There has been a bit of discussion lately about what some of the various irx modules. Personally I have found this information hard to come by but it seems of few of the guys here have this knowledge. I would like to propose some kind of documentation structure on ps2dev for this information.

For each module I would like to see:
- filename ie rom0:SIO2MAN
- name
- description
- irx dependencies
- ps2sdk ee library and header

I am going to need others help but I will start this if others think it is a good idea.

I think its a great idea.

Start up an entry on the wiki (wiki.ps2dev.org) with some basic structure and get people to add what they know.

I have started, have a look at IOP IRX Modules

Are there any tools for dumping the dependencies for an irx?

I also think this is a great idea :-) I will start adding information as soon as I get back from vacation.

There is some information in the reversed IOP modules made public by [RO]man, I've mirrored them at my website, as the original website has disappeared.

As for an IRX tool there is "irxtool" by Herben available from Duke's website. I remember I had trouble using the tool, you need to set some enviroment variable to point at imports.txt file, I forgot what the variable should be called and there is no documentation, so you probably need to look in the executable to find it :-)

Get it here

You can check which files are ELF's and which are IRX's with ee-readelf.

I have an very old doc which documents the IRX format, I think it was written by Oobles or Karmix. I will try to locate it and upload as soon as I can.

It is also quite easy to find dependencies with ps2dis, using the goto function and looking for strings which match IOP module names, like "sifcmd", "sifman", "loadcore", etc. By looking in the ps2sdk IOP headers you can find much of the information need to document the IOP modules.

A nice addition to the wiki would be to add IOP module version numbers and their (numbered) exports, again information which can be obtained (partly) from the ps2sdk.

Turns out that IRX documentation I mentioned is available at ps2dev.org:

I have written a program that prints out the exported and imported functions. Function names are detected by using header files from PS2SDK.

I also called it IRX tool. ;)

Thanks Mega Man, thats what I was looking for.
I have updated the few entries in the wiki with this information.
What do people think? Is it too verbose? Is it looking good? Should I continue with the rest?

BTW This is documenting what my system is reporting. How different would it be for other versions of the console?

I dont think the information is too verbose and I think it looks fine. It would be great if you continued with the rest. Maybe also add PS2SDK IRX modules to the list?

As for different bios versions, I see a few modules on the wiki which are not included in my bios. I think there is a bios version string in one of the bios files, maybe you can add information about which bios version the module was found in.

I found this in rom0:ROMVER

0170EC20030227

Also, I was planning on doing the PS2SDK IRXs aswell. Just doing the rom ones first.

Put in all the import/export info in the wiki.

Interestingly some irxs do not have an export section at all while others have an empty export section. Some others have multiple export sections.

If I am not mistaken 0170EC20030227 means BIOS version 1.70 Europe 27/2/2003.

My pstwo has ROMVER 0200EC20040614 - BIOS version 2.0 Europe 14/6/2004

I have completed my knowledge on the rom files. Hopefully others can contribute.

Just to note that the page 'IOP IRX Modules' list all of the modules I found on my rom. However they link to an interface page. ie the rom0:TIMEMANI links to a 'timrman' page. On the interface page I have listed all the modules which implement that interface.

This works well for most modules as they only implement one interface. Some do not implement any so they link to a page with the same name as the module. Others implement many so they link to an interface page of the first interface. THREADMAN is a good example of this.

It might also be worth documenting what all of the other files in rom are.

Next I will have a go at the ps2sdk irx modules.
