Mame.exe can't launch certain ROMs outside Mame32
(1/2) > >>
jlfreund:
I'm having problems running a few ROM's outside Mame32.  From Mame32, all my ROMs launch just fine.

But if I try mame.exe from the command line, or preferrably, launching from MameWah, about 10% of my ROM's don't launch, giving a file not found error.

For example, asteroid1 complains 136002-125.d7 not found.  I checked and none of my asteroi*.zip archives have that file in them, however it evidently isn't a problem when launching from Mame32.  Other games that give similar errors are Millipede and Tempest, though Asteroids Deluxe, and Centipede both work fine.

I am pretty sure all the paths are configured correctly.  In MameWah, it can find 90% of the games, and when running mame.exe from the cmd line, it seems to find the zip files, it just complains about a missing piece inside the zip.

Could it be there is some meta file (like an xml or dat file) that is correct for just Mame32, but either not found or out of sync for MameWah?

Are you certain you are running the same exact version of Mame as compared to Mame32 ? The roms have to match the version of Mame\Mame32.

I would verify your version of Mame command line, and check your Roms with a rom manager, like Clrmamepro...

My mame command line is 109b, and the roms came from a 108 set.  The mame32 is 106. 

Do roms change from one Mame release to the next?  In Maws, it says there was a change to asteroid in 108u5, but I don't see how that could be related to a file not found error.

Havok:
Unfortunately, they do change. Grab the 108 version of Mame, and it should work fine. You can get it here:

The 109 version you are running is expecting that change, and the Roms you have don't have it.
jlfreund:
Thanks -- I'll try that out.  BTW, what's a reason that a ROM could change from one Mame release to the next?  I would have assumed that once a set exists, any improvements to the emulation would be in code, not in the ROM?
