Of course. There are the Retroarch cores for Genesis Plus GX and Picodrive, both run games at full speed and save fine, plus Retroarch supports savestates as well and such.
But when I go on YouTube the videos are just how to install on like the new updates not henkaku so it might be different and they do it by content manager or is it just a vpk
Genesis plus gx on retroarch?I use Genesis Plus GX with no issues. I'd also avoid using links from youtube videos for anything.
