Hey guys, I recently updated from an older Mame (.94?) to .100 and I'm having these 2 problems. I've tried a few things to figure this out but I'm not getting anywhere. 
1. In Mamewah 1.61, I can't generate my main games list with ALL available games. Which listgen method should I be using to generate a list of all games? Whatever was the default worked with my older version but not the new one. 
2. In Mame, in the Tab menu, I no longer see a Game History option. I have history.dat in my Mame folder. 
Any help with these two issues appreciated. 
I mainly upgraded for the Robotron issue and I love the new version! 
Thanks.
