I ran a test from Hyperspin... If I choose Mame as the emulator the games run full screen

If I choose Groovymame they are all messed up unless the game is running at 640x480 such as Blitz2k although the game is running half speed which is an issue to address later

So I must not have something right in groovy....suggestions?
Attached are two game examples and one of desktop working correctly
