Where have they all gone?
Why aren't they exported any longer?
If anyone has an idea, it would be great!

| They are exported but they randomized nids, and they do it again each few new firmwares. They are not handled by nids resolver, paf is too big! |

| Moonlight, I thought that the nids where encoded, or was that the hashes? |

Could you post most of what you know for 5.00 Paf i.e. the nids?
Bad SCE!

Sure; if you know the names too.

prxtool disassemble elf or prx files. Its use to reverse enginner the file that output mips asm. |

| Im just sayin that you dont need to know the name when using prxtool. You looking for all SceGu commands, and minus what commands we have, you just need to find the names we dont have, unless you want to brute force the prx file and get the exports (that been hash with sha, but havent been encoded). |

Please donot ruin this thread again.

I am only looking for NIDs, if any one has them, kindly post it please. Thanks!

| I don't have the nids. It is a waste of time because it would make your app not work whenever 5.10 or whatever comes out. |

Got it.
There's always the option to consume more memory and use our own code instead of the ones already there :D

From which module do Games import sceGu* function from?

From none. gu library in games is a static library. |

It would be better if you just asked for particular functions rather than all the NID's. There are simply too many NID's to list them all. Which sceGu functions do you need? I'll post the 5.00 NID's for them (if that particular function is exported that is, not all of the sceGu API is exposed. Though the entire sceGu lib is embedded in paf only a handful of functions are actually exported).
Also like Moonlight said, games do not import sceGu functions from any module, they are statically linked during compilation. So the sceGu code would be inside the game binary itself (the libs are provided by Sony to the game developers to use). This is the same with the PSPSDK, the GU lib is statically linked it's not dynamically imported from any module.
@Dariusc123456:
None of your posts ever make any sense. Btw, prxtool is much more than just a disassembler.

I am particularly looking for sceGuColor, DrawArray, RotateX, RotateY, RotateZ, Finish, sceGuBlendFunc, TexFilter all sorts of interesting ones; they will save me a whole lot of user mem space.

Wouldn't it be technically possible to make an 'intelligent' NIDs resolver for sceGu functions? Since the old 3.xx NIDs are known, can't you identify some unique code in each function and programmatically look for the corresponding new NID function? Plus won't there be other clues, like the physical order of the functions in the compiled lib will be similar to the old one, even if the NIDs are different?
This process might take a few seconds to compute though, if its possible. Or you could build a mapping table for each firmware. |

You should be more specific, DrawArray, RotateX, RotateY, RotateZ, are from libGUM not libGU.
Anyway here are the NID's (for 5.00 only!!):
| Code: | From scePaf:
0xC19D3436 sceGuColor
0x6F24371F sceGuBlendFunc
0x63313176 sceGuTexFilter
0x3F946A3C sceGumDrawArray
0x702A5582 sceGumRotateX
0x7C5F6924 sceGumRotateY
0x5D92CBB8 sceGumRotateZ
|
And you'll probably want these:
| Code: | 0x742E5D6B sceGuInit
0x9EF060BF sceGuTerm
0x4CF520A3 sceGuStart
0x4170FB8F sceGuFinish
0xE252131C sceGuEnable
0xB173F74B sceGuDisable
0xB8D78044 sceGuSync
|
@Torch: I think that's how the current NID resolver works already. Does an 'intelligent' search.

Awesomatic!
Thanks.
Edit: What was the Randomizing string?
