Problem getting NES to work with GameEx using MAME

[John Simon]

 

I may have posted the problem a long while back, but I could not find anything.  I apologize if I did and did not see it.

I am trying to get NES to work using MAME0262b.  When I use the default command line in the setup, I get the following error.

-------------------------------------------------------------
mame.exe nes -cart "D:\PT Torrents\ROMS in Use\MAME\nes\1943.zip" -joy -now

Fatal error: Device NES Cartridge Slot load failed: File is not an iNES or UNIF cartridge image

-------------------------------------------------------------

The rom files are zipfiles I downloaded and contain several files that end in chr and prg.  I was not familiar with the specific image formats referenced.

I did find the following command line works outside of GameEx.

             mame nes 1943 -rompath "D:\PT Torrents\ROMS in Use\MAME\nes" -joystick -nowindow -skip_gameinfo -output windows

So, I tried specifying this command line in GameEx:

             mame nes [ROMNAME] -rompath "[PATH_ROMS]" -joystick -nowindow -skip_gameinfo -output windows

but this command doesn't work in GameEx because passes "1943.zip" as [ROMNAME]  instead of just "1943" and I get this error.

-------------------------------------------------------------

"1943.zip" approximately matches the following
supported software items (best match first):

* Software list "nes" (Nintendo Entertainment System cartridges) matches:
1943              1943 - The Battle of Midway (USA)
1943jp            1943 - The Battle of Midway (Japan, prototype)
1943j             1943 - The Battle of Valhalla (Japan)
1942              1942 (Japan, USA)
1944              1944 (1943 pirate)-------------------------------------------------------------

Any thoughts on how to get GameEx to omit the ".zip" when it passes the argument to MAME?

====================

I also tried Retroarch, but it doesn't like zip files and get this error.

-------------------------------------------------------------

[INFO] [Content]: Core requires uncompressed content - extracting archive to temporary directory.
[ERROR] [Content]: Failed to extract content from compressed file: "D:\PT Torrents\MAME 0.262 Software List ROMs (merged)\nes\1943.zip".

-------------------------------------------------------------

I thought this might be a permissions problem with it trying to extract to a location that needs elevated privileges, so I changed the temp directory in Retroarch to something other than \users\xxx, but I am still having this problem which is why I was trying MAME.

 

Any thoughts would be appreciated.

Thanks,

-John

Hi John - sorry for the late response.
