Different versions of games

Why are there lots of the same games in the arcade, the only difference I can see is one is for V32 or there is a yellow dot next to some and not the rest?

Take Coffee Rush; there is Coffee Rush, Coffee Rush v2 and Coffee Rush v32. Are they the same game?

Thanks

I could have the same game install but from different games converters..

Then you have different game versions.. v2,v3 and v32..
Only difference is cheating protection.

Is there a safer version to play then? I was starting to think it was more to do with updates of the same game, like patches and fixes to improve the original release.

Their all about the same.
If someone wants to cheat. you can with any version.
