v0.9.7

This patch introduces anaglyph mode, render time emulation, and numerous bugfixes.
Render time emulation means that some in-game sequences run at the same speed they did on a real Virtual Boy, which no previous emulator has emulated accurately. This includes the Jack Bros. level transitions being as choppy as they originally were, so a toggle has been added to revert to the old behaviour. For more information, check out my write-up.

• Added anaglyph mode, with configurable colours for each eye
  • 2DS users can configure a depth offset in anaglyph mode, as they have no depth slider
• Add render time emulation, including a toggle to turn it off
• Fix audio bug in Colony intro in Galactic Pinball
• Fix various issues in the Game Boy emulator
• Fix Red Alarm wireframe graphics drawing on top of UI
• Add a hack for Jack Bros. to make the intro chime play at roughly the correct speed
• Apply game fixes based on game ID rather than checksum, for better compatibility with ROM hacks
• Increased frameskip aggressiveness to improve performance in Elevated Speed
• Update software framebuffer more conservatively to improve performance in Waterworld and 3-D Tetris
• Adjusted gamma correction for improved visibility
• Fix D-Pad ABXY mirroring having an incorrect right input

v0.9.6

This patch adds an antiflicker mode and an input display.

• Added antiflicker option to mitigate image retention issues, particularly on IPS models
• Added an input display (buttons light up in red if turbo is enabled and blue if toggle is enabled)
• Fixed a critical bug where the emulator crashes when starting a game if the home directory doesn't exist

v0.9.5

This release features significantly improved input remapping.

Control changes

• New "Custom" control scheme (#67)
• In the Custom control scheme, any 3DS button can be mapped to any VB button
• Toggle and Turbo modes are available for each button
• The previous control menu is still available as "Preset" for its ease of use
• Added remapping option to 3DS D-Pad in Preset mode (#65)
• Virtual buttons on the touchscreen can now be set to the face buttons by default
• "Switch" button can now be turned off

Other settings changes

• Configurations can now be game-specific, including controls, graphics, etc
• Moved rv_config.ini to a more standard location (sdmc:/config/red-viper)
• The red-viper directory with savestates and per-game configs can be moved by manually editing rv_config.ini
• Added VBLink for homebrew developers, accessible by pressing Y on the main menu (will be supported in future versions of VUEngine Studio)

Other changes

• Improved stability for capture cards
• Fixed occasional bug where the emulator would crash on startup

v0.9.4

This release features savestate support, as well as a new splash screen. There are 10 savestate slots per game, and the savestates are stored in a "red-viper" directory on the root of your SD card.

• Added savestates (#59)
• New splash screen by Morintari
• Added a fallback interpreter when executing code from RAM to fix Formula V
• Fixed the reset button on the touchscreen config turning off the touchscreen
• Fixed the default file select cursor being offset in folders with subfolders
• Added toggle for New 3DS speedup

v0.9.3

This release features much smoother gameplay, partially thanks to running the 3DS displays at 50Hz! Also includes a number of compatibility improvements, especially with homebrew.

• Run 3DS displays at 50Hz (thanks to everyone in #46 who knows much more about this than I do!)
• Improve frame pacing by rendering on VBlank
• The image is now displayed in full 24-bit colour
• Various renderer optimizations, significantly improving performance in Elevated Speed
• Improved audio clarity
• Fixed issues with various sound effects in Wario Land
• Fixed compatibility hack for Virtual Lab's English patch
• Improved performance in Nester's Funky Bowling
• Compatibility fixes for lots of homebrew
• Add a confirmation prompt to Reset and Quit menu options
• Game progress is now saved when entering sleep mode

v0.9.2.1

This patch features fixes for a few critical bugs that snuck into v0.9.2, including the .cia not working on O3DS and the crash screen causing a ghost image when left alone for too long.
