If I backup my entire cygwin folder, reformat my computer then copy the cygwin folder back would cygwin work then? Or does it rely on some registry keys or other files or something that are created on instalation?
sorry, but i need to post this:
WAHOO!!!!!!! CYGWIN JUST INSTALLED DA PSPTOOLCHAIN!!!!!!
[/sorry]
now its readed and how do you write then?Zitat:
Zitat von Waterbottle
for example at that ligne stands P.H.O.T.O
and i want it I.M.A.G.E
fwrite... Theres no difference to writing normally, just move to the position in the file then write normally.Zitat:

@waterbottle thnx
they just reinstalled cygwin and its still not working:sZitat:

hallo - your english is atrocious. Bad programming comes from poor typing skills, and your demonstrating very poor typing skills..
The past tense of 'read' is 'read'... Why take the energy and time to type something that is unneeded, in this case the 'ed'... Also, i suggest you GOOGLE! next time... Most of your questions are NOT PSP specific, there fore youd find an immense amount of information on the first page of a google search.
Your problem, automake isnt installing correctly, or even at all, during installation. Choose a different, more reliable mirror. I use the ftp from redhat mirror.
Also, is piracy so important to you that you need to bookmark a torrent search engine , and blatantly show it off?
One more thing - its a called 'cropping'... Might want to look it up.
um if you looked at his screenshot, it's sort of obvious that his main language isn't english. You really shouldn't criticize other people, especially when your own post contains just as many grammatical errors.
Ok. Please, point out as many grammacical errors in my last post, to his.
Also, quit going off topic, atleast my post gave him an idea of how to fix his problem.
On Topic:
YOu may also consider using the PSPDevWin32 Intsaller if all elsefails, but it has a predefined set of libraries you can use, but its a last resort if cygwin + toolchain on your pc just dont want to mix
SG, enough criticism. I never know this side of you. Also, it's not YOu, it's You. Also, it's not grammacical error, it's grammatical. So stop criticizing, for it is not very hard to criticize you.Zitat:

super - Good point, my bad, sorry for typing too fast as my bid on ebay for a PSP just got outbid and was ending soon, so I accidentally capitalized the 'O' in 'You'. Really proves a point ;) As for grammatical and grammacical, my spelling isnt perfect, Ill admit that, but you atleast knew what I was saying, as my words were structured in a readable fashion, where as
"now its readed and how do you write then?
for example at that ligne stands P.H.O.T.O"
Is very hard, atleast for me, to make out... What is ligne (edit - just googled it and it turns out ligne is the french word for line, and is the name of a river ;) are you french hallo?) - it cant be a typo as 'g' is too far from 'n' and too far from 'i'... Im not bashing hallo for his broken english, rather hoping next time, he'll run his post through a [insert his native language] -> english converter, in hopes itll produce somewhat better results... Sorry if that came out wrong last time, or this time, its just that Ive seen many posts by hallo concerning programming, and his problem is almost always grammar (be it punctuation or spelling). So ya, sorry about earlier, little tense having to get only 8 hours asleep on the weekend :Argh:
no i am dutch ;)

is there already a way found to load usb on 2.8+??
If the normal way doesnt work, than search around for a 2.8+ app that has it. Also, to dev for 2.8+ dont you need that special SDK built for custom firmware?
I have a little question. Ive made my own particle engine, and im proud of it. Now, I want the color of each particle to intensify when overlapping another, so i was thinking something like:
PUESDO CODE:
That should make it a more intense WHITE color when 2 particles overlap, and when they dont, it should dull out to the default particle color... Im doubting itll work, so im posting here. Does anyone have a good idea as to what i could do if this method doesnt work?Code:for i=0 to max_particles {
for j=0 to max_particles {
if i != j { // so you dontcompare one particle with itself
if particle[i].x == particle[j].x and particle[i].y == particle[j].y {
particle[i].red = particle[i].green = particle[i].blue = particle[j].red = particle[j].green = particle[j].blue += 3
} else if (particle[i].red > default_color_value) {
particle[i].red = particle[i].green = particle[i].blue = particle[j].red = particle[j].green = particle[j].blue -= 3
}
}
}
}
Don't do this. It's hard to manage and slow as hell.
Just use additive blending when drawing your particles. Depending on your render API, use sceGuBlendMode(GU_ADD, GU_FIX, GU_FIX, 0xFFFFFFFF, 0xFFFFFFFF) or the GL equvialent, or in software mode when drawing, just do something like that (pseudocode):
The ADDRGB macro depends on your other macros for getting channels from a color and mixing the channels back into a color type, plus the MIN macro which returns the smaller of the two parameters (prevents color component overflow). There are tricks with LUTs to do that color addition very quickly (2 shifts, 2 and, 1 add, 1 table lookup). If you're interested LMK.Code:#define ADDRGB( C1, C2 ) RGBA( MIN(255,A(C1)+A(C2)), MIN(255,R(C1)+R(C2)), MIN(255, G(C1)+G(C2)), MIN(255,B(C1)+B(C2)) )
function putpixel( x, y, color )
{
*(FRAMEBUFFER+x+y*LINE_SIZE) = ADDRGB(*(FRAMEBUFFER+x+y*LINE_SIZE), color);
}
the last SDK sample was for 2.71Zitat:

