Snes9x is a portable, freeware Super Nintendo Entertainment System (SNES) emulator. It basically allows you to play most games designed for the SNES and Super Famicom Nintendo game systems on your PC or Workstation; which includes some real gems that were only ever released in Japan. Snes9x is the result of well over three years worth of part-time hacking, coding, recoding, debugging, divorce, etc. (just kidding about the divorce bit). Snes9x is coded in C++, with three assembler CPU emulation cores on the i386 Linux and Windows ports.

SameBoy is a user friendly Game Boy and Game Boy Color emulator for macOS. SameBoy is extremely accurate and includes a wide range of powerful debugging features, making it ideal for both casual players and developers. In addition to accuracy and developer capabilities, SameBoy has all the features one would expect from an emulator – from save states to scaling filters. An SDL version is also available to Windows and Unix-like systems.
SameBoy v0.11.2 Changelog:
New/Improved Features
- Each debug console in Cocoa now displays the ROM file name in its titlebar
- SameBoy can now load RTC information from battery saves from different emulators including BGB, VisualBoyAdvance, and VisualBoyAdvance-M and vice versa. Older battery saves will automatically be converted
Accuracy Improvements/Fixes
- More accurate emulation of DAC charging and discharging. Fixes the buzzing sound heard in several games
- Fixed a bug where the left and right audio channel were swapped
- More accurate GDMA and HDMA timings
- Fixed several bugs, one of which is a regression, where channels 1 and 2 could play without a delay. Fixes missing audio in Gensan 2
- Correct emulation of enabling and disabling the volume envelope
- Correct emulation of a glitch where the volume envelope ticks when it usually wouldn’t
- Compensate for CPU prefetch in DIV’s initial value
- Correct emulation of turning the DACs on and off. Fixes missing audio in several games
Bug Fixes
- Fixed bugs in the debugger UI in Cocoa that made it unresponsive
- Fixed a bug where the libretro core didn’t save and load the RTC properly
RxNES has updated to v3.021. This release is an important update, and fixes the issue of generating gigs of data, due to constantly making new textures, where as now it now replaces existing textures, so should be reduced to a more manageable 500meg of ram.
This release also fixes issues to general emulation script RxEnhance.cs, which was getting confused in some rom emulation.
Also a call out to anyone who'd like to help with this project:
As you should know the main Enhancement script RxEnhance.cs is editable in a text/c# editor, and hopefully a user can optimize / improve it further and share with everyone else.
The sprites are rendered on their own layers, 1 layer for each of 4 screen palettes.
they are then cropped out for dumping.
This is the wrong approach, and sprites should be read from the cartridge and not from the screen; (but I spent weeks coding it this way). Problems arise when 2 sprites overlap each other and they dump combined and overlapping (Only if they use the same of 4 palettes).
Some sprites dumped are duplicates yet have different file names, cropping is over-cropped.
I dunno, I did my best effort on everything but I was really hoping for help from the community.
Lots of good things! The emu has tons going for it!
I just wanted to mention the bugs I would like to see fixed by users as I don't have a current interest in fixing them ('cause it doesn't run full speed).
Important to remember is that replacement graphics can be bigger than their original screen space, so the over-cropping issue shouldn't even matter if ppl are replacing the graphics with new ones anyway. The issue that remains is the corrupt sprites, if a sprite dumps at the same time as the nes is rendering it, it will be half and half of a frame and the frame before. This would cause the replacement sprite not to be used and the corrupted / incomplete sprite to flicker on.
Also, a good point, is that any .png can be replaced with a .obj 3d model. (For sprites and BG Tiles) Just make the .png trasparent and name the .obj the same hash fliename as the .png. The exact way it works is in the code and i'm just still waking up this morning.
I guess this is a call out to Unity3d coders to have a look at the RxEnhance.cs script and see if they can improve it. If you could with the release of this version, write up a call to coders to have a look and fix up the main script. (It compiles at Runtime :) )
Cemu is a Nintendo Wii U emulator that runs commercial games. Highly experimental software to emulate Wii U applications on PC.
Cemu v1.14.0b Changelog:
# New in 1.14.0b:

- Better performance when a large number of textures are loaded
- Better garbage collection in texture cache (lowers VRAM usage and keeps it low)
- Lower chance of corrupted textures due to improved detection of texture invalidation
- Avoid rendering to GL texture views since they have bugs on AMD and Intel drivers (fixes 'light circles' and similar issues)
GX2: Fixed shader cache being ignored on Windows AMD drivers
GX2: Fixed 'Nvidia artifacts' (e.g. BotW lava and water surfaces would have distorted pixels)
GX2: Primitive RECT are now rendered as triangles
GX2: Added support for shader CALL instruction
GX2: Automatically scale texelFetch() coordinates to match resolution defined via texture rules
GX2: Added support for streamout in geometry shaders
GX2: Emulate color buffer GPU7 registers correctly
GX2: Fixed separate alpha blending
GX2: Correctly clamp out-of-bounds LOD values in GX2InitSamplerLOD()
GX2: Fixed a bug were tiling aperature always assumed a tilemode of 4
GX2: Added support for texture formats R16_SNORM and BC4_SNORM
GX2: Fixed a bug where the first depth clear on an previously unknown texture was being ignored
GX2: Fixed slowdown when rendering point primitives (Mainly affected Mario Kart 8 and Fatal Frame 5)
GX2: Fixed random crash that could occur shortly after shader cache finished loading
PPC/JIT: Small tweaks and improvements
gfxPacks: V2 graphic packs that are not compatible with 1.14.0 will be marked as outdated

coreinit: Added API OSContinueThread, MEMGetAllocatableSizeForBlockHeapEx, OSSwapAtomic
coreinit: Small tweaks to OSExitThread
input: Fixed touch input in separate pad window
input: Improved deadzone handling
vpad: Fixed directions of axis values in certain situations
