Features:
- Emulated Hardware:
*Game Boy B & W
*Game Boy Color
- Windows Forms UI
*Graphical debugger
*Map Viewer

- Rendering methods
*GDI+ (Slow)
*Direct3D (Using Managed DirectX, only works in 32 bits)
*Direct3D 9 (Using SlimDX, should work everywhere provided you install the SlimDX runtime)

CrystalBoy v1.4 Changelog:
* Now supports loading the DMG, SGB and GBC bootstrap ROMs
* Better GBC hardware emulation (now supports switching to fake B&W mode)
- Using GBC bootstrap ROM allows to play B&W games with automatic color palette
- The GBC automatic palettes are also emulated without the bootstrap ROM
- The OAM and VRAM are initialized more accurately
* MBC2 support (maybe not totally accurate, but certainly good enough)
* Instant FPS calculation… Should be instantaneously more accurate, but much more variable than the method used previously.
* Multithreaded emulation. (Should only improve uncapped FPS for now)
- I did not test extensively with all the rendering plugins, but things should be ok as the UI thread and and rendering thread never execute at the same time.
- Please send a bug report if you encunter a bug related to multithreade rendering…
* LCD and Timer timings emulation redone 95%…
- Compatibility increased
- Wario Land II startup screen now shows correctly
- Link's Awakening's bug seems to be gone
- Brain Bender's startup screen now render correctly, like it did a [very] very long time ago.
* Fixed the sprite priority emulation again… Pokémon Crystal intro should play fine.
* Fixed small - but sometimes nasty - bugs
- Now able to run Mental Respirator by Phantasy (The Gin & Tonic trick is not emulated yet)
- Most demos are able to start or even run correctly. (Demotronic still doesn't, but it helped correct one of the nasty bugs ;)
