plum's Spoofer lets you spoof your PSP MAC Address (override the "MAC Address" string under [System Settings] > [System Information]) and change the date/time string format (to any format you want) on the XMB. It's a consolidation of two plugins: Davee's MAC Spoofer and Total_Noob's DayViewer.

a little off topic, but this post just reminded me of it...TN had a working dayviewer plugin that worked while in game...meaning, you still had the customized info bar when pressing the HOME button during gameplay...isnt that fuckin sweet?...he even posted proof of it working on the psp...only problem is, he never released it...why you might ask?...cuz he is a TOTAL CUNT NUGGET...damn that guy pisses me off someitmes...sorry, just wanted to vent that bit of useless info onto you people.

anyways, you can get this same effect by using the XMB Control plugin...i posted some screen shots and a brief explanation on the process i used to get it to look that way, a very long time ago...the post is called "a little psp fun" in the Site News section...but i guess if you are trying to consolidate your plugins, this would be helpful.

This crapola! never works for me. I always either get my PSP Mac address or I get [hidden]. So screw these plug ins
