EmulationActivity has an instance of Settings. If you go to
SettingsActivity from EmulationActivity and change some settings,
the changes get saved to disk, but EmulationActivity's Settings
instance still contains the old settings in its map of all
settings (assuming the EmulationActivity was not killed by the
system to save memory). Then, once you're done playing your
game and exit EmulationActivity, EmulationActivity calls
Settings.saveSettings. This call to saveSettings first overwrites
the entire INI file with its map of all settings (which is
outdated) in order to save any legacy settings that have changed
(which they haven't, since the GUI doesn't let you change legacy
settings while a game is running). Then, it asks the new config
system to write the most up-to-date values available for non-legacy
settings, which should make all the settings be up-to-date again.
The problem here is that the new config system would skip writing
to disk if no settings changes had been made since the last time
we asked it to write to disk (i.e. since SettingsActivity exited).
NB: Calling Settings.loadSettings in EmulationActivity.onResume
is not a working solution. I assume this is because
SettingsActivity saves its settings in onStop and not onPause.
Added Opacity controls for the user to customize the opacity of their touchscreen controls. Also, placed both Scale and Opacity settings into one window/option called Adjust Controls.
In 8c723d0, I intended to update the main activity, emulation
activity and game properties dialog, but I forgot to actually
update the game properties dialog. This commit fixes that.
The changes outside of GamePropertiesDialog.java are just
to hide the Wii controller settings for GameCube games.
Basically, instead of having one button for config, one button
for graphics settings and so on, we now have just one settings
button which takes you to a screen where you pick between
config/graphics/GameCube controllers/Wii Remotes.
The main reason I want to do this is because people still have
trouble finding Overlay Controls in the "new" in-game menu.
Typically (depending on the screen size and the length of the
game name), the scrollable part of the menu can fit 4 items,
and merging Config and Graphics Settings into one item would
move Overlay Controls from 5th place to 4th place (assuming the
user doesn't have savestates enabled), which makes it findable
even for users who don't realize the menu can be scrolled.
The dialog that's shown when long pressing a game in the game
list is also shortened. While not a pressing matter, I think
it was getting a bit long.
An additional reason to do this is because we probably will
want to make it possible to edit the controller settings
from the in-game menu at some point in the future. With the
old approach, this would require us to dedicate a whopping 4
menu items just for settings (not including Overlay Controls),
which I think is excessive.
I moved it from the main settings screen to the in-game menu
in PR 8439 so that it could be changed while a game is running,
but now that the main settings can be accessed while a game is
running, there's no reason to not put it in the main settings.
