GSDX Front Mission 5 Jap shadows and dirty xor layer glitch

[GoogleCodeExporter]

--------------------------------------

1) The game run fine , the glitch was always here on trunk , branch
,official or non official build ( logaritmic Z is compulsory to fix other
glitches, alpha or other option did not change the situation , same for
speed hacks)

2) Just load the game , on the first 3d session you will get it ,(also in
the map mode ,just move around to see the dirty layer)

3) What exactly happens when you experience this issue (listing any console
errors or screen output you recieve)?

4)PCSX2 trunk or beta ,dont care , it is the same

5A) there are 2 glith on every 3d scene, the first is the xor layer on
front ground , is a trasparent layer with a shape of something on the screen.

5B) on the battle mode the shadows are merged and summed with the floor
texture.

The glitch completly disappears if you switch to the software render path

6) here the gsdx dump

Same issue on ATI or Nvidia Card, I think is indipendent from driver setting. 
DX9 or
10 is the same

On software render path all' is ok , I think is related only to gsdx and 
indipendent
from the hack of pcsx2

Odd, I get this display, no matter what (hw) renderer and settings I use. :

you still have the xor dirty layer but not the shadows glitch.

Your rendering speed is quite amazing

Could you try in software mode with 1 sw thread? , the glitch should disappears.

i notice that you are using the native resolution but your image is a lot less
shimmering and aliased than mine and also the texture are filtered. In fact i 
am not
able to select texture filter when native resolution is selected

the xor dirty layer seams a copy of the shadow buffer

Hm, ok, this might be a GS download problem then. Much like the Shin Megami 
Tensei
game's shadow issues.
We're aware of that, and a proper fix is being worked on (sometimes, so don't 
expect
one anytime soon :p ).

the r2058 svn fix part of the problem , now the xor trasparent layer is gone on 
some
scene , and the rendering is perfect.

But in the cut scene there still the garbage transparent layer , and also the 
shadows
are gone, there still the strange wrapping shadows on some cutscene and there 
still
the garbage on the strategy view during the game

Yeah, it fixes it by not running the pitch conversion.
So the bug is still there, it just may be hidden off screen somewhere.
Still working on this though, stay tuned :p

Original comment by tifal...@yahoo.com on 28 Dec 2009 at 5:03

[GoogleCodeExporter]

So whats the solution thus far?

Hello everyone. What's the status on this issue?! I'd love to see even a 
workaround.

How do I use the r2058 svn posted above? Do I have to compile it, if so can I 
do it 
in Visual Studio 2008 express edition?

Also for some reason the load state doesn't work for me (it returns an error) 
so I 
can't test that out. 

I am dying to play the game once more (since the fans translated it) but I 
can't 
stand the glitches on the map! :(

It's possible to fix it in the latest GSdx revisions.
You'll have to enable hacks in the ini, then set skipdraw to 5 or so.

Find a compiled build of GSdx somewhere if you want to play now.
Otherwise wait for us to release a beta.

The situation has improved recently.  At some point between r2680 and r2721, it
became (mostly) unnecessary to use the skipdraw hack for fixing the overhead 
battle
view.  There is still the occasional glitchiness during cutscenes (such as the 
sky in
the "new game" cutscene) and some levels still display a low amount of garbage 
on the
map.

I recommend EmuCR for getting compiled versions of recent revisions.

Actually, I may have been wrong.  It could just be that the darker maps are less
glitchy.  I'm now on a daylight mission and the glitches are back like before...
