NeoGeo games a cut off at the bottom - screen offset?

[marctv]

Hi! Thank you again for this working RetroPie alternative! Great work! Now that my 360 pads are not flashing anymore I noticed that neo geo games are cut off at the bottom. All other emulators work fullscreen with not overscan what so ever. Except N64 which is too small with big bars at the bottom and top. Any idea how to fix this? And maybe N64, too?
