Ø Removal of “Install Other OS” feature

The new PS3 system will focus on delivering games and other entertainment content, and users will not be able to install other Operating Systems to the new PS3 system.

To open source community it is a sad news.

No, you needn't.

Hi, folks. Recently I found out if we update newlib-psp malloc version to the latest malloc-2.8.4, the memory fragment after a mass of allocating-and-freeing memory operations will significantly reduce. I ported it to newlib-psp-1.17.0. If anyone who suffered from the memory fragment should test thi...

please update the patch....

You can mesaure free space by allocating heap memory until malloc failed: unsigned int get_free_mem(void) { void *p[30]; unsigned int block_size = 0x04000000; unsigned int block_free = 0; int i = 0; while ((block_size >>= 1) >= 0x0400&...

Thanks, I updated the latest psplinkusb and it works fine now.

Hi, folks. When I use psp-gdb to debug my application, something weird happened: int a = 1024; int b = 768; int c = a * b; If I use gdb next instruction on "int c = a * b", it will get a very strage result: c = 64 ... The disassemble version of the code is : li $v0, 0x400 li $v1, 0x300 mul...

Sorry, I messed up pspasfparser.h, and it cannot compile at all.

Here is the patch.

I also add a reference link with its usage on how to play WMA file.

Hi, folks. I just figure out how to use libaudiocodec and libasfparser to decode wma(asf) format.

in 3.71 fw the kernel memory is forbidden from user module access. is there any way to bypass the memory access protection?

it's psp-config's fault, in the windows cmd.exe using psp-config -p will result in:

Error, path not large enough for creating the PSPSDK path

but in msys shell it seems to be OK.

Build project in the msys shell, or replace the $(shell psp-config -p) with you pspsdk location.

Do you use psp slim or 3.71 fw without 1.50 kernel support? Since slim has dropped 1.5 Kernel support, you should add BUILD_PRX=1 and PSP_FW_VERSION=371 to your makefile.

And remember you should set module attribute to 0x0000 not 0x1000, as:

Thanks a lot, it works now

int mymoduleKernelModuleCount(void) { int k1 = pspSdkSetK1(0); int ret = sceKernelModuleCount(); pspSdkSetK1(k1); return ret; } The problem remains, and here is my export.exp for the module: # Define the exports for t...

that's fixed, thx. And then, i tried to make a wrapper to let user library to use the kernel only function...: int mymoduleKernelModuleCount(void) { return sceKernelModuleCount(); } And the user client: printf("mymoduleGetVersion returns...

First, you need to use PrxDecrypt 1.7 to decrypt $ony prx files.
Second, you need a recent version of prxtool to disasm it.
The win32 version of prxtool in the download section of ps2dev won't work.
