Hey guys! This is amazing. Would it be possible to, through OneDrive sync this and the UWP Universal Emulator, making it Play Anywhere? That would be amazing, as it would connect most devices.

Hi, I had trouble loading the correct save state. I saved the game at least 2 more times, but when I choose load save, it's still the old save state. Any idea what happened? Is it possible to recover the most recent save state? Does the emulator allow for multiple save states? Thanks for the help.

can someone please help me? None of the states i save are able to load back up, I must be doing something wrong. I've emulated alot on android and pc but for some reason im not seeing a savestate folder or when i try to go do something else on xbox like netflix and come back later to load state it only offers the option to save state. Please help!

Could we.have Atari, intelivision emulators?

First, thanks for developing this, it's awesome being able to play this on a modern TV with minimal effort.

In regards to the Genesis emulator, is there any way to map the C button? I wasn't sure if "only works with the gamepad buttons: ...A, B, X, Y" applied to the genesis games as well. Making sure I'm not missing something.

YO can we please N64 like this?
