Emulator wont play games from mamewha

Hi guys first post but wont be the last and i hope its in the right section

my problem is (after i have configured mamewha etc) that when i select a game from mamewha it takes me to the emulator game list instead of booting the game.

im using mameui32 and iv also tried it with mame but still the same thing.

is there a particular emu i should be using with mamewha? have i missed anything with the ini file. does the emu need to be configured,???? mmmmm

im out of ideas on this one, im thinking i should just have the system boot straight to mame

any info would be great

cheers
