I just got a FXPak Pro and wanted to try Game Boy games on it. I read all of the instructions and got everything to boot up fine, but I'm experiencing some weird screen flickering with white lines. I'm not really sure how to describe it, so I recorded a little video of it. As you'll see in the video, it's really bad for Game Boy games, but I do notice a flicker here and there every so often when playing SNES games. I barely notice it while playing SNES, so I'm not too worried about that. I'm playing on a CRT through composite connection. The CRT probably could use a recapping, but it really only seems to be Game Boy games that flicker as bad as it does. Is this a known issue that other people are having? I didn't really see anyone else post anything about it.
Here's the link to the video that I recorded.
