are you kidding?
EDIT:

Actually ... he's right.

[basfreak]

Between the code tags?

Edit:Damn, you know i mean the warnings, i didnt wrote the code for blit.c etc, so the warnings shouldnt be there?

[PirataNervo]

Warnings are just warnings and sometimes you can't fix the warnings.
Don't worry about fixing those right now. Once you think you can do it, try it :)

Actually, warnings should be treated as errors almost always. The code will still run, but it's still not good to have them, and it's usually quite easy to fix them.

someone knows some example of using libcurl/wifi initiating ??
i have this example psp-programming.com/animate/wlan.rar but it doesnt want to run under 3xx kernel, i have slim and cant do it on 1.5

[MiKeY188]

use this Time machine

You can test your 1.5 kernel homebrew on it ;)

[fiorello]

I don't have good pandora, anyway I don't want to use 1.5

[Davee]

Well convert it to 3xx...

[fiorello]

NO, I want libcurl samples for 3xx kernel

[FreePlay]

If you're not willing to figure out how to convert a 1.50 app to the 3.xx/4.xx kernel, you won't make it as a PSP programmer.

[Insert_Witty_Name]

NO, I want libcurl samples for 3xx kernel

There are non that I know of.

If you can't convert my code from 1.5 to 3xx+ you're gonna face worse problems down the road.

I converted, it's no problem, but error 800200D9 appears and i have no idea what to do -_-'

thats my makefile:

TARGET = wlantest
OBJS = main.o wifi.o

#To build for custom firmware:
BUILD_PRX = 1
PSP_FW_VERSION=371


INCDIR =
CFLAGS = -G0 -Wall -O0 -fno-strict-aliasing
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)
LIBDIR =
LDFLAGS =
LIBS= -lcurl -lz -lpspsdk -lpspwlan -lpspdebug

EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = PSPRPG
PSP_EBOOT_ICON = ICON0.png


PSPSDK=$(shell psp-config --pspsdk-path)

include $(PSPSDK)/lib/build.mak

You have to set the heap size.

Add "PSP_HEAP_SIZE_KB(-1024);" to your main.c file, if you have a recent toolchain, otherwise try "PSP_HEAP_SIZE_KB(20000); ".

[fiorello]

RLY ? I though to add this to code, lazy me ;p

edit: hmm still not working

[Insert_Witty_Name]

You'll need to change it from kernel mode to user mode too, as well as remove the kernel mode function calls and replace them with user mode equivalents.

I'm having trouble loading fonts with intraFont.

This seems trivial, and the supplied example compiles and works on my psp, but doing it myself (only difference is that I use c++) it fails to load (it exits the game)

The relevant code in main is just this:

int
main ()
{
	pspDebugScreenInit();
	setupCallbacks();

    if (!intraFontInit())
		sceKernelExitGame();

	// Load Fonts
    intraFont* ltn4;                                        
	ltn4 = intraFontLoad("flash0:/font/ltn4.pgf", INTRAFONT_CACHE_ASCII);

	if(!ltn4)
		sceKernelExitGame();

Start up PSPLink and debug it. Find the cause of the error. There are a few reasons your PSP will shutdown from that code (obviously). You should be able to find out yourself.

Hmm, ok, I'll try to figure out how to use a debugger on the psp (hadn't needed to use one until now), but how could anything except the file not existing (which is not the case, I checked the flash0 just incase) be the problem if almost the exact same thing works in C?

Thanks though, hopefully i can find a gdb-like debugger. (edit: wow, there exists a psp-gdb)

[basfreak]

Can some one please tell me how to patch functions?

[Davee]

lol...

How long is a piece of string?

[fiorello]

So, anybody wants to help me with libcurl ?

[basfreak]

Okay what i ment, you know hellcats wallpaper changer?
He does it too with the sceIoOpen function if it loads 01-12.bmp it loads his own from the ms.
I saw his source but it isnt clear to me tough.

Well if hooking isn't clear to you then maybe you shouldn't be doing it ;)

[Khatharr]

Bas, google for stuff about hooking on psp. It's a little complicated, so it's going to take some effort to learn.

[Moca]

Well if hooking isn't clear to you then maybe you shouldn't be doing it ;)

Nonsense. If hooking isn't clear, then he should read up on it.

Anyway, there is some nice code for hooking functions in the PSPLink source code. There's also a post on this forum by FreePlay that has some code for hooking functions.

[basfreak]

Thanks moca will take a look, any idea where the post from freeplay is?

[Khatharr]

Thank you for that response, Moca. :)

I'm also curious to find this thread. I've googled the site with a few different terms but I haven't been able to find Freeplay talking about hooking. Can you remember any other context from the discussion?

I'm not surprised.

That will give you information on the module management and more.

Might not have been a post by FreePlay. I remember nothing else from the post.

There's a lot of source code out there that should help you hook functions. The source code for Wildcard's firmware had some code for hooking functions in it. So did the source for CXMB.

Be careful with with the CXMB source. It hooks functions when they don't need to. For example they hook most of the Systemctrl functions, which, makes no sense.

cfw patch game directory stuff

Look at that post. Thats a simple hook of sceIoDopen.
