Hi
I'm writing a frontend, and am in the process of reading in all the mame data so I can store it in my frontend.  So far I've read in and parsed mame's -listxml output, and I have catver.ini and history.dat to read in next.
Are there any other files such as catver.ini and history.dat that  I should be aware of and read into my frontend, to help the user experience?
Many thanks
Jimbo
