+-- Memory Card Filter Override (MemCardFilter = s)
+---------------------------------------------
+-- By default, the FolderMemoryCard filters save games based on the
+-- game's serial, which means that only saves whose folder names contain
+-- the game's serial are loaded. This works fine for the vast majority
+-- of games, but fails in some cases, for which this override is for.
+-- Examples include multi-disc games, where later games often reuse the
+-- serial of the previous disc(s), and games that allow transfer of save
+-- data between different games, such as importing data from a prequel.
+-- To allow multiple serials separate them with slashes, like this:
+-- MemCardFilter = SLUS-12345/SLUS-12346/SLUS-12347
