Cemu 1.15.7c

Wii U模擬器 Cemu 發布新版，更新如下 :

# New in 1.15.7b:

CPU/JIT: Fixed a bug leading to random corruption of the instruction stream

# New in 1.15.7:

general: Added visual indicator at game boot which displays the used controller profiles
general: Added controller low battery warning (can be turned on/off in settings. Off by default)
general: Global precompiled shader setting should no longer reset to auto (#63)

general: The internal process of updating system.xml is now more robust
         Previously there was a slim chance to lose all settings when Cemu crashed or was force closed
         while settings.xml was being updated

CPU/JIT: Optimized recompilation. This process is already fast enough to generally not be noticeable but
         it can lead to delay and micro-stutter in cases where a lot of new code is recompiled at once
         Examples where the bottleneck becomes apparent:
            Frame drops or audio crackle on first loading screen
            Initial delay when booting a game
         With the optimization, these should now be slighty less severe

GX2: Improved the accuracy and behavior of GX2WaitForFlip + GX2SwapScanBuffers
     This fixes an issue where games would run at the wrong framerate (e.g. Paper Mario Color Splash)

GX2: Fixed a bug in texture decoder for format BC4 (#59)

GX2: Fixed an issue where Cemu would crash if a game setup invalid shaders
     This resolves crashes in Pikmin 3 and Yoshi's Woolly World

Cemu 1.15.6c

Wii U模擬器 Cemu 發布新版，更新如下 :

general: Fixed a bug where default game profile options would be applied even if no game profile existed

GX2: Added a fast path for software texture copies when both the source and destionation texture use tilemode 4 (improves performance in Lego games)

# New in 1.15.6b:

general: Restored compatibility with cemuhook custom timers
general: Fixed broken bicubic and hermite upscaling/downscaling filter

CPU/JIT: Always correctly emulate single-precision operations (fixes softlocks and gameplay bugs)

# New in 1.15.6:

general: Reworked UI and removed deprecated options
         Experimental menu is gone and RDTSC is now always on
         Removed support for conventional shaders (always use separable shaders)
         CPU timer mode is now always 'host based'

general: Added UI to configure game profiles (accessible via right click on an entry in game list)
         Includes option to set controller profiles (#17)

general: Added tooltips for some of the settings

nsyshid: Implemented HIDWrite()
nsyshid: Use packet maximum size provided by device instead of a fixed value
nsyshid: Accuracy tweaks in HIDRead()
         These changes should improve support and increase stability for Skylanders and Lego USB portals

coreinit: More tweaks to MEM2 heap size to fix Lego games (#48)

Note:
(#xx) refers to bug tracker issues fixed by this change. See http://bugs.cemu.info/projects/cemu/

bsnes-hd beta 5

SFC/SNES模擬器 bsnes 非官方改版 bsnes-hd 發布新版，更新如下 :

Name change:
The project is now named "bsnes-hd", as "HD Mode 7 mod" was simply too long. Also I have moved beyond just Mode 7 and have plans for more. A repository will be available soon.
​
New features:

1.
Widescreen for non-Mode 7 backgrounds. Results of course vary between games and even scenes.
To avoid HUDs repeating and other unwanted effects I have added settings to disable widescreen for the separate background layers and even just the top or bottom of a layer.
The default is always "on" for all 4. Sample values for some games are:
"F-Zero": BG3: "off"
"HyperZone": BG2: ">80"
Please post settings for other games here.
​
2.
Sprites that are partially inside the non-widescreen area are now drawn entirely when possible.
The new "unsafe sprites" settings allow sprites to enter widescreen areas further if the game keeps updating them. This will however cause significant artifacts in many games. If ROM-hackers want to discuss optimizing games for this, feel free to contact me.
​
3.
more widescreen aspect ratios (16:10, 21:9, ...)
​
Known issues:
- Setting very high scale factors and a widescreen AR at the same time causes the emulator to terminate. The solution would be increasing the size of the arrays that store the pixels. That, however, causes lower frame rates at any settings. So I won't fix this, until I can do so without impacting performance for everyone. My lack of C++ experience makes this difficult. Maybe someone can help me out here.
- (edit) The logo intro of Donkey Kong Country crashes in widescreen.
