Serious confusion about custom court\uniform graphics

[ricofoley]

Forgive me if this is answered in one of the sticky threads but, hear me out here:

I'm attempting to make custom courts and uniforms in NBA 2003 via the EA graphics editor. I understand about adding the "custom art 1" line and about using folders to overwrite the default files in the .viv files. The one thing I can't figure out is how to create\edit the FSH files that are separated into a lot of different pictures. For example, each team's court FSH file has pictures labeled "odrn, olin, olio, olip..." and nearest I can tell EA Graphics Editor will only let me save one "piece" for each FSH. Any help you can give me will be appreciated.

Also, when you have the option to put on compression when saving FSH files does it matter what compression you have on?

Thanks in advance.
