Apply an aggressive set of ultimately deterministic optimizations to
raster image files where an actual file size reduction of not less than
50% was possible without the removal of intrinsic properties such as
alpha channels. Rendered image dimensions were always left unchanged.
The primary mechanisms employed during optimization are:
- PNG color mode conversion from TrueColor to indexed palette
+ Accomplished using NeuQuant neural-net color quantization algorithm
- Stripping of data blocks containing irrelevant information, such as:
+ XMP metadata fields
+ Embedded comment fields
+ ICC color profiles (simple graphics with basic color schemes only)
+ EXIF profiles
- Re-compression using "best" or "smallest" profile presets
All modifications are performed on lossless image formats and closely
visually inspected after processing to ensure no loss of apparent
details or introduction of new, unwanted artifacts.
Toolset used:
- RIOT (Radical Image Optimization Tool), v2024.1.0 64-bit
- AdvanceCOMP (part of the Advance Projects), v2.6 64-bit
- optiPNG, v7.9.1 64-bit
- PNGOUT, v2015.02.13 32-bit

* for iOS: update launch screen to match UI
* use higher resolution invader
* adjust Y constraint (diff invader body proportion)
* for iOS: update Launch Screen to match app icon/ui
* update iOS icon—match shadow on other platforms
* icon source svgs to media folder for others’ reuse
* iOS App Icon revision, fix asset index mismatch
* iOS/tvOS: bundle cores as frameworks as opposed to dylibs
* iOS/tvOS: update plist to indicate controller support
* iOS/tvOS: living within the sandbox
* iOS/tvOS: import content through share sheet
* iOS/tvOS: default audio sync off due to crash on background
* iOS/tvOS: don't try altkit if there's no reason to
* iOS/tvOS: enumerate cores for appstore distribution
ever implemented for OpenGL2 driver, lots of code debt, best to
instead just keep improving the overlay system instead which is
already available for most video drivers
Replaced many blurry app icons, instead using icons from higher resolution sources.
Revised iOS app icon color & spacing slightly, attempting to match the pattern used in the recent Android and Switch versions of RetroArch.
* Support for Swift, added emulator keyboard
* fixed toggle key handling using magic number hack for now
* fixed keyboard transparency slider for now with suboptimal fix; add gesture recognizer to hide/show keyboard
* Support CocoaView extensions in Swift; move keyboard delegate impl and setup to swift extension
* moved keyboard view model creation out of EmulatorKeyboard
* implement key pressed delegate in swift extension
* added input method for directly sending RETROK_* codes to support a touchscreen keyboard; assign keyboard model delegates; updated keyboard layout (added F1-F12 keys); change shift, control and alt keys to be modifiers
* enable focus mode when custom keyboard is shown; enable/disable overlay when custom keyboard is toggled
* Specify -DHAVE_OPENGLES2 instead of -DHAVE_OPENGLES3 since glsym_es3.h does not compile in iOS 14.5
Fix tvOS build using compiler flags
* Create new project for iOS 13 deploy target; add check for deploy target to conditionally compile for new iOS 13 specific feature (custom keyboard)
* force disable core info caching for iOS, use opengl es2 for debug
* Add flag for iOS custom keyboard - 3-finger swipe up to show, 3-finger swipe down to hide
* use OpenGLES2 instead; using ES3 results in compile time errors on iOS 14.5
* code cleanup
* Updated references to -DDONT_WANT_ARM_ASM_OPTIMIZATIONS flag
* Add JIT support for non-jailbroken devices
* iOS: Add support for touch mouse handler
* Added a HAVE_IOS_TOUCHMOUSE preprocessor macro so that it builds under the iOS11_Metal xcode project
* Changed click-and-drag behavior to double tap hold and drag
* Visual improvements to the emulator keyboard: updated colors, improved key-press effect
* Add intrinsic NEON versions for float_to_s16/s16_to_float courtesy
of davidgfnet
* Define -DDONT_WANT_ARM_OPTIMIZATIONS for resampler sinc - this should
default to intrinsic versions
* Default to ARM NEON intrinsic codepath and make the ASM codepaths
optional by defining HAVE_ARM_NEON_ASM_OPTIMIZATIONS
* (Pkg/apple/Android) Take out ASM files being compiled in
