Kazzuya's GPU

[Cyberman]

Kazz:
Well the logs are just the last 6 frames before failure...
It happens no matter what also I noticed. I think it's just before they use a special affect and it's on a DMA chain as well when things go bye bye.
The logs however are only 10K so I'm attaching them to this post (simpler)

Pete: Now I know why hardware is faster, fewer bugs in the software

Well thank goodness all the GTE codes are done by something else, it means I can just deal with the polygons alpha transparencies and textures. (yeah right JUST)

It's kind of odd that this msg board doesn't let to reply to single messages in a threaded fashion umm.

Anyhow..

Lewpy and Pete: my main idea was no caching at all indeed, cause caching is a pain ! You have to keep track of changes etc etc.
I've wrote a couple of more efficient GPU emulations before: the OGL one would only convert (4/8 to 16bits) the areas that were fetched. For that I kept a list of rects of converted and non-coverted areas. But I didnt go as far as checking for dynamic palettes 8P
The other one was similar to that, but I was using an API that assumed palette was present. So only need to convert 4bit to 8 bit. Then the API would generate a different texture for each palette ! ..That was on FF8 and worked fairly well ..especially since we got rid of the palettized fog in the 3D map 8)
In that case I also got a decent subractive rendering. Usually subtractive is used for shadows, so I'd convert the RGB texture into an alpha texture (alpha palette with Voodoo or 4444 for other cards).. something like:

alpha_texel = (R + G + B) / 3;
r_texel = g_texel = b_texel = 0;


The idea this time was more like a soft gpu using the hw acceleration at the very last stage, when the textures are all nice and ready 8)

Cyberman: got the logs, thanks. I'll see what I can understand form those. Do you think there is a chance to get a savestate as well ? 8)
I won't be checking this stuff anytime soon though. I'm leaving the country in a couple of days and I'll be busy setting things up for about a week to come. Right now I'm not on my PC..

DAMIT!.......I CAN"T UNDERSTAND ANY OF THIS ****

Yes I seriously want to thank all you plugin developers for taking emulation to a new height.Actually I live in India and almost no one here knows about emulation but since I got into it some months ago I have been trying to make as many people aware as possible.
It was really nice to read all this stuff in this thread even if i cant undertstand the technical details and terms.Just a final word for you all---"You are doing a great job,keep up the good work".

Kazz:
Yes I can but it's 1938K.
It doesn't compress more than 1% either.

Up to you what you would like to do with that, I suppose.

That's because ePSXe uses a ZIP-type algorithm on the save-states, so they are already compressed

ok..........now tell me when the new plugin is coming.......eheh.......don't get mad........just curious.....!

What new plugin?

[Adair]

*yawn*
I don't remember exactly, but someone asked Pete if he would do a DX8 plugin and Pete said it wouldn't happen anytime soon if ever and to ask you(Lewpy) about making one. Then I think someone posted that they had read something that gave them the impression that you were going to do the DX8 plugin. So there's this rumor. I would like it if the rumor were true, but I'm not getting my hopes up about it. It may have happened slightly different than that as I don't exactly remember who said what.

I think some people tend to forget that you and Pete don't spend 100% of your time coding plugins for other people's enjoyment.

Okay since U donnot understand what I mean so just leave......Im sorry..........!

[kazzuya]

HOT NEWS !!

LEWPY IS ABOUT TO RELEASE A DX8 PLUGIN !!!!!!

eheheh just kidding...


Cyberman: a savestate would allow me to play up until the game crashes and have the debugger stop exactly where it crashes.
Anyhow if 2MB is too heavy for you I understand that.. I was on a 56K modem until a week ago and I was fearing megabytes !

Kazzuya I ntoiced that your plugin runs a bit faster,but it lacks compatability.Will u be fixing it.

Kazz:
I've no problem uploading a 2Meg file I just need to know how to get it to you. That's the real problem I can't attach it like the other one

liaqatali:
I think it's a hobby of his and very I'm impressed it works so well as it does

Well I guess I know that,all I was doing was just asking...buddy

[Cyberman]

Kazz:
I sent you a personal message with the URL to grab that save state. The save state (2) is just before a level 3 attack on some critter. I know fun stuff.

liaqatali:
I suppose it's worth asking, he's a busy person it seems
