NESC: FB Neo can't load any games except for Neo Geo CD

After the last thread, I found that FB Neo has Colecovision, but it won’t load ANY games. Here are the consoles that will NOT load games…

-Colecovision -MSX1 -PC Engine -SuperGrafX -TurboGrafX 16 -Sega Game Gear -Sega Master System -Sega SG1000 -ZX Spectrum

I have the corresponding bios in the system folder. But the only console that works on FBNeo is Neo Geo CD.

What is going on? How can I get it to work?

Again, this is running on an NES Classic Mini. The version(at this time) of Retroarch is 1.7.7. And I have no clue what I am doing wrong or why none of the consoles via FB Neo aren’t working. I need help.
