[quote name='cochesecochese']Correct. The Windows OS and PSP Firmware are completely different architectures. There is a marginal possibility that there is some PSP specific virus out there but I haven't heard of any.[/quote]
Yea, Kind of like how its harder to get Viruses on Mac's just because Viruses are usually written for the majority of consumer computers, the PC.
