 just point visual studio at the CMakeLists.txt, apparently that's a thing it supports now.
 
 make sure you provide the gbcamera rom as `argv[1]`.
+
+### for everyone again
+when running, the inputs are
+- arrow keys = dpad
+- z = a
+- x = b
+- enter = start
+- backspace = select
+
+in gbcamera, you can use backspace to open the settings for dither, flip, palette, etc..
+
+(you can technically back out of the camera mode and access the rest of the gbcamera minigame stuff, but it'll be running unplayably fast since we try to run the emulated gb's much faster than realtime to keep up a decent framerate)