Someone please help. I am trying to install the psptoolchain so I entered this into cygwin: ./toolchain.sh and get this error: "ERROR: Please make sure you have 'automake' installed. Any help will be appreciated, thanks.
Reinstall the toolchain (more specifically 'automake' package) from a more reliable mirror. I persobally have used the FTP redhat mirror.
Raphael - Im using Lua (only until my PSP comes in the mail) so I can't use pointers, nor the shift operator (please correect me if im wrong... seriosuly! pllllleeeasee... id love to have these). Im sure there are work arounds, but Ill just wait for my PSP to arrive and get back to using PSPGL (i might move to the GU, but OpenGL is so portable, i can codeo n PC and quite quickly port it to work on the PSP)
I used http://ps2dev.org/psp/Tools/Toolchain/, is there a better place?
There's no shift arithmetic involved in my code, unless you thought about the RGB macros. However, shifts are nothing else than multiplys or divides, depending on shift direction.
ie (x << 1 == x * 2) && (x >> 1 == x / 2). For every bit you shift, you divide/multiply by another 2, so shifting by 3 would mean mult/div by 8 (2^3).
So you can rewrite those macros into functions that do the conversion with multiplies.
For the pointer code, that was just a shortcut pseudo code for your actual PUTPIXEL/GETPIXEL function or whatever you use.Code:function RGB(r,g,b)
return r*65536 + g*256 + b;
For returning alpha value, I'd do:
Im going to give it a shot, but not using Lua, rather Visual Basic. Ill port it to work with my particle engine i have built for visual basic. I made a nice fireworks show ;) Really wow'd my teacher...Code:function RGBA(r,g,b,a) return a*(65535*256) + r*65536 + g*256 + b end
Off Topic: A college counsler lady for people to help finding colleges came up to me the other day, and she asked me some questions and whatnot, and after I said I was a freshmen and had already finished all 3 courses in just my first semester, she said that with my current knowledge, and my age -> knowledge ratio, no college wouldnt want me... I guess that means with my age, given the rest of my high school years and whatnot, I should have gained enough experience, and knowledge of hte programming concept and possibly game programming theory, I can earn a scholarship... I can say I have a fairly firm grasp on both of them, but definatly has room for improvment... Tomorow my teacher is going to sit down with me and wants me to walk him through my particle engine, since in Visual Basic, he doesnt really see any thing close to it (it's more of an application creator, what with buttons, links, horribly structured picture boxes, horrible transparency, etc.).
Raphael - Should I go talk to my counselor about the matter above? My mom says I should, that way I can get enrolled in a scholarship program, or atleast get started looking at colleges... But, I think Ive read somewhere before that you have somewhat followed this path im on, or atleast I know enough about you to respect and believe you wouldnt send me off in the wrong direction... (you wouldnt would you? I know you hate me... but i have a pretty big decisiion here :()
How do i load a jpeg image as a background?
I have installed jpeglib, Is their a certain function i need?
this has been a live for over 1 year!!
This post is not needed in this thread. Spam.Zitat:
Zitat von OWNED
I am the original creator as well ;) I like this thread as it tells me exactly WHEN i started learning C. Just one week before this thread was started ;)
Shroom - No, there is no predefined method to display jpegs using hte graphics library. Using the graphics librar,y your just loading a PNG image onto a quad as a texture, same goes forjpegs, so either transfer to using the main GU as yourgraphics API, or use Lua I guess... Or write your own data loading function for usage within the graphics library (shouldnt be too hard, i suggest this one). Also, please correct me if im wrong on graphics library and no jpeg support, since hte last time i used the graphics library was last summer. (I ditched it at the start of school, or around there, for PSPGL)
If you have been using the graphic.c/.h from Yeldarb's tutorials, then download the latest Lua Player source (0.20) and use the graphics.cpp/.h from that (there's nothing really C++ specific in it so it shouldn't be hard to convert to straight C).Zitat:
Zitat von Anti-QJ
The graphics.c/.h from Yeldarb tutorial's is from an older version of Lua Player, the current version support JPEG.
when I use I/O i normal work with arrays , but now I aint , i dont know what to do:s
source
normalCode:int getpsar(PBP_HEADER *tmp)
{
u32 filesize=0;
FILE *in;
FILE *out;
int bytesRead;
in = fopen("ms0:/eboot.pbp", "r");
printf("Extracting PSAR....!\n");
filesize = fseek(in,SEEK_END , 0);
fseek(in, SEEK_SET, tmp->psar);
out = fopen("ms0:/data.psar", "r+");
fwrite(in, ?, ?, out);
printf("Done!\n");
fclose(in);
return (filesize-tmp->psar);
}
int main(void)
{
PBP_HEADER foo;
pspDebugScreenInit();
getpsar(&foo);
return 0;
}
char wat[200];
fwrite(wat ,sizeof(wat[0]) , sizeof(wat)/sizeof(wat[0]) , dst);
but now it isnt an array , i am confused , btw it's for extracting an psar out an eboot , the functions I use are correct , they come out the devhook 2.8-3.0 installer:)
hey guys, i have a question. i just started doing C after a long time. It seems much easier than lua for me for some reason. Anyways, i finished up the first 4 tutorials in psp-programming (took around an hour). if i have a question, i will come here. this is a great thread! thanks.

