Can't start PSX eboots in IrShell

I was wondering if irshell was capable of launching PSX eboots from the applications menu. I tried launching them through the "applications" menu but it returned an error. I'm not sure why... I used Iced Tea to create these eboot.PBP(s). Is there a different method of launching these eboots using popstation? The only thing I suspected it could be were the folder names, like; Armored Core [NTSC-U]. Also, all my PSX eboots are named "eboot". none of them have unique names like games might, however applications are named "eboot" but those run fine. Im confused. Help would be very much appreciated.

Yes, IRShell can.
What's version is your psp?
If 3.90m33-x ask me a little later. If so go to my blog here and you'll find what you need.
Try using PSx2PSP, I had the same problem till I tried this.
