MAME runs the game more gets black screen and only hear the sound

[geannf]

Some games MAME function normally, others are getting black screen and only hear the sound, I can put the credits and start the game. Summarizing the game runs so that nothing appears on the screen, what can this be? Thanks for any light, already tried everything, I do not know what else to do.

My video card is a Geforce GTX 660.

The version I tested the mame are the 0150 and 0154, and none of them worked, always getting black screen.

I appreciate any help

Are the game that are not displaying vertical games (Donkey Kong, Pac Man, Shmups, etc.)? I have seen in the past with these vertical games where if you do not set MAME to maintain the aspect ratio, the games are displayed off center or offscreen. See if you can set the 'Keep Aspect' (or something similiar in the mame.ini file) to '1' for yes. Not sure what the name of the setting is, but if you Ctrl+F in the mame.ini for 'aspect' it should be the only setting there with this value. Keep in mind, you may not have mame.ini file in your mame directory, you will have to generate it with this command from a DOS prompt:

mame.exe -cc

You may also have bezels enabled and if there is no artwork in the artwork folder you can get a black screen. That can be changed in the video options by pressing "Tab" Or turning bezels off in the mame.ini.
