I have added all the PS2 Internal Serial prefixes currently in redump.org according to their region.
I have also added two regions: Korea and China. China because they have a different region lockout (NTSC-C), and Korea as SCEI did not allocate their serials (SCEK did). However, I have put Asian serial prefixes (SLAJ/SCAJ) under Japan as they were allocated by SCEI. If you would prefer Korea/China be under Japan or if you would prefer Asia to be its own region, I can change it.
Also, I have removed the following serial prefixes that do not exist as PS2 internal serials on redump, only as PSX serials:
ESPM, PEPX, LSP, DTL, SLUSP, SCZS, SIPS
If you know of a disc that has one of these as internal serial that I am not aware of, I will add it back.
Finally, PEPX and PUPX were the wrong way around in PSX region detection.
