В отзывах пишут что мол звук хреновый

Короче вот:

It's not really a adapter that lets you play Genesis games on the SNES. Technically, all this thing does is use the SNES to power the Genesis clone that resides within the case of the RetroGEN. Compared to a real Genesis the sound quality is off and the video has a tendency to scroll and roll. Also, it uses it's own separate AV cable, not the video output from the SNES. (Like I said, all the SNES really does is act like a power supply) Most people would be better off just picking up a used Genesis.

Видео/Аудио сигнал у этой приблуды свой, как я понял эта хрень юзает SNES чисто как платформу питания и частично (может быть) для логики. Короче хрень
