A little precursor:
I was not the first person to successfully do
this, nor do I claim to be. I am on the other hand one of the only ones
willing to share everything I know. This is why this page is here. The more
people we have working on things like this the quicker we can reach our
goal (homebrew). Every little bit helps...right?
Summary:
As
far as I can figure out, its NOT part of the firmware...But this can be
made into a general purpose browser if you create a portal-like site to
jumps to links. When you select "Go to home page" it returns you to the
portal site (index.html). So thats an easy way out.
Yes you can
use input (we googled stuff), when you enter a textbox and press X the PSP
pops up the Keyboard API (remember there's alot of API to be taken
advantage of with the PSP). After that its as simple as anyother input on
the PSP.
The way I loaded up my own "page" is by setting up my
FreeBSD machine with some DNS entries that point ingame.scea.com and
webcluster.scea.com and all NS's for scea.com to my internal LAN machine.
So then I changed the PSP's NameServer settings to point tothe server on my
local LAN (FreeBSD machine). When the Wipeout client accesses http://ingame.scea.com/wipeout/index.html it getsmy
LOCAL file because of the DNS mapping.
It's all pretty simple after
that. I made a static page with a bunch of spring-board (or portal-like I
guess) links to access from the PSP.
Browsing is simple enough,
up and down to move from link to link. D-Pad only though. Also there is no
cursor anywhere, and no title-bars. If there is no link in the nearest
vicinity, the PSP just scrolls the page (awesome). Entering links is X,
refresh page is []. Again entering text into boxes pops up the API.
JavaScript works (Again API for Alert boxes, NEAT feature), Java is
yet to be tested. Frames don't work. Large pictures are to be tested too.
Uhm I think thats it for now. Most of HTML works (no H1's and stuff).
Background colors and pics etc work fine.
Info:
??? Once the
network connection is established and the PSP gets an IP, it sends a
request (specifically a GET forUS_holding_page.jpg from
http://ingame.scea.com/wipeout/index.html?serviceId=wipeoutpure_ingamesupport_main&hostId=ucus98612_wipeoutpure_psp_umd_1
&hostLanguage=en&pspId=&skin=Default)to
http://ingame.scea.com/wipeout/index.html using User Agent "SCEJ PSPBROWSER
0102pspNavigator", its Wipeout's webbrowser but it looks as if it's a Sony
(Sony Computer Entertainment Japan) piece of code, so this might be a
standard browser we'll be seeing. PHP rendering works great, I browsed
phpinfo(); and there's not much in there to gush about. Since there are no
links on that page, the browser lets you scroll up, down, left and right
freely.
??? As Awhite(Ioannis KarAvas)suggested, I gave Opera and
The Proxomitron a try. Set the USER AGENT and bingo,we spoof the PSP
browser:
Heh...what do we have here? Nothing but
Wipeout.
pdc^thought up of an idea to use a proxy for Wipeout's
web browsing. Now to set up a proxy and change it's requests...
What works and doesn't:
A nice chat session in #pspdev brought
about these results:
- ??? Dialog box input works (eg
google search) (fires up PSP's Keyboard API)
- JavaScript works, with Alert's and n newlines and stuff
(thanks MomDad) (again, API for MSG boxes [alerts])
- Frames
don't work.
- ??? Tags like H1/H2don't work.
To be
tested:
- ??? Straight up Java.
- Large images.
Older
stuff:
Wipeout Pure's"Download" section is a full-featured WEB
BROWSER! Here's proof:
Here's what you'd typically see if accessing that option
from the PSP (I snarfed this image while packet sniffing):
BTW, you
can't access the URL that this browser seeks directly using any kind of PC
browser.
Here's me browsing my own
stupid quickly created page:
Here's how links work (you can move left and right and
hit X to go tothe links):
Just a joke...nothing got "PWNT"
Here's how you go
back to the main page:
Returning to main index.html
Here's another link:
And here's one for the masses:
Proof by roto/mozy (Again, I'm NOT the firstperson to
do this. I am one of the first to spread the wealth though.)
Full writeup ofhow I did this is coming soon...lets just say it involved
FreeBSD, BIND, and a LOT of packet sniffing and rebuilding...those of you
that understand that already know how I did what I did. It was easy once I
figured out what the Wipeout browser was seeking
(/wipeout/US_holding_page.jpg). Basically I sniffed the packets that the
browser was seding out and receiving. I then fired up my own DNS/HTTP
servers and redirected the PSP's access to my data. I changedthe PSP's
default nameservers to the one on my LAN. Etc, etc.
Forgive me for
the sucktacular HTML and ugly pics/etc...it's 3am and I wanted to finish
this up today.
