Depends only on what direction you and the team want PPSSPP to take. You thrown the emu on android platforms almost immediatly after the first public release, almost stating boldly that Android was one of the team target platform.

The success this wonderful piece of code on android proved you right Smile

Fact is: Snapdragon CPUS are slowly begin to be "THE" hardware on androids (like Apple SGX ecosystem). S4,S600,S800 and S805 are basically being adopted from every brand, even chinese cheap ones such Lenovo, ZTE, Oppo and so on.

Which means that Snapdragon will be the baseline of Android devices in the future. Unfortunately afaik the NEON performance is something lacking even in S800, same will be with newer S805.
Same happens with S200 and S400.

This leads to me to think: is safe to not further optimize PPSSPP code because it will require a huge amount of work (like you said), by not implementing Thumb-2?

If that optimization isnt take into account, what will be the android version future, when snapdragons will be the largest machine base out there?

Questions questions....point is that Software Skinning proved that boosting performance is something that can be done without rewriting the whole code, which is awesome.

If is true that further optimizations can be done, i think we can stay with what we have right now. But as far as the optimization goes, decisions needs to be taken. In the future, which is approaching fast (as soon as Q1 2014 kicks in, we will see a flood of Snapdragon devices), what will be of ppsspp android?
