Good news: I have it running now! Also added an archive of some required toolchain libraries; just copy those over and you shouldn't need to compile any.
opk here

Complains about system entries, buy I'll let you handle that.
Ran a test, but there's no way to get past the config error. Paths are correct as far as I know. I suggest we add a pre-configured file, which is why I'm gathering GCW-Zero emulators. Looking into it now.
I also noticed ES is under emulators. We'll need to move it to applications. The aim of the program is so one may delete the emulators section on the home screen and still access their games. It saves space.

Update: I now have a working config thanks to Aloshi. Ran the test for fceux, but after selecting a game, the screen fades out and back in. It may not recognize .opk. We may need to add that.
For those of you who want to check out the progress so far, keep these issues in mind:
ES is under the emulators section. We'll move it to applications.
1. Scraper doesn't work. (We have yet to implement this.)
2. Sound settings does nothing. (We need to program it to change the Zero's volume, or remove it.) If anyone knows how we can accomplish this one, let us know. I haven't seen it used in an app on the GCW-Zero.
3. Emulators don't load. Choosing a game does nothing. (This is because the emulators terminate themselves after ES loads them.)
4. Restart System and Shutdown System in QUIT do nothing. We'll likely remove these.
