How were you able to work out that 2031 was Parker's corresponding APPEARID? I'd like to know so I can work out how to get the other missing players fixed as well.
I just looked at the players.dbf and you'll see that james singleton is PLAYERID=2030 and than you have smush parker and pat burke at 1073 and 1072, respectively. The next PLAYERID is 2033 for Rawle Marshall, so i just assumed that smush's APPEARID would correspond with 2031. Before I edited it, I made sure that the height, weight, and color actually fit smush parker (which it does). If you look at the next APPEARID (2032) it looks like it matches Pat Burke (based on the height (6-11), weight (250),and color (0)), which makes sense since in the players.dbf pat burke was right below smush parker.
Now I haven't gone through to see if this is right for everyone else below these guys but it worked for smush parker (I haven't gotten a cyberface and portrait for Burke yet).
Hope that made sense.
