The error is fairly descriptive. You either need parent ROMs for the ROMs in question (meaning they are derivative works) or you are trying to use the wrong version.

See some of the advice in the SDLMAME thread (oldpmaguy recommends a program that can validate your ROMs), and try looking in some of the many fora that exist to discuss emulators and MAME, as this is not specific to the Maemo version and out of scope for Games here.
