SameBoy 0.15.1

Game Boy / Game Boy Color / Super Game Boy模擬器 SameBoy 發布新版，更新如下 :

This version is backwards compatible with save states from SameBoy 0.14.3 and newer, as well as save states from any BESS compliant emulator

New/Improved Features

• Improvements to the updater mechanism in the Cocoa port, should handle both Gatekeeper and write permissions better
• The SDL frontend now allows switching between audio drivers, rather than defaulting to the “best” supported driver
• The Windows XAudio2 drivers now use the system’s default sample rate, which prevents audio resampling and improves the audio quality

Bug Fixes

• Fixed SameBoy crashing on launch on Windows 8 and Windows 8.1 machines

Misc Internal Changes

• Fix code signing when locally building release builds of SameBoy on ARM-based Macs

Version 0.15

This version is backwards compatible with save states from SameBoy 0.14.3 and newer, as well as save states from any BESS compliant emulator

New/Improved Features

• Improved UI for the VRAM Viewer’s palette and object views

• The Memory Viewer, as well as the debugger examine command, no longer trigger side effects when reading from memory
• The Develop menu in the Cocoa frontend now lists options to hide or show the background or object “layers”
• Introducing PPU “fast paths”, improving performance by up to 34% with no accuracy losses
• Removed the use of slow floating point arithmetics in the APU code to improve performance
• Introducing lazy APU output generation, improving performance by up to 17%
• Link-Time Optimizations are now enabled for Windows build, significantly improving performance on Windows
• A new dma debugger command
• Improved the performance and responsiveness of the Cocoa VRAM Viewer and Memory Viewer
• New icon, minor visual refresh across both the Cocoa and SDL frontends

• Audio recording is now available in both the Cocoa and SDL frontends
• The SDL frontend now uses XAudio2 on Windows, when available
• The more common rX hardware symbol naming scheme now replaces the IO_X scheme; the latter remains supported

Accuracy Improvements/Fixes

• The Game Boy Pocket/Light is now available for emulation
• Every CGB revision is now available for emulation, adding CGB revisions 0, A, B and D
  • An option to select the CGB revision is now available in the SDL port
• Added MBC7 support
  • The mouse, as well as a joystick, can be used for motion controls
  • On the Cocoa frontend, a supported controller’s motion controls can be used as well
• Accurate timing of clearing bits in the IF register
• Improved accuracy of LY change timings
• Improved accuracy of the LY=LYC condition in revisions prior to CGB-D
• Improved emulation of a glitch that makes channel 3 use the CPU’s address bus as an index to the wave sample buffer
• Fixed an incorrectly emulated theorized glitch where writing to VRAM in certain timings would corrupt data
• Improved emulation of the TILE_SEL glitch
• Major improvements to DMA, HDMA, and GDMA, including timings, revision differences, interaction with halt/stop, and all sorts of bus conflicts
  • This allows pixel-perfect emulation of certain demos, such as It Came from Planet Zilog
• Improved IR modelling, fixes Gen 2 Pokémon Mystery Gift
• Added MMM01 support, including Mani carts
• Improved emulation of channel 1/2 “zombie stepping”
• Improved serial accuracy
• Correct emulation of how SCX prolongs mode 3
  • Including emulation of “SCX banging”, which can disrupt the PPU state machine and, on a real device, damage the LCD
• Improved emulation of object timings where X=0
• Fixed a regression where MBC5’s initial ROM bank was not 1
• Improved emulation of the Game Boy Camera MBC
• Improved HuC-1 emulation, fixes a Robopon Japanese Prototype ROM

Bug Fixes

• Fixed a bug in the Cocoa frontend where screenshots with filters applied would come out blurry on Retina displays
• Fix several instabilities in the Cocoa audio driver
• Fixed a bug where certain writes, when emulating CGB-C, would corrupt the emulator state

• Fixed a bug where the debugger undo command was available while not stopped
• Fixed GDMA being used incorrectly in SameBoot
• Fixed a bug where the obscured object indicator did not function correctly in the VRAM Viewer’s object view
• Fixed the Preserve Waveforms setting, now it behaves as intended
• Fixed a bug where closing an instance connected via serial to another instance would not behave correctly in the Cocoa frontend
