You may want to start with the list in
this thread.
It has a variety of good titles, even if some of them are older than what you're looking for.
and also with that sort of games you have an emulator ? i can get from somewhere ? or i should download the games one by one ?
Please observe
Rule 5 -- Don't ask about where to download ROMs/ROMsets.

That said, it's easier to download an entire ROMset and use a compatible version of MAME than it is to download one game at a time.
Consider using MAMEUIFX (a GUI build of MAME) for making a gamelist.
I keep an "archive" folder with a full ROMset under the "roms" folder.
When I want to add/remove games I just copy the desired file into (or delete the existing copy from) the "roms" folder.
This is a great way to build and refine a list of games that you like.
Once you have the desired games, install MAME (official build version for greater stability) and the desired front end on your cab.
Copy all the related ROMs to the MAME "roms" folder on your cab and configure MAME and your front end.
