Most importantly, they discovered that the clock speed was wrong, which was reportedly the reason the Red Kid 2500 processor had bad audio. Adjusting the clock speed to the correct setting got the sound at about 85-90 percent accuracy of the original Genesis.
Upon hearing this news, fans began messaging TecToy requesting that the company implement this as an official update, and surprising enough, TecToy has announced that they’ll do just that.
Neto and Rafael didn’t stop their work with the TecToy Mega Drive, though. Because it and the AtGames’ Genesis clones and handhelds share the same processor, the two were able to implement this fix on one of their handhelds
