Ratchet and Clank 2: All 100 Desert Crystals in one run

Just wanted to try this. It's not too hard, just time consuming. Though this was challenge mode. Which mostly means I can abuse the Shield Charger. And the RYNO 2. Also note that Crystals aren't worth as much on normal. (only 1000 each) There are exactly 100 crystals total, but you use the first 10 for a plot-relevent sidequest, so you only get to sell 90. So that makes 900,000 total profit for challenge mode and 90,000 for normal.
