Dumping

1. Dump once (replace TITLE with disc title): redumper --verbose --refine-subchannel-rw --retries=300 --image-name=TITLE_dump1
2. If the R-W error count is high, you can perform the refine step again with higher retries (use a different redump compatible drive model if you have one): redumper refine --verbose --refine-subchannel-rw --retries=600 --image-name=TITLE_dump1
   1. Note: Assuming there were no C2 errors in the initial dump, the bin/scram file should remain unchanged (no need to redo split/hash steps), and further refine steps will only affect the subcode file
3. Create a .cdg and .sub file: redumper-extract-rw TITLE_dump1 TITLE_dump1.cdg TITLE_dump2.sub
4. Dump a second time repeating Steps #1-3, but use TITLE_dump2 instead (so you don't overwrite TITLE_dump1)
5. Compare hashes of the cdg files for both dumps, if hashes match then it should be good!
