A gameboy emulator written in Pure Lua. Approaching feature completeness, but still a work in progress. This is designed to be fairly cross platform, and currently consists of a platform-independent gameboy module which contains the emulator, and a Love2D interface, presently the only supported platform.
Supported Features
* Pure Lua! Gameboy module should work on any Lua 5.2+ environment with the "bit" library available.
* Original Gameboy (DMG) and Gameboy Color (GBC)
* Decently cycle-approximate graphics
* Working 32KHz audio
* Multiple Palettes for DMG Mode
* SRAM and Save States
* Debug Panels for VRAM, Audio, IO and Disassembly
* Built-in filebrowser, drawn in software for easy porting
Notable Missing Features
* Super Gameboy support (planned)
* Serial Transfer port
* RTC Timer (Pokemon Gold / Crystal)
* HDMA Transfers (Used by a very small handful of games, notably Shantae)
LuaGB v0.1.1 Changelog:
Now targets Love 11.2
LuaJIT settings optimized for a rather hefty performance boost. Credit to @nico-abram, @TannerRogalsky and @meepen for the suggestions.
Less unpack, more FFI. Several small speed improvements from light code reorganization
Audio now routes through QueueableSource, greatly reducing skips, pops, and latency when running fullspeed
Proper support for General Purpose and HBlank DMA, needed by a few popular CGB games
binjgb is a Gameboy emulator implemented in C. It's a simple GB/GBC emulator.
binjgb changelog:
* Fix high DPI rendering on MacOS
* Remove deprecated texture2D function from shader
* Merge pull request #17 from binji/shader-version
* Prepend shader version; avoid deprecated features
* Merge pull request #15 from aconbere/anders/fix_compile_errors_on_osx
* use PRIu64 as advised
* Fixes compile errors for implicit instantiation on osx
* Fix bugs I introduced in the last commit
* Clean up demo.js some more
* Use ES6 classes in demo.js
* Use idb library in demo.js
* Update wasm module after bg priority fix
* Fix bg priority bug
* Allow the UI to capture the keyboard
* Add delete button to JS demo
MAME stands for Multiple Arcade Machine Emulator. When used in conjunction with images of the original arcade game's ROM and disk data, MAME attempts to reproduce that game as faithfully as possible on a more modern general-purpose computer. MAME can currently emulate several thousand different classic arcade video games from the late 1970s through the modern era.

Mednafen is a multi-game-system emulator, for various platforms, including emulation of the following systems:Atari Lynx,Famicom,GameBoy (Color),GameBoy Advance,Neo Geo Pocket (Color), NES(both NTSC and PAL),PC Engine/TurboGrafx 16 (CD) and SuperGrafx,PC-FX,WonderSwan (Color).
Mednafen v1.22.2 Changelog:
Apple2: Added basic support for WOZ 2.0 floppy disk images.
Lynx: Fixed a potential security vulnerability.
PCE: Fixed an an old regression(from around 0.9.0) that degraded DDA sample playback when playing a HES file.
PS1: Fixed a regression introduced in 1.22.0-UNSTABLE that broke a few PS1 games(e.g. "SimCity 2000" and "Rise 2").
SS: Added the European release of "Theme Park" to the internal database of games to use the data cache read bypass kludge with, to fix infinite boredom during the intro FMV.
Snes9x is a portable, freeware Super Nintendo Entertainment System (SNES) emulator. It basically allows you to play most games designed for the SNES and Super Famicom Nintendo game systems on your PC or Workstation; which includes some real gems that were only ever released in Japan. Snes9x is the result of well over three years worth of part-time hacking, coding, recoding, debugging, divorce, etc. (just kidding about the divorce bit). Snes9x is coded in C++, with three assembler CPU emulation cores on the i386 Linux, macOS and Windows ports.
The biggest changes in this release are some reversions which fix a couple games, some accuracy improvements which fix a couple more games, and some optimizations that speed things up a bit.
The Windows port now has an extra "Hacks" settings dialog that allows enabling some settings to allow older ROM hacks to work. The GTK port's hack settings are still hidden behind the -Ddangerous-hacks=true compile flag. The libretro port has had the remaining hack added. Use with caution and don't submit bug reports associated with enabling these hacks.
- Fixed subscreen blending with master brightness < 100%.
- Fixed NMI timing when toggling enable bit. Fixes Chou Aniki--hack removed.
- Reverted an IPL map optimization that misses a weird edge case that caused
The Great Battle III to lock up.
- Clamp MSU1 addition to max amplitude instead of wrapping. Proper MSU1 tracks
will not be affected by this.
- Save mipmap_input parameter with customized GLSL and slang shaders.
- Actually use mipmap_input parameter.
- Optimized subscreen math with help from Dwedit.
- Revert to measured APU clock speed instead of nominal speed. Fixes An
American Tail.
- Fixed broken BPS patch support. (ArtiiP)
- Fixed MSU1 track restarting on load state.
Win32:
- Changed window flags to allow NVIDIA cards to auto-enable exclusive
fullscreen mode in OpenGL.
- Added a hidden option "DWMSync" that allows OpenGL to sync to the window
manager while in windowed or borderless windowed mode.
- The automatic frame skip option no longer limits to 59.94Hz.
- Fixed bad icon scaling.
- Added a hacks dialog to enable settings for older hacks to run.
libretro:
- Added ability to use Satellaview data in same directory as ROM.
- Fixed deviation from proper libretro spec.
- Added option to use the software NTSC filter. (stellarporter)
GTK:
- Added icons to the entries to clear binding assignments.
- Fixed overlap in xBRZ multithreading.
- Changed glFenceSync option to an OML_sync option that works better.
- Fixed accumulation of partial pixel data on mouse motion when we update the
mouse position more than once per frame.
- Allow one key to be bound to many controller buttons on the same controller.
- Force menu and button icons.
- Add the view menu to right-click when SNES mouse isn't used.
- Remove unused status bar option.
- Startup background can be changed in snes9x.conf.
- Improved PortAudio driver.
Unix:
- Fixed sound output that broke with APU refactor.
