TWL CPU speed is set in TWLMenu++ settings (not the game's settings), correct?I'm playing Pokémon White to test it, and I think it was being affected by it earlier. Scrolling through menus in particular was a lot faster. Unless I'm remembering it incorrectly, it seemed to be working when I tried it on my DSi, which I was only using to test Unlaunch before installing it on the larger model.
Edit: The DSi XL is on version 1.4U, could that affect anything?
Edit 2: Actually, I think I am misremembering. I've only been able to get it to work while playing it through the SD card from a normal 3DS. The flashcard isn't working there, either. I guess I'm doing something wrong somewhere.
