Thanks drboom, but I'm not done yet! My first credit of the day gave this:
NORMAL MODE - IKUO
178,420,340 - EOJ - 1-ALL
Close to a perfect run with my current strats. I beat the crap out of stage 5 in this one, going into the last boss with 5 spare lives. Never lost my medal chain throughout the run. Only thing I fudged was the last phase of the last boss. I used a bomb instead of my lard attack at the very end, killing it, and costing me 2-3 mil. Would have been just enough to push me over 180mil.

But I'm pretty happy with this score, especially since it's also a 1CC.
