Help running killer instinct on android

Hello everybody, the title says it all. I have got KI to work on mame4droid reloaded but have no luck with retoarch. I love the game but im kinda dumb so, any help on getting this to work would be greatly appreciated.

I’ve gotten it to work on the MAME core, but it was super slow(1-5 fps) even on my Shield Tablet. It’s running purely in interpreter mode it looks like.

It should work with MAME2010, which uses the 0139 romset and is faster than the regular, up-to-date MAME core, though it still likely won’t hit full speed on a phone.

Interesting. So its not even worth trying if its as slow as mame4droid. I figured since the MK games run so well on it KI would do better. Its all good thanks for the replies.