Are you asking whether you should attempt to get the scholarship or should you go out and find a job?

Nothing, unless you tell us what you were expecting or what errors you got from the compiler.Zitat:
arg:. i have a problem. what is wrong with this simple code???
Oh, well, there IS something wrong:
it's KernEl, not Kernal.Code:sceKernalSleepThread();
super - You lied about being better with C than Lua... you said you have prior experience with programming in C for hte PSP, yet what your showing me here is that you have little clue... You shouldnt copy and paste ya know ;) You dont learn anything, and it gives your problems, such as what your having here. I hope you know that the debug console's font DOESNT have a transparent background, rather a black one. As for your problem, what is your problem? Compilation error? Or app error itself... I can tell you right now that the nested while loops are useless as they dont accomplish anything better than a single blitting call..
Also everyone... I have my PSP now :D It came as a 2.71 TA-082 unfortunatly, but i downgraded to 1.5 and now am living hte 3.10 OE-A world :D
Whats the command line in C++ to turn on/off USB mode for PSP?
nope. i disagree. i didn't lie about programming in C "for the psp", because i never did C "for the psp". I did do C "for the pc" though a long time ago. Also, i don't know any C classes that teach C "for the psp". Now, about me lieing about not knowing C, that is indeed false. Also, stop trying your best to condemn and criticize or getting my hopes down by using various methods. I could show and give out many times you criticize me the past couple of days (i still don't know why; maybe because someone gossiped about me?). Anyways, i understand the various problems i had before. Don't worry about the problem i had earlier because i just figured it out. If i have more problems, then i will come again.Zitat:

Its quicker to go there than to use the below copy and paste from main.c from the SDK
Spoiler for here:
an eboot is build like this
But how do you found out wich files there are inCode:typedef struct
{
char header[4];
char id[4];
u32 off_sfo;
u32 off_icon0;
u32 off_icon1;
u32 off_unknown;
u32 off_pic1;
u32 off_snd0;
u32 psp;
u32 psar;
}PBP_HEADER;
(for example an update eboot doesnt have an AT3)
I tried
if(ptm->off_snd0!=NULL)
{
}
but dindt work
Just jump to the offset, and check the file type identification cookie
checkextension=="PSAR" is false , while it has to be true:sCode:char *checkextension;
int size=0;
SceUID in;
in = sceIoOpen(wat, PSP_O_RDONLY, 0777);//open de geselecteerde file
filesize = sceIoLseek(in, 0, SEEK_END); //bereken de grootte van de eboot
printf("Opening EBOOT....size: %d kb\n" ,filesize/1024);
sceIoLseek(in, tmp->psar, SEEK_SET); //zoeken naar data.spar in eboot
sceIoRead(in, checkextension , 4);
if(checkextension=="PSAR")//als er een dat.spar is
{
when i printf it it printfs "PSAR\EBOOT , very strange:s
You can't compare strings with the == operator (at least not in C). Use strcmp.
