v1.61

Features

• Added 3D depth strength setting and refined splash/background depth effects (#65)
  • Custom game-screen backgrounds are now ideally 448x256 instead of 400x240;
    400x240 images can expose edges at higher 3D depth settings.
  • Updated 448x256 game-screen backgrounds are available in the snes9x_3ds-assets v1.1.0 release.
• Added save-state screenshot previews
• Added per-game crop/overscan control (#55)
• Added scanlines
• Added Mode 7 bilinear smoothing (#68)
• Added Frame Sync setting with VBlank/Sleep pacing options
  • Sleep Sync can make games run smoother when they stutter or won't hold full speed, e.g. DKC2 on Old 3DS.

Rendering & Compatibility

• Improved HDMA/in-frame palette compatibility for games with mid-frame palette changes (#73)
  • Helps games such as Top Gear and Super Turrican; see In-frame palette changes.
• Added mosaic rendering support (#70)
• Fixed stale core data after switching ROMs
• Fixed several game-specific rendering/timing issues
  • Includes fixes for Sim City intro, Jurassic Park transparency and Super Bases Loaded 2 crash.
• Optimized Mode 7 tile 0 blit (#67)

Audio

• Migrated audio output from CSND to NDSP and improved audio scheduling/stability (#58, 7ff81cc)
• Added audio buffer size setting
  • Lower values reduce latency; higher values reduce the chance of crackling.

Documentation

• Added KNOWN_ISSUES.md with compatibility notes for problematic games,
  Satellaview (BS-X) titles and common visual/audio issues.
