On xbox360 for NBA2k13... how did RayRay edit courts on his Super80 Roster?

[mo2thewillyo]

How did RayRay for his Super80 roster in NBA2K13 hex edit/redit the courts for his Super80 Roster? I noticed the baseline out of bounds the words Indiana Pacers showing up on a custom court for the 00 Pacers. Then I saw for the 04 Grizzles he had the entire paint one solid color while the out of bounds area surrounding the court was a different color. This is totally different from the custom courts normal style. How did he make this happen??? Also, how did hokup guy for NBA 2K14 (again he did it for 360) in NBA 2K14 edit the Cavs court, make a red Pelicans Jersey,and create a charlotte hornets jersey?

Yes this was all done on XBOX360. Although it doesn't compare to PC editing, its still awesome to see such manipulation. i messaged both of them but so far no answer.

Any further explanation/guidance on how to edit courts doing these things for nba 2k13 would be appreciated!
