Radica SEGA Genesis Audio Issues
We posted an article about how bad the audio is on the "AT Games" SEGA Genesis/Mega Drive.
Turns out there's audio issues on a few of the 'plug and play' consoles out there, which isn't particularly surprising as the Yamaha chip that the console uses is pretty hard to replicate.
However, if you want an actual piece of hardware rather than emulating on a PC then it's a shame that there are so many issues with retro revival consoles.
If you're having issues with the Radica Genesis console, The 8-Bit Guy has done a great video on how to fix the issue.
