thought i'd make a new topic for this since they arent really emulators.
but this has been out for a few days,  just got to trying it now.  gotta say its pretty neat.      PSP FTP.
it lets you setup a FTP server on your PSP,  Connect to it through any FTP program and access your memory card without needing a usb wire or memory stick reader.   (of course you need one of thoes to put the ftp server on, after that however,  you dont)
so for me,   i set it up with the wireless network at work,   now i can goto work and put files and other programs/emulators onto my PSP wirelessly  
Which brings up the next point,   i dont think it will be long at all before someone makes a Web browser program.    would be nice if someone made a port of Firefox,   then i could run firefox on my PSP. hehe.
Also,   one im looking really forward to is DIVX on psp.   

  they have already released a early version of this,  it has no sound right now. but it'll be nice when they get it completly working.  Then i can put Divx files on my PSP and have them look good at a smaller size then the PSP movies.
