After what i understand you can replay remind, limit and secret episode again with all codes turned on to get 365000 points and an A rank. (But guess this will be quite a challenge). If you run through the main game again (for a easier time i would recommend beginner) with all codes turned on for the bosses, you will get 165000 points, with additional 10000 by defeating the final boss in remind. Then you are left with 190000 to get from the limit bosses, with the opportunity to have some of the codes off to make these fights a bit easier. Still grinding through main game for the nth time, so can't confirm this 100% yet though.
