+Lock-On Support
+---------------
+
+This version of BlastEm has some preliminary support for Sonic & Knuckles lock
+on technology. This is only available from the command line at the moment. To
+use it specify the Sonic & Knuckles ROM as the primary ROM and specify the ROM
+to be locked on using the -o option. As an example:
+
+	./blastem ~/romz/sonic_and_knuckles.bin -o ~/romz/sonic3.bin
+	
+Please note that Sonic 2 lock-on does not work at this time. Additionally the
+save RAM added by Sonic 3 won't work either.

 vsync, please see the VSync section at the bottom of the README.
 
+"fullscreen" controls whether BlastEm starts in fullscreen or windowed mode.
+This can be overridden on the command line with the -f flag. If fullscreen
+is set to "off", -f will turn it on. Conversely, if fullscreen is set to "on"
+in the config, -f will turn it off.
