I had a PSP with 3.40 Dark_Alex firmware installed so I can play PS1 games. I decided to try MAME emulator and found XMAME at PSP Emulation News PSP Gaming PSP Hardware PSP Homebrew PSP hacking PSP Updates Playstation Portable PSP movies PSP consoles PSP Shop Buy Preoder PSP Here (I noticed the 0.1.2 was wrong so I guess it http://psp-news.dcemu.co.uk/files/xm..._1_2_tiny.zip).

I followed the instructions and tried it out. After running XMAME I get a black screen. I reboot and I still get a black screen. Is this what a bricked PSP looks like? Or is there another way to stop this?

If my PSP is really bricked what can I do to unbrick it?
