ProQuake 4.70 PSP Build

[drm_wayne]

Do you think it is possible to add the nice dithering effect from the goldsrc or dquake engine to your playstation portable engine?
And the imageloader from dquake (jpeg)?

In the last 5-6 pages of this thread, you can find external texture format info and the discussion about that.

I'm not sure what the dithering is from goldsrc/dquake. Does this have a cvar name in DQuake? I really have no idea what this is.

I'd need to see a screenshot and get a description to know what that is.

[drm_wayne]

Oh sorry, it was not Goldsrc, its indeed called "portablesrc"...


Same for DQuake, but they are both very instable on the psp.

I am not 100% sure but that dithering seems to be some kind of "make look your gfx better filter" selectable from the optionsmenu in the psp engines.
Some commercial games seems to use this technic in their games too (Phantasy Star Portable 2 and some more).
My PSP is not here but i can make a screenshot later if you want.

Dithering ON:



Dithering OFF:



And yes, its in the Options menu of Portablesrc and DQuake

[Baker]

What is option name in the menu? I don't have a slim so loading up either of these engines and looking is something I cannot do.

[drm_wayne]

Dithering ON/OFF, in both engines
I think there is a Phat build too from DQuake.

[Baker]

I have to look and see what that feature is. Could be just a texture filter. Or might be something more complex.

[ceriux]

don't add it if it eats up needed memory..

Tutorial on adding r_dithering based off the implementation.

[drm_wayne]

thx, got it working now
The only problems now are the palette problems when switching from q1bsp to hlbsp and the memory allocation errors.

[drm_wayne]

Any news on a new PSP build?

[Baker]

A PSP update will happen. However, at the moment it looks like a few weeks off.

I had hoped to do it sooner.

Will think about options for quick "bug fix release" fixing the 2 things I dislike the most about the prior build.

No promises. My immediate free time is rather scarce.

[drm_wayne]

How is the current status?
Maybe you can release the fixed sources so we can add it to the current ProQuake 4.70
(Mainly the random crashing and the palette bug)

Tried to fix and add stuff by myself, but it just made things even worser xD
(Textureloader from DQuake, but it ended in a mess xD)

Status: I'm working on my mod.

When my mod is done, I will want it to run on the PSP just because. So the engine will be updated.

The completion of my mod and the update to the PSP engine are rather linked. I know this isn't the answer you were hoping for, but for my personal motivation I need to have something the engine work is "for". While this answer sucks, it also sucks that I am essentially the only active person who does PSP engine stuff. Which isn't something I ever wanted to be, I was kinda hoping the large body of high quality info in this forum might induce others to the learn the deep details of the PSP engine. And for a while (2009-2010), it looked like that was working. But it isn't working, since I'm the only one. I wish there were 5 of me.

Then again, if I actually got wishes ... I'd wish for 5 Spikes, 5 MHs, 5 LordHavocs, 5 R00ks and a partridge in a pear tree.
