Go with the app MyBoy! It runs everything I throw at it, plus you'll be able to trade or battle through bluetooth and wifi. Playing it on my S7. As a bonus: Download Game Tuner by Samsung, set resolution and textures quality to lowest settings. I'm able to play for 10 hours on a charge.
As with all other hacks out there, you'll have to patch the rom with the .ups file.
Search Google for program and instructions on how to so. If you're on Android just us the app Rom Patcher (Again, Google for instruktions) ;)
Can't really decide on wether to play the current beta or wait for the next release. Yeah, I know, I know.. it's not polite to ask for ETA's, but I'm just wondering if it will be worth the wait ;)
