graphics doubler: HQ2X, Scale2x, scanlines filter, blocky.

graphics output: GDI, DirectDraw, Direct3D, OpenGL, null output.

joypad window allows simulating button presses at any time while debugging.

ability to modify all registers and state at any time.

break on exceptions (accessing inaccessible VRAM, read unitialized RAM, echo ram access, access locked external ram, disable lcd outside vblank).

live display of data during emulation and freezing of ram values.

vram viewer: BG map, tiles, OAM, palette.

singlestepping/tracing/animating/step out/step over.

'on jump' access breakpoints for breaking before a jump into a range is taken.

'inline' editing in code, data, and stack viewer.

assembler (change code and ability to save modified rom).

disassembler with syntax selectable from: no$gmb, rgbds, wla.

can run a GBC rom as on a DMG, and a DMG rom as on a GBC.

accurate emulation of the differences between DMG and GBC, including timing differences, differences in hardware behavior, initial state, etc.

correct memory access timing (access happening at the last/second to last clock of an opcode).

clock exact emulation of sprites causing mode 3 to take longer.

emulation of inaccessible VRAM and OAM as on real hardware.

accurate emulation of LCD register writes during scanline (prehistorik man, demotronic demo).

realistic initial ram values - random but with specific bit patterns, and simulated values left by bootroms (for example 'nibbler (pd)' depends on this).

clock exact timing of LCD behavior/state changes.

accurate emulation of the hardware, based on research with lots of test roms, useful for debugging/rom development.

emulation of the GameBoy, GameBoy Color, and Super Gameboy.Because of BGB's high emulation accuracy, if your rom works in BGB, it will most likely work on hardware too. In addition, it contains a debugger that lets you analyze/look into the emulation, create cheat codes, and assist in creating and modifying roms. It does this with many features that give a good gameplay experience, such as gamepad support, high quality sound and graphics, smooth Vsync animation, and low latency. Within: features downloads documentation īGB is a Gameboy emulator, a program that lets you play Gameboy and Gameboy Color games on a pc. (current version: BGB 1.5.9 - download below) BGB is a GameBoy emulator/debugger which runs on Windows and Wine.
