Hey guys, I recently made a discovery that you can allow any player to come from a custom school.
I had this question a month or two ago when making a custom high school roster, and I finally found the solution.
In order to do this, I used the 1.05 Abridgd Edit Player Table (Linked Below), and you can just edit the address name.
Go to the player you want to change and go into edit player.
Then, go onto the cheat table and go to the VITA box and check it.
Once done, scroll down to the College/From option.
You can then edit the value below it to any school name you want. This takes only a couple of seconds and there's no need for anymore modding.
(Also, to use the cheat table below you must have patch 1.05 installed)
Happy Roster Making!
