Questions about the emulation on these games

[INNUENDO]

Hello, guys. Some simple questions about these games, ok?

MORTAL KOMBAT 2 - I don´t know yours, but in my computer the SOUND IS VERY LOW! I need to put on the maximum volume to listen it. Has some option to make the sound more higher?

What means THIS GAME LACKS SOUND on FIRE SHARK??

Why some games like DODONPACH and GRID SEEKER are UPSIDE DOWN sometimes?? When I play on MAME 60, this happens....

This is all. If you can help me, thanks.

You have to enter into service mode and increase the volume of the sound manually,this every time that you play that game(it's saved by nvram and nvram aren't allowed,you know).Midway/Williams loves to have a very low default sound volume in their games...

What means THIS GAME LACKS SOUND on FIRE SHARK??

"Maybe" because that game doesn't have sound???

Why some games like DODONPACH and GRID SEEKER are UPSIDE DOWN sometimes?? When I play on MAME 60, this happens....

Again,enter into service mode and change the flip settings to "inverse","flip" or whatever different to the default one...
