how to create a game list with 2 MAMES?
I have 2 Mames. Mame 0125 and 0157.
I would like to create a single list for 2 mames.

you might want to look at the sticky topics in this sub-forum.  It's covered there.
Basically you change mala calling MAME.EXE to MAME.BAT and then branch off the rom name to whichever version of MAME you want to use with that game.

I tried but I could not do.

You could have two differents emulators in MALA with different lists or you can use an unique list using this (see attached photo).

Perhaps, the problem if you use only one list is that you could have a problem because each mame must use differents roms.

I could not. I did like the picture.

using this method, do I need to use a bat or cmd file ?

You don't need use bat files.

Please, can you put screenshot of your Mala setup?
