build_ios.sh only wants baserom.us.z64

[Ectalite]

Describe the bug I've read the wiki on how to build sm64 for iOS on Mac and when I launch the build_ios.sh it only wants baserom.us.z64 and not my baserom.eu.z64. (See screenshot)

To Reproduce Steps to reproduce the behavior:

1. Do all step of the wiki until launching ./build_ios.sh
2. run ./build_ios.sh
3. It gives me: Failed to open baserom.us.z64! [Errno 2] No such file or directory: 'baserom.us.z64' Makefile:256: *** Failed to extract assets. Stop.

Expected behavior ./build_ios.sh should run with a EU Rom.

I built sm64ex on my pc, so I know that you can add an argument. I'm not sure what it was though...
