i also have got same problem.....
but u can be one step forward to make a DAT file......
this file contains all the information of the mame.exe
supporting games,rom information etc.
u can make ur own dat file in simple steps.....
1)go to the dos promt .
2)c:/dmame -xml2info >dmame.dat
.......ok......
Tried that and when I tried /dmame it said that it was not recognized as an internal or external, operable program or batch file.
And when I tried it with just mame (no 'd's' in front) it said "Error: Unkown option -xml2info
Error while parsing cmdline"
Can you paste up your EMU1 CFG File from Mamewah / Files / EMU1 .. maybe theres something in there we can pick out? I say this as I had exactly the same problem .. and I can't for the life of me remember what it was, but I'd like to try and help
I'm sure it was just a setting that was out ... nothing too complicated.
Okay...I don't exactly get what you mean by this. Do you want me to just post what the names of the CFG files there are in that folder, or is there a way I open them up and post what's inside of them by notepad or something? I'm good at overcomplicating things

And just so you know, mame.exe is in my C:\ folder (so it's C:\Mame.exe) and my roms are in C:\roms.
