Well I have all the software needed to do this now I need the how.
This is an old and round-about method of doing this, but anyhow...
1. In Windows open the Command Prompt.
2. Go to your Mame folder
3. Generate your listinfo.xml by typing
mame -listxml > listinfo.xml4. Convert the xml to the old listinfo format by typing
xml2info < listinfo.xml > listinfo.dat5. Run SortInfo and go
File>Import>Mame Listinfo File, import the listinfo.dat file you just generated.
6. Give it a minute and it will show you all the info from the listinfo file.
7. Go
File>Expot>Comma Seperated Value File and save it somewhere
8. Open the CSV file in Excel and sort it to whatever games you want.
9. Once you've got a list of the games you want, select all the rom names and copy them into a text editor (I like to use CrimsonEditor).
10. Edit it to look like the text file I attached to the above post and save it as a BAT file.
