Final Fantasy IV : The complete collection

[Igneel]

I've been playing FF4 on PPSSPP, and I've been able to go in-game. In fact, I've been playing the after years for quite some time, and even reached the final dungeon. You just need to tweak the settings, and you should see something going on. If you're using the most recent version, I recommend turning the rendering mode to Non-buffered rendering, and enable vertex cache(disable everything else in the "features" category). Then, in the system category, enable fast memory and dynarec if it isn't already. These are the settings I changed, and the game was playable. Needless to say, there are still some graphical errors in battle, using summon, white/black magic, etc. but that didn't bother me too much.

Oh, and by the way, I played this on my outdated galaxy S2, so it should work better on more recent devices, although I have no idea how that works.

Hope this helped
