sound output: waveout, directsound, null, and disk writer supported.

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).

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.

How to make bgb run faster if you have a slow computerĬlick the right mouse button in the emulator window to get the popup menu, from which you can access the options and functions.

If you choose to do so, that is your responsibility.Įxpressions, breakpoint conditions, and debug messages Using copyrighted roms with an emulator is illegal if you don't own the real cartridge or have explicit permission from the copyright holder. Don't blame me if it damages your computer, or erases your hard drive, etc. This program is guaranteed to do nothing but taking disk space. No warranty of any kind, use at your own risk. This is a gameboy/color emulator/debugger for win32 which will probably never be finished
