[MaTiAz]

is there a documentation of how to use the dual boot with the modchip?

I dunno exactly what do you mean, but here's something about accessing PSP NAND when running from U.P flash.: http://forums.maxconsole.net/showpos...14&postcount=8

[hallo007]

that was what I needed;) , Thanx:)

if you call pspDebugScreenClear in a thread , will it clean the screen in another thread too?

if YES
how to you delete the text of one therad without touching the text of another thread

[slicer4ever]

anyone know know where i can learn more on how to use the psp's ir functions

[PSPJunkie_]

/usr/local/pspdev/psp/sdk/samples/ir/
and
/usr/local/pspdev/psp/sdk/include/pspsircs.h

[slicer4ever]

i did but they only go so far also not to much of a description of how it is used so i was looking for a better tut on how to use the ir commands

[PSPJunkie_]

The sdk has great documentation. You should be able to work it out with those two references.

Guys, I got a question that it a little hard for me to word, but I'll try.

If I try to make a program that gives you a list of the images on your memory stick, how would i give it a code so that it will display the .png? (I mean, no matter what the name of the png, it will load. [ I know how to load images to the screen, this is a little different ] ).

Kinda like loading a random image, how would I do that? (If I can at all)

[Insert_Witty_Name]

You worded it fine.

You need to get a list of the file names in a directory, parse these names for files that end in .png and then pick one.

Check out dirent.h, and Google for opendir, readdir, closedir etc. for how to use the functions.

I used this exact same method to get a random song from the PSP/MUSIC directory in 48 Hour Pong.

Ok. Thank you.

I don't know why but i get these errors:

main.c:844: warning: type defaults to 'int' in declaration of 'sceKernelSleepThr
ead'
main.c:844: warning: data definition has no type or storage class
main.c:845: error: syntax error before 'return'
make: *** [main.o] Error 1

I have never had this error before. What could be caused by?

[PSPJunkie_]

Code, please.

[slicer4ever]

um...it helps to see the lines

[SuperBatXS]

Wow.....this is not gonna be pretty....sure? It's pretty much my source for my biography of us presidents app that i will release this weekend (i just have to polish up my code and add mp3 player). Well, here it is:

[nataku92]

Just guessing, but I think you might have an extra closing bracket:

}
    sceKernelSleepThread();
    return 0;
}

Also, your code is ridiculously redundant. For example, this:

Spoiler for before:

           }

can be shortened to something like this:

           clearScreen(0);
           OnMain = 0;

           if (mainsetting != 44) {
               OnPicture = 1;
               picturesetting = mainsetting;
           }
           else {
               OnMenu = 1;
               menusetting = 1;
           }

There's a lot more things like this that would make you code easier to read and to maintain.

[SuperBatXS]

Thanks for the tips dude! The second code you gave me is much shorter and better, and i should have seen the pattern. Thanks. Also, by taking out the bracket, i get an error that the main function is non-static, i need that. My code compiles, and it doesn't freeze either, you can see everything loading, the home button works, and the sound is working when you move. Basically, the flipScreen is working.

The screen is the screen. If you clear it, it's cleared and stays so until you change it again. The screen doesn't care for threads or multiple processors working with it. If you consult your brain, it will give you the same answer.

I thought so , but how do you let disapere text in thread one , without touching the text in thread 2

If I understood right, just paint the text from thread 2 after clearing the screen.

[hallo007]

mm , but how does sony then creat the exit screen?

[MaTiAz]

mm , but how does sony then creat the exit screen?

Maybe it draws it's own stuff AFTER the game has drawn its own?

[BlackShark]

For a file browser, would the following check to see if a file is an mp3?

if(strcmp(".mp3", gameEntry[current_selection].name)-4)

And would this load and play that file appropriately?

MP3_Init(1);
MP3_Load(gameEntry[current_selection].name);
MP3_Play();

[hallo007]

1)if(strcmp(".mp3", gameEntry[current_selection].name) == 0)

2) dunno how you made your mp3player

the code is 100% correct , do i need to include something for classes on psp?

[Insert_Witty_Name]

Well, you need to make sure that the suffix of the file is .cpp for C++.

You'll also need to link lstdc++ in your Makefile.

oke , back to the structs , otherwhise i need to port my code to c++ , thnx anyway

dudes i was wondering if there was FireFox 2 on PSP i have searched the web and i found a prank and i was wondering if there was anyone who wanted to get into the scene this can a great idea as FireFox can change themes,has plugins(i hope it would work) and lots of updates and ThunderBird can also be a good suggestion

fixed , you need to use (SceSize args, void *argp) instead of (int argc, const char* argv[])

[slicer4ever]

how do i get the psp's mac address i know i gatta use this command:

Spoiler for command:

/**
* Get the Ethernet Address of the wlan controller
*
* @param etherAddr - pointer to a buffer of chars with at least length 7
* @return 0 on success, < 0 on error
*/
int sceWlanGetEtherAddr(char *etherAddr);

so i try and call it like:

char mac_address[7] //7 because thats what the function says to have

then i call it like:
sceWlanGetEtherAddr(mac_a ddress);

but it doesn't place anything into the mac_address as i need to get the mac address.
