Please test it! GS supports 3 formats for the output: 32 bits: normal case => no change 24 bits: like 32 bits but without alpha channel => mask alpha channel (ie don't write it anymore) => Always uses 1.0f as blending coefficient 16 bits: RGB5A1, emulated by a 32 bits openGL texture. I think it will be more correct to use a real 16 bits GL texture. Unfortunately it would cost several (slow) target conversions. Anyway as a current solution => apply a mask of 0xF8 on color when SW blending is used (improve Castlevania shadow) unfortunately normal blending mode still uses the full range of colors! This commit also corrects a couple of blending factor. 128/255 is equivalent to 1.0f in PS2, whereas GPU uses 1.0f. So the blending factor must be 255/128 instead of 2 Note: disable CRC hack and enable accurate_colclip to see Castlevania shadow ^^ (issue #380). Note2: SW renderer is darker on Castlevania. I don't know why maybe linked to the 16 bits format poorly emulated |

README.md
PCSX2 is an open source Playstation 2 emulator. Its purpose is to mimic the the PS2 hardware, using a combination of MIPS CPU Interpreters, Recompilers and a Virtual Machine which manages hardware states and PS2 system memory.
Project Details
The PCSX2 project has been running for more than ten years. Once able to run only a few public domain demos, recent versions enable many games to work at full speed, including popular titles such as Final Fantasy X or Devil May Cry 3. Visit the PCSX2 homepage to check the latest compatibility status of games (with more than 2000 titles tested), or ask your doubts in the Official forums.
The latest officially released version is 1.2.1 (SVN r5875). Installers and binaries for both Windows and Linux are available from our homepage.

System Requirements
Minimum
- Windows/Linux OS
- CPU: Any that supports SSE2 (Pentium 4 and up, Athlon64 and up)
- GPU: Any that supports Pixel Shader model 2.0, except Nvidia FX series (broken SM2.0, too slow anyway)
- 512MB RAM (note Vista needs at least 2GB to run reliably)
Recommended
- Windows Vista / Windows 7 (32bit or 64bit) with the latest DirectX
- CPU: Intel Core 2 Duo @ 3.2ghz or better
- GPU: 8800gt or better (for Direct3D10 support)
- RAM: 1GB on Linux/Windows XP, 2GB or more on Vista
Note: Because of copyright issues, and the complexity of trying to work around it, you need a BIOS dump extracted from a legitimately owned Playstation 2 console to use the emulator.
Note: PCSX2 mainly takes advantage of 2 CPU cores. As of r4865 PCSX2 can now take advantage of a 3rd core using the MTVU speedhack. This can be a significant speedup on CPUs with 3+ cores, however on GS limited games (or on dual core CPUs) it may be a slowdown.
