MCC-216 Rom Help

[mtshark7]

So I got one of those MCC-216 consoles.

 

I know how to update the cores:

But can't seem to get to add roms correctly to C64, Atari 800, Atari 2600, & ZX Spectrum.

 

I saw this youtube video of how to update the C64 roms but that seems like too much of a hastle:

 

I read the manual and that doesn't explain much either.

 

Does anyone know an easy way to update the roms on this thing?

 

Thanks!
