Creating Custom Team, Players etc. problems

Why does my NBA crash whenever i make my custom team with custom players.

I edit the Teams.dbf, Teamgear.dbf, and the location.dbf because i'm also creating my own art(court)

When creating court, first i need to have a viv file for my court or i can make not in viv format?

And here's another problem whenever i choose my custom team my NBA turns black the background and the video all turns black so i need to restart my NBA After i restart my NBA it still happens. WHY IS THAT?

And when i create my own jersey it doesn't show in the select jersey menu.WHY IS THAT?

Can someone help me with my big problem...


THANK YOU.....

I'd say you've made a mistake somewhere. Which tutorial have you been following? You might have missed a step or entered an incorrect value somewhere along the way.

THE NLSC tutorial

If you're specifying a custom team abbreviation (which you need to do if you're creating your own art), I'd say you've got missing art which is causing the game to crash.

Ahh okey... a court should have 12 files right? I think.. i will check it.

How can i create an .O file? what software should i use?
