| So, what would be involved in making this happen? I know next to nothing about how an IRX file works or I'd just tackle it myself... |

You could always check out the buildsystem for ps2drv devices.

There's a rundown on the IRX file format somewhere I think in the Documents section of ps2dev.org. All it is is a relocatable ELF with an extra section that Sony uses.
If you go to freshmeat.net, there are a ton of ELF manipulation libraries and such that make it extremely easy to open an ELF file, add a few sections or scan through others, and write out the resulting ELF file. This is pretty much what you'd be doing with elf2irx, so you should check one out. I think the one I was looking at is called libelf or libmelf or something.
As we can see from the current elf2irx source, doing ELF parsing yourself is very errorprone :P.

| So, why is elf2irx needed if the compiler can spit out irx's all on it's own?? |

There are many compilers capable of generating ELFs for MIPS R3000. The only set that can generate the IRX format that the IOP expects are Binutils 2.9 and GCC 2.8.1 - these are the versions Karmix patched to generate IRXs.
elf2irx is needed for any other GCC/binutils that isn't patched. Getting the newer compilers patched is a work-in-progress.
Little known fact: If your tools can generate ECOFF, you can use those instead of IRXs on the IOP :P. You can even set your ECOFFS to load at an absolute address. |
