I get the error: "The selected game is missing one or more required ROM or CHD images. Please select a different game." for almost any romset that I try to execute with MAME.
I've searched around some and found various solutions, most of them seem to deal with having the correct BIOS for the system the ROM is for in the ROM directory, or that romsets for MAME are simply picky about the version they were dumped with.
In particular I'd like to play Metal Slug 3. I have the neogeo.zip (BIOS fileset) in my ROM directory. I have tried different dumps but I always get the same error.
I'm using Linux Mint and "Build version: 0.146 (Jul 31 2012)" of MAME.
What exactly do I need to play Metal Slug 3 (or even Metal Slug 1 or 2) with this build?
I've tried to execute mame with "mame -v" to get verbose information but I don't get any warnings or errors, so I have no information to indicate what is wrong. I tried installing "mame-tools", although I have no idea what tools are installed. Are there any tools I can use to verify that my romset has the correct checksum, or to determine what files (if any) might be missing?
