5.50 Prometheus, nice

I was trying to run "Shin Megami Tensei Persona 3 Portable (USA)" on my PSP with Custom PSP Firmware 5.50 GEN-D3, and I got this error: "This game could not be started (80020148)".  Eventually I installed "5.50_Prometheus", and now it's working OK.

On a completely related note, I found that my PSP CANNOT work with my 802.11N Asus router, and cannot work with my roommates router.  Lame.  Oh screw network then.
