Odyssey2 games not loading MAME

[TopGunBass]

Hi guys, I'm trying to use mame to load odyssey2 games.
Emulator is set as MESS
Assosiated platforms: magnavox odyssey2
Default command: odyssey2 -cart
I have odyssey2.zip in mame rom folder.
Odyssey2 games are .bin
After importing Roms when I launch a game it trys to load and then a black screen then back to launchbox menu.  Is there something I'm missing.  Can someone help me out.  Thanks.

Try using just "odyssey2".  Or if you must, "odyssey2 -cart1".

You also need "i8244.zip" (device file) and "videopac.zip" (parent rom)

For MAME (and even [old school] MESS), the files need to be zipped.

For example: "A Labyrinth Game / Supermind (Europe)", MAME is looking for "2lbsprmd.zip".

Also, make sure Extract ROM archive before running is NOT checked.

Thanks Joe.  When I added the i8244.zip and videopac.zip the games were able to launch.  No other set up in launch box was needed.  Oddly there are no functions for mame to configure anything.

What are you needing to configure?

Well once a game launches no way to exit back to menu.  Tab key to config controls doesnt work. Strange.

Press your ScrollLock key 1st. Then you can press Tab.

Scroll lock key did it.  Thanks
