Well.... I'm still learning about Mame and MameWah and Mame32 etc. etc. So I still class myself as a nOOb when it comes to stuff like this. But I always thought that Mame32 was a frontend in itself...... sort of a standalone program on its own. Great for first time users who just wanna get straight into some retro action using a familiar Windows style interface.
But MameWah is (as far as I can see) specially written for cabinets in mind.... of for people who don't want a Windows style interface. Horses for courses I suppose.
Unless of course I have the wrong end of the stick....
