I think Sony can just reverse it to know how it works, even if they dont have the source. So I think the pros have more stakes than the cons. And sincerely, I dont think our code has something Sony doesnt already know about. There are no exploit or whatsoever to be kept in secret, maybe just syscall...

Freeplay didn't contact me. I heard he just sought source from another eloader, that's all.

Anyway our eloader still needs a lot of optimizations, but at least we did it ourselves ;) And dude, you really learn a lot (and bang your head against a wall a lot xDDD)

Ok I want to release an alpha version of the Medal of Honor Heroes eloader I've been working on with ab5000 and n00b81 , but since I want it to be open source and I've been asked by some devs to keep some parts closed, like syscall estimation. I just want to make clear that we have discovered how to...

You should also check documentation about ELF format.

Yes you're totally right, it was just that.

I cannot understand why this exception is triggered: host0:/> Exception - Bus error (data) Thread ID - 0x04B5A46F Th Name - HBL EPC - 0x08E501CC Cause - 0x9000001C BadVAddr - 0x297D0504 Status - 0x00088613 zr:0x00000000 at:0xDEADBEEF v0:0x22400000 v1&a...

30+ FPS should be fine if used correctly

There's no such thing as max FPS. Although I doubt the eye will find any difference above 70 FPS. Anyway, no use having a FPS higher than screen vertical refresh rate, because the frames will not be drawn... Old films in cinema ran at 24 FPS, that's why you see some flicker in old movies. Standard P...

C# is no use on PSP. It's a .NET programming language, and as such, it needs .NET framework to be useful. So forget about C#. IMHO C/C++ is the best programming language to use with PSP, because PSPSDK is again the best SDK available to program for PSP. I would suggest you making a few simple progra...

I can help you with hooking imports, I've done it for my eloader. Let's suppose you wanna hook the import for sceIoOpen. Write a function like this one: SceUID my_sceIoOpen (const char *file, int flags, SceMode mode) { /* Your code for replacing sceIoOpen here */ } ...

Yes, as always xD

Bit 30 in address controls caching: 0 -> use cache; 1 -> do not use cache.

Just beware not using already existent NIDs, that would be a headache to debug...

Stack overflow?

@a_noob: why don't you read answers before posting?

No, of course :(

You have an example in PSPSDK, and also a recent post about this.

About what matters to me (loading code in memory and relocate) it is different. In fact, it has no similarities whatsoever with standards.

Thanks for the advice, that's what I'm doing :)

@J.F.: PRXs are not standard ELF neither they have standard MIPS relocation entries. What I'm asking is PRX specific (thus PSP specific), no other ELFs have those entries. Try a Google search about PRX and please tell me if you find something. I didn't, except YAPSPD, which is outdated and sometimes...

Try using the whole path... And why you don't just use sceKernelLoadModule()?

Of course they know the answer because otherwise they couldn't create an SDK that links PRXs :)

Maybe I'll find something in linker source...

Demo doesnt have multiplayer support where the vulnerability lays.

Thanks for sharing your solution :P

More the time passes more I believe that Sony wants that we made exploits, they give to us the 'exploitable' games ! Sony don't give you exploitable games. Games are coded by their developers, not by Sony :P But how to make an exploit ? Is there any program in the savedata ? Each vulnerability type...

Hello again! This time I'm a bit confused about some PRX sections. .rodata.sceModuleInfo Is this the correct stucture for this section? #define MAX_MODULE_NAME 0x1c /* .rodata.sceModuleInfo */ typedef struct { Elf32_Half module_attributes; Elf32_Half module_version; BYTE module_name&#91...

Use sceKernelLoadModule() for loading it and sceKernelStartModule() to start executing it.

You can check SDK example or this example from me.

Cheers

If you know nothing about programming, better start with another language than C/C++. I suggest Pascal, nice for learning structured programming. And also, start programming for PC, not PSP. It's an open platform, thus a lot of info and tutorials available, and also much more developer friendly than...

True, my bad, sorry. But maybe with an code example he/she could understand the concept better.
