Ce très bon émulateur GameBoy/GameBoy Color, surtout adapté à MacOS mais qui possèdent néanmoins un bon port Windows, a été mis à jour. Les améliorations sont les suivantes:
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
- Customizable palettes for monochrome models in the Cocoa frontend. Bundled with several new palettes as examples
- The bundled register names symbol file now correctly names several undocumented registers
- Improved performance by better utilizing Link-Time Optimizations
- 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
- Cartridge Instances now allow having multiple saves for the same ROM file in the Cocoa frontend
- The debugger apu commands now display a single channel
- 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
- General code optimizations for overall performance improvements
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 SDL fronted did not correctly load the palette setting
- 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
- Fixed SDL crashes on certain Linux systems
- Fixed UI issues on OS X Mavericks
- Fixed achievement supports in the Libretro frontend
- Fixed the 16x16 cartridge icon in both Cocoa and FreeDesktop
- Fixes audio glitches during the SGB jingle
- Visual fixes for the GBS player on macOS Big Sur and newer
Misc Internal Changes
- Improvements to the input hints API
- Added safe memory read API
- New memory write callback API
- New API to determine DMG-mode CGB
- Improved APIs to handle input
- New execution callback API
- New LCD line callback API
- An API for adjusting the RTC speed, for TAS verifications
- An API for detecting lag frames
- The direct access API now supports accessing the CPU registers
- An API for allowing illegal directional inputs
- General preparation for future support of different AGB revisions |
