Sorry if i acted a little rude it's just because so many people misunderstand 3dn file as rom file. I have met so many similar situations like that and had to repeat the answer again and again. For your opinion about the emulation work and the 3dification one, which has a higher priority, i don't agree with it. Nes emulation is over done with hundred emulator. If you just want to play your favorite game, there are many options for you. People want to try 3DNes because it gives a new fresh 3d experience. That's which makes 3DNes different from other nes emulator. That's why i have to focus on the 3dification part first. When it reaches a mature state, i will come back to the emulation part then. If your favorite game is not yet supported by 3DNes then you can always come back later then.
