Here's a little script I made that others might like. If you don't like the script, then you might like the custom .ini and .lst files that come with it From the readme.txt:
List Creator v0.1
Here is a script that I created that takes the XML from Mame and the Catver.ini and creates a Custom list for each category that is in the Catver.ini. This is set up so that you should be able to run this anytime a new version of Mame comes out. If your Catver.ini is older than your copy of Mame, it will put those games not found in a separate custom list called "No Category". Also, all Mature Games are filtered out into the Mature Custom List before anything else is filtered. Here's how to run it:
1) Install PHP from
http://www.php.net (PHP has a command line interface, so you don't need to have anything else running);
2) Add c:\php to your path (path=%path%;c:\php;);
3) Run "mame -listxml > list.xml";
4) Put both list.xml and Catver.ini in the same directory as listcreator.php
5) Run "php listcreator.php";
6) Copy the files over your Mamewah install.
Enjoy!
Any problems, please email me at keeftm@hotmail.com with "List Creator" in the title, or else I might miss it. Thanks!
If you have any questions, let me know.
(oh, and delete the .txt extension from the download)
