Debuggers / Special Emulators


A Gameboy/GBColor Emulator with debugging 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)

symbols (SYM file) support

“inline” editing in code, data, and stack viewer


break on access

conditional breakpoints

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

source code breakpoints (ld b,b)

singlestepping/tracing/animating/step out/step over

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

IO registers viewer

live display of data during emulation and freezing of ram values

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, DirectDraw, Direct3D, OpenGL, null output

- Graphics doubler: HQ2X, Scale2x, scanlines filter, blocky

- Sound output: waveout, directsound, null, and disk writer supported. support for writing the 4 channels to separate wav files

- Screenshot animation recording that is synchronized with the wav writer and can be converted to a video using avisynth

- Runs almost all roms perfectly, compatibility comparable with the best GB/C emulators

- Accurate/high quality sound emulation, bandlimited synthesis

- 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

- Good OS/platform compatibility/low requirements

- Support for optional border bitmap and pseudo and real fullscreen modes.

- TCP/IP game link support
