To do Frame Perfect wallkicks, you would need to be on drugs or a robot.
I would think If an Android CE were to be established, it would be something like using touch screen controls.
you're talking about 3d all stars, you'll want to go to https://www.speedrun.com/sm3das about this.
iQue has their own leaderboards, so not a great example to use (https://www.speedrun.com/sm64ique)
for talon star you can use the pyramid star strat and just use Silly kicks to stay up near the tip of the pyramid to stay up there till the bird comes and you fly right into you
to do RTA hyperspeed wallkicking, you would need to be on drugs. and you can ask about possibly getting a category extensions page made
If its ran on 3DAS it cant go here. but you could try talking to a moderator of 3DAS about category extensions
I feel like Homebrew could definitely be developed to allow inverting the analog sticks
I would recommend getting a tripod instead of propping a phone up on something, so there isn't a chance of it falling and possibly invalidating your run
the version of sm64 on the 3d All-stars is Shindou, and emulation. VC has a Classic Controller screen upon boot up which is timed since the timing method is RTA and Start timing upon reset meaning n64 and vc would be unfair to be timed together hence the split in the leaderboards.
and iQue Sm64 is different im pretty sure they patched things in it

I don't use n64 personally but have knowledge in the world of video outputs so i could help. so do you want to split the svideo signal or convert it to composite then split the video signal
