You can wait for the developer response, but here is my thoughts: Of cource there will be an update of the original EmiPSX app, one that me and many others, I think, bought. Currently there is a beta for those who making translations. I received a link to my email, it contains just mine and someone other email, probably
guicholuis96 one. So looks like there will be English, Russian, Spanish and Portugu?s (Brasil) language translations in the next update.
Currently Beta is not supposed for game testing, I have an issues (random spikes around - graphical bugs) with Crash Bandicoot 2 (it is working well on the current 1.0.0.8 version), just for the translation purposes. Maybe Andre will opt some people when he will be ready to fixing gaming issues. I think there is not a problem with sharing Beta
EmiPSX | Windows Phone Apps+Games Store (United States) link - you can only see describing info and can not install it without Andre`s authorization. You may see how it went before - there is a beta
discussion long before app hit the store.
Again, all I listed is my own thoughts. Andre can make it different.
