Need help getting Mupen64 working

Just posting the solution to the problem here … again, to resolve and hopefully mark this as solved. It was cross posted across a few threads.
In a nutshell: incomplete download problems.

This thread is a duplicate/continuation of this one:

Getting back onto mupen core problems. Like I mentioned in another thread, you need to be patient. Just on the mupen core compilation, it can take 10-15 minutes. This is compiling. There is no verbose feedback. You just need to wait it out. Same thing applies to download. You gotta be patient. Perhaps don’t download more than one thing. Consider purchasing a network cable, and connecting to your router directly. This is for your computer laptop, since you appear to be having problems just downloading the image.

I don’t recommend you use the DEOT v2.0+ 0.5. It is in its early days. I will be posting hot fixes, updates, and version revisions. This will require lots of redownloading. You will be going back and forwards with questions.
