you heard it here first (because i don't go nowhere else)
i have just completed my final version of my first homebrew.
it's not a game. it's a utility. what does it do? well, WHEN 2.0 is
fully exploited (meaning you can load homebrew like on 1.0/1.5)
this application will be very handy for quick psp p2p. here's what it
does:

it "creates" a jpeg image out of any file on your memory stick and
stores it in your PHOTO directory. the image it creates appears to
be a genuine 300x150 image, but it's actually 2 files (the image and the
other file). since the psp sees it as a valid jpeg you can use the new
2.0 feature to send it to another psp. neat-o, you say? for sure!

then, your pal that just received the file from you runs this same
process on his psp, only choosing to detach (or extract) the hidden
data from the image. he ends up with the file, and you both get to
be happy in your p2p ways.

NOTICE:
this doesn't and won't actually serve a purpose until 2.0 is fully exploited.
but, take the time to run it (if you have 1.5) and maybe give me some
feedback since it's my first homebrew and i'm giving it to these forums
only. or if you think the idea is stupid then don't.

2nd NOTICE:
a week ago i couldn't write any LUA at all, so there's gonna be
improvements as i learn the ins/outs of this awesome language.

finally, get it here:
