Core info for retroarch

[Disney Rob]

I currently have 96 systems in it.
90 run perfectly....
Having trouble with   
Coleco+4
Coleco Adam
Apple II GS
Commodore Pet
Sharp X-1
Camputers Lynx
I can get these to run off desktop, or straight through Retoarch or Mame, but cannot get them to
interface with mGalaxy

Lol, you are terrific, I can't imagine your collection.

You realy use system I don't know at all.

Has anybody been able to get these systems working in mGalaxy

via Retroarch
Commodore Pet
Commodore Plus-4
They work from my desktop, but when I add them to mGalaxy they do not come up.
I added the proper core to the emulator file, that I use to bring them up in retroarch, but when I go to play them through mGalaxy it just crashes
back to  desktop.

Also and this is generic. But maybe someone can help.
I am trying to play Appleiigs, and coleco Adam through Mame via MGalaxy, but it is not finding the files. I can not even get Mame to recognize these systems,
even though the Roms are in the Mame Rom files. Any help would be greatly appreciated.
