advancemame, linux y juegos horizontales

Bien, tras darme la cabeza un larrrggoo rato consegui hacer andar advmenu y advmame en ubuntu 8.04 con framebuffer (y tambien con X11, pero framebuffer consume menos)

Mi problema ahora es el siguiente. para los juegos verticales (lease 1942 que tiene una resolucion 224x256) funciona de mil maravillas.
Pero para juegos horizontales (1944 resolucion 384x224) veo la pantalla negra y 3 lineas blancas gruesas

Asumo que es un problema con algo del advmame.rc, asi que lo adjunto
