BGB v1.4

BGB v1.4 is released. BGB is a gameboy emulator which runs on Windows.

Features:
emulation of the GameBoy, GameBoy Color, and Super Gameboy
accurate emulation of the hardware, based on research with lots of test roms, useful for debugging/rom development. some highlights:
clock exact timing of LCD behavior/state changes
realistic initial ram values - random but with specific bit patterns, and simulated values left by bootroms (for example "nibbler (pd)" depends on this)
accurate emulation of LCD register writes during scanline (prehistorik man, demotronic demo)
emulation of inaccessible VRAM and OAM as on real hardware
10 sprites per line limit
clock exact emulation of sprites causing mode 3 to take longer
correct memory access timing (access happening at the last/second to last clock of an opcode)
accurate emulation of the differences between DMG and GBC, including timing differences, differences in hardware behavior, initial state, etc.
can run a GBC rom as on a DMG, and a DMG rom as on a GBC
powerful debugger:
disassembler
assembler (change code and ability to save modified rom)
breakpoints
break on access
conditional breakpoints
singlestepping/tracing/animating/step out/step over
vram viewer: BG map, tiles, OAM, palette.
IO registers viewer
break on exceptions (accessing inaccessible VRAM, read unitialized RAM, echo ram access, access locked external ram, disable lcd outside vblank)
ability to modify all registers and state at any time
joypad window allows simulating button presses at any time while debugging
SGB multiplayer with up to 4 gamepads
graphics output: GDI (DIB), DirectDraw, Direct3D, OpenGL, null output
sound output: waveout, directsound and disk writer supported. support for writing the 4 channels to separate wav files
runs almost all roms perfectly, compatibility comparable with the best GB/C emulators
Accurate/high quality sound emulation, bandlimited rectangular wave synthesis for perfectly smooth sound
accurate video emulation including "high color" graphics, correct sprite/background priorities, 10 sprites/line limit, and mid-scanline register changes.
This emulator is fast.
Joystick/Gamepad support, everything mappable to every button
some user interface keys are configurable and can be mapped to joystick/gamepad buttons
MBC3 Real Time Clock emulation. RTC is saved/loaded in the .sav file, compatible with VBA
Auto delay/frameskip, emulation runs at 100% real speed and full 60 fps
GameGenie and GameShark cheat, load/save cheats (auto and manual), "cheat searcher", easy creation of new cheat codes
save/load state with quick (zsnes style) keys.
Load from ZIP and GZIP files
This program does not require DirectX or runtime libraries.
support for optional border bitmap and pseudo and real fullscreen modes.
limited TCP/IP game link support



BGB v1.4 Changelog:
- greatly improved game link accuracy, most games should now work perfectly.
- added optional HQ2X and Scale2x graphics filters
- various accuracy improvements including sound registers, joypad timing, and lcd/interrupt timing
- Performance/efficiency improvements including waitloop detection and more efficient high quality sound rendering and others
- Major debugger improvements: Supports SYM files containing debug symbols. "on jump" access breakpoints. immideate entry of data into assembler, data, and stack viewer. improved assembler flexibility. Multiline code/data entry window. Keyboard shortcut for navigation to previous/next breakpoint, label etc. Live update memory mode. edit IO map registers. Fixed causes of accidental running while debugging.
- Sound quality improvements: CH3 and CH4 are now bandlimited in high quality mode. Improved DC offset accuracy. fixed sound timing inaccuracies.
- Improved WAV writer + screenshot recording. Fixed audio/video desync problems. Exported files are now better named.
- fixed windows 98 compatibility problem. eliminated requirement for DX9. improved wine support.
- New truecolor/hi-res icon.
- Many small bug fixes and improvements.
