Gbs_control can be buggy because of the Linux it runs on. As you saw, it tries to log in automatically, which can fail. Also it requires hardware access modules to load, root, etc. On an Arduino, the process is reduced to uploading a sketch and the Arduino will send the I2C commands. Of course, you could simply have swapped the I2C wires by accident ;p
I directly soldered the I2C wires (the GBS board doesnt have any pins on it) and double checked them with a multimeter
Alrighty try this again for lag free capture setup: Component device (if rgb console use rgb2yuv box with audio breakout attachment) -> component splitter amp https://www.amazon.com/1x2-Component-Distribution-SB-3776RCA-ShinybowUSA/dp/B01AQAKTU4/ Output 1 to free CRT off craigslist for playing output 2: to component to HDMI UPSCALER https://www.amazon.com/Portta-PETRHS-Component-Converter-support/dp/B00ATNIFPA/ -> HDMI capture Audio run straight to component2HDMI upscaler or use Y splitter and send to tv as well
Ok so quick update to this: I've noticed a new issue. my VGA to HDMI converter seems to add an ugly green tint to the image. See below. Any ideas why it does this? Is it purely because it's a cheap converter? I assume a more expensive converter would do a better job? Image on my CRT: Image on my HDMI monitor:
