Android is upgrading day by day .there are many emulator created like psp ,dolphin,drastic,and now PS2 is fine well .So most of the emulator works fine .Now can you create citra for Android it will get success
As soon as someone feels like putting in the massive amounts of work to port it.
Well, it is not out of question, but the amount of work needed is gigantic. Even if someone works 24x7, it’ll take atleast a few months.
Frankly, no one's interested, as no Android device has enough cpu power to run Citra at even 40% speed. Citra doesn't give full fps, even on most powerful CPUs. First, Citra has to get optimized. Then (maybe) someone, someday, will make an Android version.
