JPCSP and Intel HD 3000

[Arill]

Hello there,

I found this great emulator and I can perfectly run games and yes, it's pretty much playable, with sound and everything. However, I'm having HUGE graphical issues (i.e. in the game Project Diva 2nd, only the head and hands of the models would appear, effects become black and flashing animations) and everything works well if I disable "Use shaders", but then the game becomes really slow. I tested on a friend's computer the same everything, except the graphics adapter, and on his it works fine, with no glitches at all.
Also, when I turn on Disable UBO, the screen changes it's color between black and white, but sound still play. What can I do to solve this issue?

Thanks in advance.

Unfortunately, these errors are known. See here:

gid15 found out the problems are related to bugs in the driver. I assume OpenGL is not a priority for Intel. You can only hope for new drivers.

BTW, commenting out the 2nd SetUniform Override showed a picture for me, but it was not faster with shaders as it was without shaders.

yeah unfortunately Intel OpenGL support is pretty lacking and is probably worse then ATI
you can see supported extensions here for each driver version and manufacturer, these will vary slightly depending on video card model.

so always make sure to use the latest driver as it could add more support.

Thanks both of you for the replies.
Darth1701, I changed the lines but now the emulator won't even boot hahah. I'm sure I did it wrong. I also noticed that the command prompt window don't print anything before the changes.
So, is there any way to fix these issues?

Just delete lines 355 through 363 in the StateProxy.java file and recompile. It should work. Try also to disable UBO when running games, somehow JPCSP doesn't detect Intel graphics doesn't support these.

As for a real solution: I think only Intel can provided a new & better driver.

I'll try it. Any progress noticed I'll post here. Thanks in advance

Sorry, but could I ask for a how to? I don't even know how to edit these lines...

@Edit:
I did as you said, and the graphics aren't glitched as they where before
Thank you. But the models still only show head and hands unless I disable Use shaders. Is there any fix to this?

I'm afraid I can't help you there. Maybe gid15 can help in creating some workaround but he is currently on vacation.
