Writing a packer for the PSP

[Shazz]

Hello,

I spoke a little with Tyranid and Pixel about porting the great ps2packer to the PSP but it's still very fuzzy for me. And as my MStick is always full...the idea still there.

Unfortunately, it seems more complex than the (poor) view I got from writing a packer.
Basically I was thinking you need to get the ELF, save the address it should be loaded, and pack it using any slow packing/fast depacking algorithm and to run, it, depack it at the good address then jump to it...

But my vision seems to be totally wrong, so I'd like this topic to be a discussion of what to do to write a psp packer (and then makes me a little more knowledgeable)

Thanks...
