Incredible job, thank you so much, wish you find a way to download it to Xbox. But anyway cant play Genesis games, its says "Developed for use only NTSC Genesis Systems or PAL Mega Drive Systems"
try to add (E) postfix to the rom name
gamename (E).smd' for example
It worked, thank you so much. You are awesome. You should make a UWP Arcade emulator for W10 devices. Like MAME. Of course it will work if Microsoft allow to Windows Store.
