| Hi people, i'm just wondering what differences, if any, there are between the elf found in a retail game, and the ones that the pspsdk generates? |

Another difference is that retail games etc are not prerelocated, while PSPSDK generates elfs that are prerelocated to 0x08900000.

why are pspsdk elfs not relocatable? and out of curiosity, how would i make a common GCC compiler generate a fixed address elf given that specific address? |

PSPSDK has support for building PRXs, which are relocatable, which are equivalent to the PRXs that retail games use (including the game itself).
As for your second question, usually you pass something like "-Ttext <address in hex>" to the linker. |

| If a game is developed using PSPSDK and let's say I buy the official dev kit. Can my game be converted (I don't know if this is the right word) to the official dev kit? What I mean is this. If I develop a game using PSPSDSK and I want to publish it commercially... Can I do it? (Getting Sony's License) |

That's something that you need to discuss with Sony. As far as compatibility goes, there is no way to be 100% compatible with Sony's dev kit without having access to it, but all of the kernel libraries are mostly the same. |

mrbown,
Sorry for the confusion I was talking about compatibility.
Thanks for answering my question. |
