have with the stock firmware. The only tricky part is soldering the clock generator to one of the pins of the SMD video chip, nothing that a bit of flux and patience won't solve. Another tip is to make sure the ESP wifi antenna is not close to the video chip, the frequencies can interfere.
I need to make a case for mine (still a bare circuit board).
