The Atari Jaguar console emulator has been updated - BigPEmu.

Version 1.221
- Added some cheap hash-based desync detection to the network protocol. The host will now be alerted when a desync occurs in State Sync mode. (desyncs are only known to occur when settings don't match across players or a script is causing emulation to operate non-deterministically)
- Removed unnecessary zlib dependencies from the network plugin in Linux builds. (thanks to SabreAZ for helping me test this)
- Added a -nomenubg command line option

Version 1.22
- Added a new "cheat_codes" script module. When this script module is active, the user will be prompted to toggle any available cheat codes (provided by cheat_codes.json) any time a software image is loaded. Cheat codes are provided for every cartridge and CD title in the Jaguar's retail library. Many of these cheat codes were adapted from jguff's BigPEmu scripting work, you can find the relevant scripts (and more) here: https://github.com/jguffer/BigPEmu_Scripts
- Implemented the Blitter GPU interrupt. (mainly for developers; this functionality isn't used in any retail software)
- Lots of new scripting API functionality, as well as some minor fixes/additions for existing scripts
- Reworked a bunch of BigMaster stuff under the hood. You may need to re-enter some of your BigMaster credentials when updating from a previous version of the application
- Fixed various potential bugs related to using per-game configs in network mode

The emulator GBA - NanoBoyAdvance will be updated.

- Core: Improved fast-forwarding, adding 2x, 4x and 8x options alongside infinite
- UI: Set default filter to nearest
- Platform: Upgrade to Qt 6
- Platform: Fix controller lag on macOS
- CI: Pivot Windows builds to MSVC, remove macOS Intel builds
- Remove broken links from README, remove COMPILING and move its instructions to README
- Update dependencies

What's new for v0.110b:

- Some Cycle consumption timing fixes
- Various emulation fixes relating to SRAM writes and ROM mirroring. (Fixes MMX copy protections)
- Added the ability to define custom paths to where you want to store your saves, .srm, .cht, and .bps files
- Added the ability to disable the last save state
- Added the ability to disable save history

- [Android] Add DPad touch sensitivity (movement and distance sliders)
- [Android] Fixed filename formatting in quick load
- [Android] Added icon that was missing on certain devices

The latest Sega Saturn emulator - Ymir, has been updated.

New features and improvements
- Debugger: Add Priority Stack to VDP2 debug overlay
- VDP2: Various performance optimizations to the software renderer, improving performance in graphics-bound games (especially in high resolution modes). Technical details:
 - RBG1 was being unnecessarily rendered when NBG0 was enabled and RBG1 was disabled
 - Remove redundant transparency bit since priority zero acts as transparency
 - Remove various unused function arguments, reducing CPU register and stack pressure
 - Pass down VDP2 register references as arguments rather than fetching them from scratch everywhere
 - Reuse line data (i.e. skip recomputing lines) when rendering vertical mosaic
 - Bit-pack character pattern data in a single 32-bit value
 - Microoptimize scroll coordinates calculations
 - Rotation parameter table calculations:
  - Specialize calculations for (1) no coefficient table, (2) per-line coefficient table and (3) per-dot coefficient table
  - Hoist coefficient table enable and per-dot coefficients checks out of the loop
  - Make the inner loops SIMD-friendly
  - Avoid unnecessary computation of transparency and line color screen data if they are disabled
 - Microoptimizations to the compositor function:
  - Layer sorting now uses a combined key
  - Gather layer data in one single loop
  - Pixel fetching is now templatized and some bail out checks are done earlier
  - Color offset calculation enable flag is cleared in the fetch loop if no offset is actually applied

Fixes
- Debugger: Various SH2 stack analysis fixes
- Game DB: Add slow VDP1 flag to Funky Fantasy to fix slow FMVs
