Trouble running homebrew

I've just downgraded to custom firmware 3.71 M33 and put a lot of home brew on my PSP, a lot of which just sat on my memory stick as corrupted data and a lot of them when booted just told me the program couldn't be started.

The ones that work are

Crash Car
Hokuto No Ken
Tetribetes
Breaker +
PSP Stack
Pipeline

The ones that don't work

Triple Triad
Puzzle Challenge
Let's Roll

I placed all the files in the Game 3.71 folder.

The ones you listed are 1.50 Kernel, you do not have access to 1.50 Kernel

Can I put the 1.50 Kernel on the PSP then??

You'll have to excuse all the questions but I am quite dense at this.

Do I need the 1.50 Kernel to run Daedalus too?

You have a slim right? No.

Look to http://dark-alex.org if you have a Phat.

No, I have a Phat.

Doesn't 3.71 M33 come with the 1.50 Kernel, it seems tp put a Game 1.50 folder on my memory stick.

Even tho there is a 1.50 GAME folder doesnt mean there is 1.50 Kernal installed. U still got to add that. Besides, i would upgrade again to 3.90 M33-3 and then add that 1.50 kernal.

Is their a tutorial that explains how to upgrade to that and add the 1.50 kernel??

Click the link for DAX's site, but I find that installing the 1.50 Kernel, and updating are basic procedures.

Heres a quick step in the right direction http://psp-hacks.com/file/4
