Hi there, this video is just for show to developers of RetroArch, the cores "Genesis Plus" & "mGBA".
The most times fails. for me of 100 try
97 times are miss with "mGBA" core
70 times are miss with "Genesis Plus GX"
With the "Fceumm" the miss is 30
With PicoDrive is 40 and
With "Snes 9x" cores, i never had miss with Snes cores yet.
