put ir shell on my psp but i'm not sure if it's all that compatible w/ 3.03... mostly what i want to do is play isos while listening to mp3s. is it do-able? i can't figure out how to do it.... a little help would be mucho appreciated.

first download irshell at irshell.com and then read the readme inside the extrated folder it will tell u how to install it

oh gee. download it, i didn't think of that.

if anybody else has actual help i'd still be thankfull.

I can't really help you but I might be able to save you some time.
With 3.03 OE-C I don't think it is possible (easily) to use iR Shell to listen to MP3s while playing ISOs.
I think that someone on here figured out a way of doing it but I recall that it was a bit long-winded.
The problem (I think) is that iR Shell was designed to be used with 1.50 and DevHook for playing ISOs.

So unless someone has made a plugin for iR Shell to play ISOs on custom firmware while listening to MP3s, I wouldn't try it.

that's kinda what i figured. thanks for the info.

I believe Dark Alex has a plugin for playing mp3 while playing games it comes along the 3.03 oe-c pack
