Rom sets for WinKawaks and MAME are quite different from NeorageX sets...
Open the zip...if the files inside have file extentions of *.ROM then you have a Neorage version. If they say *.BIN then you have a MAME / KAWAKS version.
Also keep in mind that in MAME the zip file must contain the neo geo BIOS inside.....simply borrow it from neorageX
