I know this is an old topic, but if someone else is stuck behind a proxy, there is a solution :
this mirror of ps2dev svn support websvn:

http://psp.jim.sh/svn



so the answer is, try this:

svn co http://psp.jim.sh/svn/ps2/trunk/ps2toolchain

I tried, it works

thanks for your answers, New custom firmwares basically require a prx to be encapsulated into eboot. So the whole executable is like a library loader. While a program starts with a status setted by executing environment (or operating system...) a library does not, so a prx has _NOT_ (among other sta...

Hi, I've got a weird problem when I try to add "BUILD_PRX = 1" in my makefile. When I add this line, my program can't access file on disk, when it try to open a file, it return NULL. but without BUILD_PRX = 1, everything work fine I really don't understand why it wouldn't work this is my m...

thank you, now this is working
i'm sorry I did'nt understand your first post at first
now i can do somes tests

but i don't use any of this this is my main loop : while(running()) { sceGuStart(GU_DIRECT,list1); if(objetest.etat==0) { if(chargeobj(&objetest)==0)//load the object break;//quit &a...

thanks but i know this, I removed it but the fps is still 60 (sorry i forgot to say it in my last post)

I can't make any performance test because i can't go over 60 fps
with somes polygons : 60 fps
with 20000 polygons : 60 fps

i don"t think my fps is wrong because i can move with the same speed with somes polygons or with 20000 polygons

why ?

thanks for your answers Raphael, , sometimes 8 bit can work and it's 4 bytes aligned : 1*3+1*3+1*2 = 8 , but with somes big detailled objects, 256 isn't enough, i'll make a test but i think there is not a huge difference according to this : 8 bytes: 13.67mv/s (13.67mv/s) 10 bytes: 13.67mv/s (13.67mv...

everybody don't care ?

you should increase the "near" of guprojection, this should hepl

I searched how to get the best performances with the GU here is what I found : Textures : -use indexed textures -use swizzled textures -load textures in VRAM Vertices array : -use vertices between 8-12 bytes -EDIT : DON'T use vertex index -use stripped triangles ok, now i want to know what is the be...

oh thank you, this solve all my problems
now it's working fine (but i think i'll find another problem later)
thank you for your help

i think you"re right but i can"t find where and now i've got a very strange problem, when I allocate the memory for my texture, it change the z coordinate of the first point of my mesh i really don"t understand why i've got all theses strange problems here is the whole code : #include...

actually the light problem was in the makefile

my old makefile :
CFLAGS = -G0 -Wall

I've added "-O2" :
CFLAGS = -G0 -Wall -O2

ans now lighting is working

maybe but i haven't test 4*4 in 32 bits but i don"t have any 4*4 textures, it was only a test but now i've got another problem, with lights, i've add lights to my programm and i can't see any light i've added sceGuEnable(GU_LIGHTING); sceGuEnable(GU_LIGHT0); with the others GU setup I've add : ...

thank you for your help but i have resolved my problem using larger textures, with a 8*8 texture everything work fine seems like the minimum Texture Buffer Width is 8 because in my old texture (i've put in my first message) i have a 4*4 texture buffer and it skip lines acting like if the Texture Buf...

I want to use textures from a table with the texture, but this don"t work, somes lignes of my texture are skipped my textures is : static unsigned char __attribute__((aligned(16))) texture[]={0x00,0x00, 0xFF,0xFF, 0x00,0x0...

I've had the same problem because my texture was not alignated to 16 bytes, try this, this should work

thank you a lot
i think i understand now

but i'll continue programming later cause my psp screen is broken

but is guDrawArray faster as gumDrawarray? is there any advantages to use guDrawArray instead of gumDrawArray ?

thank you, I'll try to change things

hello everybody I can use sceGuDrawArray to draw in 2D with GU_TRANSFORM_2D but in 3D with GU_TRANSFORM_3D only sceGu m DrawArray work, but sceGuDrawArray draw nothing, why ? my program use the same GU initialisation as the sample "cube", and in the sample "cube" too, when I repl...
