Emulator Questions

I have found many sites that allow playing of CLASSIC ARCADE GAMES using Java emulators (Cottage,Jemu,etc) and these games DO NOT HAVE SOUND!! (Most of them)

Is this due to the EMU not be compatible with said games or the person who uploaded it not doing something right?

Heres one that has NO SOUND

Its quite sad to have said games available but NO SOUND!!

I have heard alot about MAME,do these games have sound using MAME?? (I have heard thats a good emulator)

The site that links to is in breach of the forum rules. Better to take it down. Regarding your arcade gaming needs, just use Mame. It plays almost every arcade game from the 80's and early 90's pretty much faultlessly.
