Don't ask for roms here... its against the rules and will otherwise just stir up controversy.
You might want to run your roms through ClrMamePro to verify that they will work with Mame .97. You can find a tutorial on it at
http://www.mameworld.net/easyemu At least then you'll know that your roms SHOULD work with your mame version.
Also, you need to get one thing straight in your mind that I'm not quite sure you are grasping. Mamewah has absolutely nothing to do with how your games run... it's just a pretty way to load them up. It doesn't matter what version of Mamewah you use, and there is no way that just changing somethign in Mamewah will stop games from working (unless of course you are altering something that affects teh actual mame.exe file.
Basically, you have to be sure that you have Mame up and running correctly before you even worry about Mamewah. If you don't have the games running correctly through Mame itself, you will never ever get it to work through Mamewah. If you can get the games working in Mame32, you shoudl be able to get them running in Mamewah. Even better, try a few games in Mame by using the command line (its very simple if you are new at it, don't be afraid). Once you know a few are working correctly, you can tackle mamewah without much trouble.
