v1.1.0

Updated game_screen backgrounds for snes9x_3ds emulator v1.61+.

• Game-screen backgrounds are now optimized for the new 448x256 target size,
  which avoids exposed edges at higher 3D depth settings.
• Updated some gameplay thumbnails. In thumbnails.zip, only gameplay.cache changed.
• All other asset packs are unchanged from v1.0.0.

Setup instructions are documented in README.md.
You can track covered games in the src folder via file lists and preview assets.
