Screen Issue - Render split screen?

[NyghtcrawleR]

This is a problem that the guys who are developing Wagic (link) are currently having. It is something that doesnt happen all the time but is a nagging issue and sometimes will happen all the time. Its rendering dual screens that are all purple. Its not supposed to do either.



Heres the log on the SVN: Issue 92 - wagic - PSP: Screen purple & divided in 2 at startup - Project Hosting on Google Code


This issue was also found by another dev awhile ago but no solution apparently found that works, at least not here: forums.ps2dev.org :: View topic - Weird screen behavior

Any help with this issue would be fantastic.

yeah, I had the same problem a while ago. so I just changed graphic libraries and it got fixed
the library I was using that caused this problem was the OSlib MOD by Sakya

Dont think that is the issue as Wagic uses the JGE++ libraries.

Sounds like another issue with the blitting... As seen before on wololo

Seems to be something with the blitting, problem is its something that nobody has been able to figure out yet.

I've had the same thing in a couple of apps. Road Dog was one of them.
Don't remember how I fixed it.
Multimesh was another, it used the Easy Accelerated Image Lib.

i use to have the same bug with one of my app. it seems it has to do with the GU of the psp. The problem i had it with the network dialog used by sony and the keyboard together in one code. It may have been something in the address of the bliting list and the dialog or something but i at least conformed for my self it definitely had to do with the GU. this may be why someone people had the same bug with the graphic lib and other with the oslib. If im right all use the psp GU lib to blit to the screen. I fix my bug by redoing it all over(The GU Part At least).

Note: by the way i thought it was kind of cool if it had proper colors and if we could define what is blited on each screen.
