irshell 3.90 installing predefined homebrew

so im running irshell3.90 on 3.90m33 psp slim, and im trying to install some apps, i got mp3 lite for the HOMEBREW3x and ypaint for the HOMEBREW15 folder. and ive been trying to make them run but cant get them working, yes im a noob at this. but i got irshell and the emulators going on my own, but these apps are a head ache. idealy i would like to set them as predefined homebrew, but i cant seem to get them to start, the mp3 lite works when i set it to xmb but doesnt show up in irshells apps list when loaded. and the ypaint ive never got going. i have read the read me for irshell and followed it but theres not enough info there and the read me for the homebrews doent cover it so....... can some one help me please. how do i load these up?
