I finally 1-credited R-Type Delta on Normal. I used the RX. My score was 795,xxx. I died once--of all things, a Pata-pata shot me near the end of stage 6.

It would have been nice to break the 800,000 point barrier, but I would have had to die on purpose, which wasn't a risk I was willing to take.

I'm still not done messing around with Normal. I want to try and 1-cred with the R-13. Then I'll try to get the last 3 backgrounds I'm missing from beating Hard with the 3 main ships.
