Hey, I haven't tried this yet, but here is a link which describes how to make homebrew work on 2.71 emu w/ DevHook v0.45 - in the words of Booster himself. It appears all you need to do is change the data.psar - that becomes the PRX module thru this process. Then you put the NEW data.psar, which will be in PRX format, into DATA.PSAR in PBP Unpacker. PBP Unpacker is what you use to pack The NEW file, it appears.
You need to use PSPBrew to unpack the Main EBOOT and PBP Unpacker again to extract the contents of the "%" folder. If you've made art for your pic1 and icon0, you can keep this!
Here's the link. Good luck! I know I'm gonna need it...
