yea but then how would i accept input? :Cry:

[Auraomega]

As I said, search the forums for the lastpad method, it covers everything you need here.

[hallo007]

When I call sceMp3InitResource()
it returns error: 0x8002013A

how can I fix that? what's the problem?

[Auraomega]

Check the SDK documentation, its on there what the problem is:

SCE_KERNEL_ERROR_LIBRARY_ NOT_YET_LINKED = 0x8002013a

You've not loaded the module needed to access the function.

[Xsjado7]

sceUtilityLoadModule(PSP_MODULE_AV_AVCODEC);
sceUtilityLoadModule(PSP_MODULE_AV_MP3);

[hallo007]

sceUtilityLoadModule(PSP_MODULE_AV_AVCODEC);
sceUtilityLoadModule(PSP_MODULE_AV_MP3);

Then I get SCE_KERNEL_ERROR_MODULE_M GR_BUSY (0x80020143) , module manager is busy , how do I fix that?

thnx for the link btw;)

[slasher101]

Check my post for some shortening code bits...

Search on here for lastpad methods, or you could use sceKernelDelayThread(int delay); although that method still leaves chance for an exceptionally slooooooow person to still hit the button.

My question was about a function defined already, its asking for module_start which is define in both the source and the exports already. Re-read the post to see my problem.

-Aura

yea that code is much smaller thx

There's a sample in the SDK, follow that.

[slasher101]

ive been looking at lua lately,
where EXACTLY is the IDStorage held in?
i know its in the nand "SomeWhere" but i dont know where?
and exact answer would be much apprechiated!

Ok, I'm looking for somebody who can help me over MSN with patching functions.
So, if I have questions I can ask.

[hallo007]

There's a sample in the SDK, follow that.

That sample returns me the same error code , the module manager is bussy !

[Insert_Witty_Name]

What firmware are you trying to run this on?

[hallo007]

5.00 M33

I'm using dark alex sdk for his custom firmware

sceKernelLoadModuleByID(PSP_MODULE_AV_AVCODEC , 0 , NULL);
and
sceKernelLoadModule("flash0:/kd/avcode.prx" , 0 , NULL);
return both the error code 0x80020149 , module manager is bussy

Can someone help me? I follow Tutorial 4 of PSP-Programming; image processing,
and when I compile the code it compiles with no errors, but if I want to
start the eboot on my PSP my screen stays black and my PSP crashes.

I deleted the code a while ago so i don't have it on my computer but does
somebody know where to find another sample or a tutorial about loading
a background?

[slicer4ever]

look into oslib, or tri engine, or learn the pspgu, the tutorial's on psp-programming that your referring to are fairly out of date, and the reason why it isn't working, i'd suggest would be because it didn't contain:

PSP_HEAP_SIZE_KB(20480);

however from what i understand an fully updated toolchain would be:

PSP_HEAP_SIZE_KB(-1024);

[Auraomega]

slicer is correct. Those tutorials are both old and designed for compiling elfs which have access to all the memory (check online there a good description of the difference between elfs and prxs memory allocation). When that guide was written people were still developing 1.50 applications and thus used elfs in their pbps, you can't load elfs on 2.00+ firmwares correctly, so prxs are used, but the default allocation to a prx is 32kb I believe.

where abouts is the idstorage kept in the nand??


~!SlasheR~!

[hallo007]

There's an idstorage example in the sdk

5.00 M33

I'm using dark alex sdk for his custom firmware

sceKernelLoadModuleByID(PSP_MODULE_AV_AVCODEC , 0 , NULL);
and
sceKernelLoadModule("flash0:/kd/avcode.prx" , 0 , NULL);
return both the error code 0x80020149 , module manager is bussy

?

[Insert_Witty_Name]

sceUtilityLoadModule(PSP_MODULE_AV_AVCODEC);
sceUtilityLoadModule(PSP_MODULE_AV_MP3);

If you still get the errors you're doing something weird that you're not telling us about.

[slasher101]

i know about the sample my question is not "how can i use the idstorage?"
its "WHERE is the idstorage kept?"

~!SlasheR~!

[slicer4ever]

search flash, i believe it's located at: flash0:/vsh/kd/idstorarge.prx

but i'd need to double check that to make sure and i don't have my psp on me atm

[slasher101]

no im not talking about the plugin,
the "actual" idstorage.

~!SlasheR!~

[slicer4ever]

ahh, my bad, not something i've ever looked into modifying, so i'm no help than

[slasher101]

thx 4 replying,
thats ok...

if any1 knows where it is?

!~SlasheR~!

[basfreak]

May I ask why you want to know that?

[slasher101]

does it really matter?
i want to print the ascii characters to a file for each key.

Spoiler for SECRET:

and another secret ;)

I think some people get a little worried when others mess around with IDStorage because of the irrepairable damage it can cause.

However, in reply to your question, I believe its stored in a seperate partition of the NAND, idstorage:/ but I may be thinking of the IPL, its been too long since I did any major coding on the PSP to be certain.

im not sure but doesnt dc v8 fix idstorage

[Davee]

im not sure but doesnt dc v8 fix idstorage

Not completely.

[slasher101]

Aura im not putting it into FixItPSP i just want to play with mine (ive got PLENTY on nand dumps)


Anyways do the guys talking 'bout DC8, id say it regenerates 95% of the keys, the only keys it cant fix are the magicgate ones for some reason!
