The only complaint I have is there seems to be a bit of button lag. It's not a lot, and it's not even noticeable in most games, but it makes games such as the Super Mario RPG Series (such as Partners in Time and Bowser's Inside Story) nearly impossible to play because all the maneuvers (especially during battle) are very timed.

An great all-around player. I had an issue with a Pokemon Silversoul game for DS. I could not get game to work after beating elite four. I had an issue with a communication error that would not go away after ending credits. I am finding out it is something to do with bios files, DS wifi, and editing save files. MegaDS 16 solved my issue of finding a reliable DS emulator until this. I just switched to MelonDS as I have read this emulator app solved these issues. Thank you for the decent product.

Much better than all the other ds emulators that I have tried, play is smooth and very reminiscent of actual DS play.

Thank you so much for the 5 stars! We're thrilled to hear Mega3D gives you that authentic, smooth experience. Don't forget to use decrypted files (.3ds) for the best performance on 3DS games. Happy gaming! 🎮
