This thread is very easy and convient just post a question and i'll try to answer it or refer you to a place that can help you.

I would like to know how to install appliactions on my slim 3.71 m33, I have eloader but I am not sure what to do next, also half the applications don´t really say what they are or do! Please help, would be much appreciated. Thanks.

Hi. Can you be more specific. Which apps do you want to install?

I would like alarm and sleep and wake, I saw a portuguese teacher app too, but there are so many I dunno what they are or do. Is there anywhere that explains what they do?

As long as you provide with the name, we can help installing then and tell you what they do. About the alarm. Theres Sleep N Wake and psp alarm.
I believe psp alarm runs with 1.0 and 1.5 fw. You need an eboot loaded to use it.
As far as sleep n wake. It hasnt been tested all the firmwares. You can just download it and follow the instructions from the readme. All you will do is copy some files to your psp, and then youll run the app from the game menu > memory stick.

Ok I will explain what I have done so far, I downloaded some apps like I said above and put them in my GAME folder and ran them from the game menu in xmb but always got "this game could not be started" so I tried GAME150 folder but the same happened. I then found out that slims do not have 1.50 kernel and was told to use eloader which I put in a HOMEBREW folder, I did that and the alarm app worked but with no sound!!! The apps I have already downloaded have the usual two folders one having the % sign, however eloader does not recognise this folder.
I was told to find a single e.boot (WHERE & HOW?) or use pspbrew (again WHERE & HOW??!!)

I have Sleep'n'Wake PSP 1.99 MULTi8 by MK2k and pspalarm which is a single e.boot.

So thats my story pretty much and now I am stuck.
Appreciate any help I am a noob when it comes to apps!
