Showing subversions / duplicates with MAME

[linux4eva]

I have Attract mode configure for use with MAME. The ROMs are .7z and the front end doesn't see the subversions which mostly is a good thing, but what should I do to be able to launch Ultimate Mortal Kombat 3 which is located in mk3.7z archive?

Thanks!

You will have to provide some more detail and explanation. By subversions do you mean clones? Do you have a MAME merged set? What happens when you try launching mk3 through MAME, vs through attractmode?

The more detail the better.

7-zip? (.7z) normally mame roms are zipped (.zip) We do need more info to help you though.

Why not just un7zip the file, then recompress it as a .zip?

Also without using attractmode launch the rom with mame and post the output

Code: [Select]

c:\mame_folder>mame.exe romname -v >romname.txt
I'm going to make assumptions.

Your /romlists/mame.txt does contain

Code: [Select]

#Name;Title;Emulator;CloneOf;Year;Manufacturer;Category;Players;Rotation;Control;Status;DisplayCount;DisplayType;AltRomname;AltTitle;Extra
umk3r10;Ultimate Mortal Kombat 3 (rev 1.0);mame;umk3;1994;Midway;Fighter / Versus;8P alt / 2P sim;0;joystick (8-way);good;1;raster;umk3;;

Your umk3.7z file does contain all the .bin files. Double click on umk3.7z to check that. I'm assuming your umk3.7z doesn't have a .zip file located in it.

Your /attracemode/emulators/mame.cfg file contains

Code: [Select]

romext               .zip;.7z;<DIR>
Your mame.ini file has your rom path set.

Code: [Select]

rompath                   /mame/roms
