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.
