[GB/CGB] SharpBoy 0.4

Kirby Tilt & Tumble

v0.4 (May 31th 2011)

• Fixed compatibility regression with GBC DMA transfers, affects ex. Pokemon Puzzle Challenge
• Substantially improved MBC7 emulation via GEST's source code, Kirby Tilt 'n' Tumble is now playable
• Improved LCD Status interrupt generation, fixes faked high-color display in certain Game Boy Color games
• Some improvements in handling of disabled LCD; ex. Zelda: Oracle games no longer freeze when leaving the menu
• Improved timer emulation and improved emulation of HALT opcode, fixes ex. Stunt Race FX Demo
• Added Wii Remote support for input and Rumble, button configuration is fixed; MBC7 tilt sensor is controlled by Wii Remote when enabled
• When using keyboard control, MBC7 tilt controls can be changed via the GUI's control settings
• Added crude frame blending via OpenGL; blends currently drawn frame with previous frame to better simulate pseudo-transparency
• Added option to keep aspect ratio intact when resizing window; also double-clicking the game screen maximizes/normalizes the window
• Added drag-and-drop capabilities to GUI, ROMs can now be loaded by dropping them into the program window
• Very minor GUI changes

v0.3 (May 11th 2011)

• Switched rendering from using SlimDX to OpenTK, SlimDX Runtimes no longer needed; video filtering now selectable
• GBC DMA copy operations improved, fixes certain DMA transfers spanning different areas of memory
• Improved support for "undocumented" I/O registers, Demotronic Demo no longer detects the emulator and now runs with some glitches
• Above change, coupled with improved graphics emulation, also fixed colorization of monochrome games via the CGB bootstrap ROM
• Preliminary MBC emulation for Pocket Camera / Game Boy Camera; no actual camera support
• Frame skipping and speed-up functionality implemented
• ROMs can now be loaded from ZIP archives (using the DotNetZip library); recent ROM history added to menu

v0.2 (April 03rd 2011)

• GBC DMA emulation fixed, transfer length wasn't being calculated correctly; fixes incorrect and missing graphics in some games
• LCDC emulation improved, fixes flickering and slowdown in certain games and demos
• MBC5 ROM bank select fixed; many more Game Boy Color games now start and/or run further
• Timing of screen drawing improved, which results in less graphical glitches with ex. flickering sprites for pseudo-transparency
• Temporary hack added to allow the Zelda: Oracle games to boot correctly, coupled with the above fixes they now go in-game
• DMG and CGB bootstrap ROMs now supported; have to be named DMG_ROM.bin and CGB_ROM.bin and enabled via the menu
• Manual system type selection implemented, emulator can now be forced to run in GB or GBC mode (not complete yet)
• Controls can be changed via the GUI
• Other minor GUI and usability improvements (ex. path to last ROM image run is saved to config.xml)

v0.1a (March 30th 2011)

• Bugfix release, fixed possible crashes at startup

Notes and bugs:

• Emulation is still incomplete and has bugs, especially with GBC games
• No sound, serial link, SGB, etc. for now
• No documentation yet either; controls cannot be changed from within the program (edit config.xml manually after first run)
• GUI has some quirks (ex. window resizing), FPS limit and counter aren't accurate
• Debugger slows down emulation speed considerably, needs some serious optimization
• Probably more...
• ...and despite this, there's a bunch of playable games:
