Installing Stadium Select Screens

[sdoyle7798]

So I wanted to change the Astrodome to Ebbets Field. No problem there. But then I wanted to change the stadium select screen. So I made one (I made it 1330x320). Following the instructions I found here, I tried to enter it into the game (I resized to 512x512, since that was the size the astr.fsh index file showed). However it crashed when I tried to select the stadium.

Is it possibly because I am trying to place an open air stadium over a dome? Or did I do something wrong?

BTW here is the screen I made...

EDIT: This is obviously modeled after the 08 mod select screens. In fact, the dimensions field is a modified version of the Angels' dimension field found in the Angels Selection screen, made by The Big O. If this were something I would release, I would obviously get permissions, or change the field.
