Changing settings won't help with TMS#FE, Wonderful 101, or Fatal Frame 5. Those games are all just plain unplayable in CEMU.
Since CEMU is largely useless to me, I'm debating buying one of those Wii U refurbs that Spronk linked a couple pages back. I really only want it for the 3 games above, plus Bayonetta 2, XCX, and the upcoming Zelda. Not to derail the thread too much, but anyone able to quickly tell me what else if anything I'd need? I'll Gamefly all of them except for Fatal Frame (no physical release in NA) and hopefully I won't need to bother with an external HD, but do any of them warrant using a pro controller instead of the gamepad? I'd probably mod it for homebrew so that I can play uncensored TMS#FE too. Not sure if having to play from a dumped image affects the amount of storage space required for games. On the plus side it sounds like you can pretty easily use a DS4 instead of a pro controller on a hacked console, as long as you don't mind it being wired.
