Omega

[sword]

I'm having trouble with Omega.  It wouldn't et me convert a BMP into a TEX. The button won't highlight.
I'm trying to swap out Aeris's portait for another thing. I checked and it's the same size as the other.

I'd suggest you to try LGPTools. Simply right-click on the TEX file you want to change and select Replace. Then simply select the BMP you want o use.
By the way, Omega doesn't work for me either, it just causes a general protection fault.
