BGB v1.5.6 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
