What's new in 1.19
------------------
- Audio
- Brand new sceAtrac implementation, fixing Flatout and multiple other long-standing issues! ([#20098], [#20136], [#20138], [#20162])
- More correctly implemented sceAtrac-through-sceSas functionality, fixing voice in Sol Trigger and multiple minis ([#20156])
- Better support for using sceAudiocodec directly, fixing music in some homebrew apps ([#20199], [#20246], [#20253], [#20209])
- Rendering fixes and performance
- Software depth buffer rendering added to fix lens flares in multiple games efficiently (Midnight Club LA, Wipeout, Syphon Filter etc) ([#19748], [#19764], [#20231], [#19955], etc)
- Multiple rendering-related crash fixes ([#20270], [#20346], [#20344], ...)
- Texture replacement load speed corrected and can now be controlled ([#20286]), regression fix for zipped packs ([#19860])
- Additional assorted compatibility and other fixes ([#20070], [#19685])
- Persona 1/2 readback fixes ([#20067], [#20068])
- Other correctness fixes ([#20233], [#20255], [#19686])
- Control and input
- Touch gliding ([#19983])
- New ImGUI-based PSP debugger: ImDebugger
- Allows very rapid development of debugging features as-needed, and also implements a pretty good Ge debugger for stepping through draws.
- Unlike the old Win32 debugger (but similar to the unmaintained web debugger), works on all platforms (though cumbersome on touchscreens)
- ([#20242], [#20240], [#20294])
- Multiplayer
- Added Infrastructure multiplayer support, with automatic DNS configuration ([#19865], [#19869], [#20221], [#20220], [#19875])
- Implement more of sceNet (prerequisite for the former feature).
- Socket re-mapping implemented ([#19827])
- Assorted bugfixes, thanks ANR2ME ([#20247], [#20245], [#19843], [#19849], [#19836])
- UI
- Loading spinner now actually spins properly, the app no longer appears to hang
- Minor features: Asks for confirmation on exit in most scenarios ([#19996], [#20023]), DPI scaling ([#20013]), can pause without menu ([#19883])
- As usual a lot of tweaks, perf fixes, and fixes for hangs and crashes ([#20343], [#20332], [#20305], [#20303], [#20299], [#20163], [#20152], [#20143], [#20079])
- Two new color themes ([#20334], [#20335]), related themability fixes ([#20308])
- Allow simultaneous DInput and XInput input ([#20347])
- Add "Move to trash" deletion funcionality to multiple platforms ([#20230], [#20261])
- Add ability to take "raw" screenshots of gameplay ([#20029])
- More files can be loaded directly from ZIP ([#20243])
- Developer Settings are now tabbed for easier access ([#20033], [#20228])
- Switch to the full libpng API so we can disable gamma correction, like the real PSP ([])
- Platform compatibility
- Exclude older Macs from using Vulkan (too many black screens, hangs) ([#20236])
- Use portable-file-dialogs to provide file-open dialogs on Linux ([#20175])
- "Cache full ISO in RAM" is now correctly hidden where it doesn't work ([#20165])
- Now rendering at proper resolution on newer Macs ([#20011])
- Mouse input improved on Android, including separate button mapping ([#19915])
- Use the correct font again on Mac/iOS ([#19874])
- Multiple file access optimizations made to make the most out of the flawed foundation called Android Scoped Storage ([#19668])
- Emulation
- Allow disabling HLE on a per-module basis (if games ship the module so we can load it). Enabled for sceCcc ([#20218]), and more importantly scePsmf ([#20208]), fixing multiple issues.
- Fix smoke effects in Jak'n'Daxter by re-using the fix from Ratchet & Clank ([#20032])
- Additional module loading improvements ([#20114], ...)
- More precise sleep function on Windows ([#20054])
- More replacement texture improvements, allow replacing game icons ([#19975], [#19978])
- Disable certain features like fast-forward when networking is on, to avoid de-syncs ([])
- Fixes mono Atrac3 as video soundtrack ([#19800])
