The only information I could find on this was this post:
http://www.libretro.com/index.php/mamemessume-cores/
Which core is this? Aracde (MAME) or MULTI (UME 2014)? In the current MAME, MESS was unified and there is no separate MESS/UME anymore.
Can someone walk me through this?
If I want to use a game with samples (such as Q*Bert), I put the samples in what directory? (relative to the location of qbert.zip)
If I want to use a game in MESS, (such as circus.zip for a2600.zip software list, I need to put
a2600.zip in what directory?
circus.zip in what directory?
I also need the hash file a2600.xml? Where does that go? Should it be zipped?
When I choose “Load Content”, which file do I pick? a2600.zip? circus.zip?
