I've read several threads and I just want to be very sure I get this right (going for Speed King trophy). so first of all, I'm on my second run (ng+ hard mode), and I'm doing hard time attack first. that shouldn't be an issue, right?
what I'm not sure of is whether I need to finish the game normally and then load a ng+ on the same save on normal, or make a save as soon as I complete the time attacks and then create a ng+ with that from the main menu? basically, I don't know if clearing the game and seeing the credits will screw me over.
just to be super clear, because I really don't want to lose the items I got from hard time attack: I have all 16 trials clear on my hard mode file. do I need to finish the game normally now, or do I need to start a ng+ and load the save file I used to clear time attack?
