Error loading emulator

[kprzy219]

Hello,

The only game I am trying to play is Sonic Adventure 2 Battle. When I try to run the game I get this error:

Quote:Failed to compile pixel shader!
This usually happens when trying to use Dolphin with an
Outdated GPU
or integrated GPU like the Intel GMA series.

If you're sure this is Dolphin's error anyway, post the contents of
./User/Dump/Bad_ps_0004.txt along with this error message at the forums.

Debug info (ps_3_0):
(15): error X4555: invalid type used for 'VPOS' input semantics

Here are the specs of my computer:
Dell Studio Laptop running Windows Vista
Processor: Intel® Core™2 Duo CPU @ 2.4GHz
Memory: 3066MB RAM
Graphics: ATI Radeon (0x95C4) HD 3400 Series
I also have DirectX 10

As you can see from the error message, it says that it is not compiling the pixel shader. The 3400 series of the ATI has Pixel Shader 4.1 which I found out here. To me it seems like my computer is up to date and meets all the requirements for running the emulator/game. I'm not the best with computers and gathering this information has taken me quite a while. Anyone able to help?

As requested in the error message:

Dolphin 3.0-678 and a few revisions after that have this issue when you have Per Pixel Lighting turned on.
Disable it, and it should work. The latest versions have fixed this issue.

Yeah, he's right.

Try another Dolphin revision, e.g. the Dolphin 3.0 release or the most recent dirty build (Here ya go -> http://www.dolphin-emu.org/download.html ) or disable Per-Pixel-Lighting.
