Hey everyone. I've had my PSP for quite some time, and today I found it after having lost it about a month ago. I'm not really interested in the PSP's game library anymore and I really don't care much for the system, so I think I want to "hack" it. I've never done this before and my PSP is on the latest version (5. something). I have a few questions.

1.) My laptop is broken, and the only thing I have right now is a Mac running Tiger. Will I still be able to get some sort of applications for my PSP, or do I need Windows to be able to download everything?

2.) What will I need? I only have a USB cable and a 1 gig memory stick right now.

3.) Do GBA emulators for PSP work well? I think I'll just not do this if I'm going to get a bunch of lag. I'm hoping for something similar to VBA.

Thanks in advance.
