 If rom-path is blank (just a newline), RetroArch will attempt to load the core without a game.
 
 #### Old format consideration
-The old format for history was rom-path1;libretro-core-path1;core-name1.
+The old format for history was `rom-path1;libretro-core-path1;core-name1`.
 However, this was found to be a bad idea as ';' is a valid path name.
 The behavior was fixed, and RetroArch used a new default path for history files (`.retroarch-game-history.txt` instead of `.retroarch-history.txt`). To convert to the new format, just rename the old history file, and replace ';' with newlines directly.
