SuperN64 works great and is a little faster than Mupen64Plus AE Free.
Recently,it has mysteriously vanished from the Play Store and all other app sites like wandoujia,appchina,and voga360.
The only other mainstream app store that has it is 1mobile,which requires the 1mobile market app since they started forcing you to use it instead of directly downloading the app from the webpage.
Trying to do that results in the app file being the market instead of the app you choose.
You will need the orientation to be forced landscape to correctly view the app.
Here is one place SuperN64 can be found as a direct download.
SuperN64 has normal ads and video ads only when exiting it.
It asks you to rate it every so often,but that does not bother me enough to quit using it.
You can cancel out the video ads simply by hitting the Home button.
The 1mobile link as well...
Stars and random x to avoid BS.
