Question: How to use the 1.50 kernel?
Answer: Hold the power button to turn the PSP all the way off. Now, hold the R-trigger button and power the PSP on (still holding the R-trigger). This will enter you into the "Recovery Mode", a hidden menu that only custom firmware has

. From there, go into the "Configuration" menu, and then press the "X" button on "Game folder homebrew" and in the parenthesis, it should now say, "currently: 1.50 kernel"
Question: Is there a tool to make psp themes?
Answer: Yes. There are a handful of third party programs to help you make your own themes. I can't remember any by name right now, but even Sony has made a theme program quite recently. Sorry for not being more informative, but a little searching on google or something should help you out in this department.
And hey, if you can code, I wish you all the best in any PSP-related endeavors that you may wish to embark on. Also, I responded to your thread in staxx's noobie tutorial in the tutorials section. I highly recommend that you read that.
