First we had the 3.00 DevHook- now we have this. Why have to boot up the ol' D-H everytime you want your 3.00 VSH (Visual Shell)?
In fact, why not have your PSP boot straight to it? This can launch most homebrew, and here is a link to getting the ones it cant to load. By flashing this to your PSP you will have almost all 2.71 homebrew capabilities along with the 3.00 visualiser and camera etc.
Don't think you wont have to do anything for it though- you will have to dump 3.00 from its update eboot and then set this up using psp filer 0.5. If there's any word on a reliable installer I'll post it tonight
GET 3.00 on 2.71 HERE
