technically it should be added to emu since ,even though its on android ,you can still play with a controller using a usb to micro usb. Idk though
If you have an N64 and an obscure capture card that can record through your phone, that could happen. Otherwise you can get a cheapo laptop for less than $100 if you don't have a functioning Win/Mac/Linux computer of any kind in the year 2017.
You can practice on Android until you get better tech, though. Practice makes perfect.
I agree with the above. If you actually plan to get a computer, get a good one, if not at least decent. Computer power is usually logarithmic, exponential growth in power. Was making a point that the OP aught to do one of the many things that would count as a normal run as opposed to get an unofficial mobile emu category added.
Maybe you can get Super Mario 63 / Category Extensions to add it, but I heavily doubt it.
If you have 100$ to spend might as well buy an N64 and just play on that. Should be able to find one, a copy of SM64, and a decent controller for not much more than that.
