Can anyone help me to find this emus? (If exist)

I dont know if they exist actually...
I know there is a neo geo cd emu... and actually, i play it... but i dont know how to play the arcade neo geo... the one that u can play metal slug 3,4,5..... Does exist any emu that does so?

Another question about emus is: I want to play games like cadillac's and dinosaurs and captain commando.... what emu can let me play this kind of games?

Thanks for all the help u can provide me ;)

Don't know if this helps or not...

this one supports the arcade romsets.

captain commando work well with the latest version of mame4all...pretty nice game :)

Yes, i found it!!! i tryed 4 games_

1942 (dont know if is this name exactly)
Captain commando (Working fine)
Cadillacs and dinosaurs (Works without sound!)
The punisher (Works without sound!)

Does anybody know why some games works without sound?. I hope it is not because of my roms.... :confused:
