Golden Sun Recompiled - 0.5.2

More fixes for both games and the launcher since 0.5.1.
I've also listed the sprite memory fixes that weren't explained individually
in the 0.5.1 notes.

The Broken Seal

• Seamless mode now lets you choose where to save the Clear Data, with
  confirmation before overwriting a slot. Choose another slot to keep your
  playable save; The Lost Age imports the Clear Data from your chosen slot.
• Fixed a cave flickering at the top of the world map when it should have
  been below the screen.

The Lost Age

• Added "Update from The Broken Seal" under F1 → Game. Choose a TBS save
  file, its Clear Data slot and the saved TLA slot to update before the
  reunion. Your current game stays intact, and a backup is kept. Load the
  updated slot to use the new transfer data.
• Fixed the crash when opening the world map.
• Fixed some missing scenery around Gondowan Cliffs in the wider view.
• Fixed Felix and the moving crate in Kibombo losing access to the extra
  sprite memory when their animation changed, briefly showing bits of text
  instead of their proper graphics.
• Fixed the scenery turning the wrong colours around the Djinn menu.
• Fixed extra copies of Drench appearing around the edges of the wider view.
• Fixed the water stopping short at the edge of the wider view while on
  the ship's deck.
• The Walk Speed setting now applies to sailing too.

TLA sprite memory fixes

These were already included in 0.5.1, but deserve a proper mention:

• Increased the sprite memory available for characters in the wider view,
  leaving more room for menus, portraits and effects.
• Fixed cases where running out of sprite memory caused Pound to look
  garbled, menu icons or portraits to go missing, and dialogue to become
  corrupted.
• Fixed garbled sand effects and dust puffs showing the wrong graphics.
• Fixed corrupted battle sprites caused by fighters using the extra memory
  meant for field characters.
• Fixed character graphics briefly becoming corrupted when opening or
  closing menus.

Both games

• Keyboard, controller and hotkey bindings now carry between both games.
• Added an Alternate controller binding under F1 → Controls, allowing the
  D-pad and control stick to work at the same time.
• Added Soft Reset under F1 → Hotkeys, configurable for keyboard or
  controller and unassigned by default. It restarts the current game while
  keeping disk saves; unsaved progress is lost. After a Seamless handover,
  it returns to The Lost Age's own title screen without repeating the transfer.
• Restored asynchronous GPU readback: frames are queued rather than always
  waiting for an immediate copy from the GPU to the CPU. This is intended
  to reduce CPU/GPU waiting; a speedup on slower graphics cards hasn't been
  measured yet.
• Improved how the picture updates when resizing the window or switching
  between menus, spells and the world map.

Launcher

• The game selector now shows the version number.
• ROMs can be imported regardless of their filename, but must still be
  .gba files. They're checked to make sure they're the right ROM unless
  you enable "Skip the ROM check".
• Linux's KDE file picker now has an "All files" option.

Known issues

• Loading a savestate in a larger view than it was created in can still
  cause garbled graphics across the screen.
• TLA: some map scenery outside the original view at Gondowan Cliffs still
  looks garbled.
• TLA: Raging Flood has the wrong shape, gets cut off at the edges and
  causes slowdown.
• TLA: an effect in Great Gabomba can show bits of text instead of its
  proper graphics.
• TLA: slowdown during the Great Gabomba ritual remains unresolved.
• TLA: snow scenery can appear a frame late in the wider view.
• TLA: sailing scenery remains around the edges when opening the map screen.
• TLA: occasional startup and loading pauses are still under investigation.
• TBS: rain doesn't fill the wider view during the intro.
• TBS: the scenery around Kolima's pond doesn't follow the water as it drains.
• We're still looking into performance improvements for both games,
  including Turbo speed in TLA.
• TLA: we've had one case in playtesting where the animation when getting
  a Djinn stuttered. We haven't been able to reproduce it yet.
