What are the different IRXs for?

[barf]

In my BEDATA-SYSTEM folder there is a lot of stuff:

CDVD.IRX
IOMANX.IRX
MCMAN.IRX
MCSERV.IRX
MODHSYN.IRX
MODMIDI.IRX
MODMSIN.IRX
PS2ATAD.IRX
PS2DEV9.IRX
PS2FS.IRX
PS2FTPD.IRX
PS2HDD.IRX
PS2IP.IRX
PS2IPS.IRX
PS2LINK.IRX
PS2SMAP.IRX
SIO2MAN.IRX
SJPCM.IRX
ULSND.IRX
USB_MASS.IRX
USBD.IRX
USBKB.IRX
USBTVR.IRX

Do I need all of these to run MyPS2, uLaunch, HDLoader, snesstation, pgen, xrick and ps2tris?

Not sure about MyPS2, but as for the rest, no.

USB_MASS.IRX
USBD.IRX
USBKB.IRX
Those 3 can be used by uLaunchElf, but they are not needed.

MCMAN.IRX
MCSERV.IRX
SIO2MAN.IRX
These are both in the ps2 bios by default, so unless the program is requiring some weird access, they probably arn't needed.

PS2FTPD.IRX might be from execftp, or from the uLaunchElf source, either way its for ftp, and shouldn't be needed.

As for the rest, some of them are probably from ps2link(the older versions before they builtin the irx files by default), or maybe execftp.

As far as I can tell, myPS2, HDLoader, snesstation,pgen and uLaunchElf all have their IRX files builtin, so removing the files shouldn't affect any of these(unless you are using the optional usb drivers for ulaunchelf)

Im not sure about xrick and ps2tris, to be safe cut the files and move them somewhere and see if your software still runs properly.

Well I havent deleted anything in that folder since 2003 so I have a feeling some of it is kinda stale...
