Help, how to launch a UMD

[valen_9]

Hello good, forgiveness for my English esque español.Estoy'm doing a program. A shell and not as a launching UMD I tried anyway, but nothing. Please give me a code to be able to launch the UMD

[ne0h]

You have to launch EBOOT.BIN.
Here is an example, here I'm using sctrlKernelLoadExecVSHWithApitype but there's some others ways...

Code: Select all

struct SceKernelLoadExecVSHParam param;
int apitype = 0;
char *program = NULL;
char *mode = NULL;

apitype = 0x120;
program = "disc0:/PSP_GAME/SYSDIR/EBOOT.BIN";
mode = "game";

memset(&param, 0, sizeof(param));
param.size = sizeof(param);
param.args = strlen(program) + 1;
param.argp = program;
param.key = mode;

sctrlKernelLoadExecVSHWithApitype(apitype, program, &param);

Thank you very much and what you provare story. Many thanks

Editorial: Do not get me compile. I have to add something in the makefile? I leave with you my main and tell me if I have something wrong Thanks

Add lpspsystemctrl_user to your makefile, and post the compilation log...

[BigProMaN]

What error did you get ?
You must link-lpspsystemctrl_user to the makefile, or lpspsystemctrl_kernel if you are in Kernel Mode.

EDIT : ne0h answered before me ^^

Have a look in the 4.01 M33, there's a SDK folder! ;)

Do not understand. You mean I need a library? Thanks for your patience and understanding

Editorial: Sorry, you already know what you mean, but they put the folder "SDK"

[NoEffex]

Download 4.01 m33. Check in the SDK folder. Open up a terminal(or window if you're using cygwin) in the SDK folder, and

cp -rf lib $PSPDEV/psp/sdk && cp -rf include $PSPDEV/psp/sdk

and overwrite all of them.

Then, if you want you can install psp-packer by going into the psp-packer directory, then the src directory, and

make && cp psp-packer $PSPDEV/bin

or on windows, just copy psp-packer.exe in the bin directory in the psp-packer directory to $PSPDEV/bin.
