I noticed that fread function from PS2SDK isn't working properly, when I was trying to read something like that: sample code: unsigned int int_var; unsigned short int sint_var; FILE *some_fd = fopen("some_file_that_have_over_2MB","rb"); fread(&sint_var...

After few days of testing other stuff, I found what was wrong. I just used previous buffer instead of actual, so it wasn't caching or something like that - it was my mistake :). I wrote something like motion-blur, here is a screenshot: http://www.mi-ku.net/ref_images/screen_ok.jpg What my code do in...

Sorry for late, but thanks for hint emoon. I wrote "download texture" and after "screenshot" functions based on Your code and documentation distributed with linux, but using my own object-oriented library that I'm developing.

Probarly You have right. It looks like I was reading from previous cached frame buffer - not actual. This black box is frame buffer of ps2link. In first iteration theres only two triangles with big black box.

Thanks

It should look like this:

I want use frame buffer as a texture for sprite (lower left corner of screen), but I noticed funny GS behavior: http://www.mi-ku.net/ref_images/screen_01.jpg Screenshot is made in 3rd loop. It also happens when I'm doing: - local to local transmision of actual frame buffer in other place of GS memor...

I was thinking about it after my post. So I don't know actually how GS draws everything without artifacts when I'm not synchronizing it with FINISH but only with VBLANK.

My result:

PS. Check PM

Your description looks correct, the only thing I can think of with the z-buffer is that it is prohibited to set ZTE=0 in TEST, as this can cause a malfunction. I setted ZBUF.ZMSK = 1, TEST.ZTE = 1 and TEST.ZTST = ALWAYS before sending sprite and now everything is OK. You have right that setting ZTE...

I'm developing my own layer over ps2 hardware and I have problem with z-buffer. I wrote code that draw white sprite on entire screen and two triangles over this sprite. But when I swap z values of triangle 1 vertices with triangle 2 I have same effect on the screen. What I'm doing with z buffer in l...

Did you know that the syntax of your code is incorrect. - Function pointer declaration need to be done different. Star need to be moved before specifier "func". - Local variable ret is missing in enable_intc. Yes I know. I made this mistakes because i have two computers laptop and "n...

Thanks for quick response. When I said that I'm not using PS2SDK I meant using only this code what allows me to compile emtpy main (I know that is not equal to "not using" :) - sorry ). So actually I link libc from PS2SDK (printf sends text to my InLink perfectly) and libkernel - I know th...

Hello everyone. I'm new in ps2 development, but on start I'm trying to write my own library like ps2sdk - of course I stuck on begining :) Yesterday I setup my developing environment: + laptop + visual studio + my own makefile + ps2sdk linkfile + inlink + network adaptor + ps2 + ps2link - without ps...
