I recently tested out the Drastic Emulator demo on my Galaxy S5 with a couple ds games, including TWEWY.
Holy crap, it's ridiculously good. It's a "drastic" upgrade from the DeSmuME emulator on my Mac. Instantly bought the app so that I can properly play TWEWY and Phantom Hourglass.
So yeah, Mac's touchpad can only do so much. It didn't sit right with me that I was still E ranking battles on Day 3 in the game and that I couldn't sell pins at the shop, so ofc I'm starting all over on a much, MUCH better emulator. Never thought obtaining A rank in battles would feel THIS good. I'm still blind past Day 2, so no spoilers, plz. It's a great game so far, and I plan to finish it.
