I recently bought Retron 77. I went trough hell to get the console. Pretty disappointed to find out that my Elgato capture card can't record the sound from Retron 77. I went trough hell to get the console but If I knew this issue was the thing i probably wouldn't have made the purchase. Even more disappointed Hyperkin doesn't support the console enough to make an update or patch to solve this issue. My last hope was when I heard about the community build for the Retron 77. I went full noob and tried to burn an image of the community build file to the micro sd card using balenaEtcher. That was unsuccessful, error message read; "Unable to record image file, please contact balena Etcher support" ore something like that. Being the noob that I am I used the Retron 77 micro sd card for this. Not only did I not get the community build, now Retron 77 can't even start the menu. I can't even play Atari 2600 games on it let alone record footage with sound. Please help!
