}

here is the initial code for the login page, we just need to send a http request to this page with the encrypted code. ive got the encryption done in c but i think its best to keep this part of the project closed source to stop this getting abused.

I was thinking of just building a menu system with a state manager that can easily add/remove states to the menu. The program will pretty much be just a menu with a ton of states. This can all be done in C++. I didn't think in going web-based for displaying the content for the pages. I was going to do all the content display in C++, and just do periodic requests. Whenever you go to a different page (menu state), you would have to retrieve that page's data from the server (some graphics, and other stuff). The graphical content that makes up the GUI for the menu should be stored on the PSP's memorystick locally such as the menu graphics and the menu's font. JustCC's state manager would be an awesome little tool for us to use. Although creating a state engine is a piece of cake, that's already done for us.

Now, I'm no expert on XML seeing that I'm just an HTML guy, but it looks like you have embedded C++ code into XML code? So, you will by using XML to do the network/online end of things, right? Yeah, I'm a noob to networking, but I know a little bit on the basics. I have a feeling we are on the same page, but I'm just not getting it due to my lack of knowledge on networking and using XML. Anyway, it looks good, and I like the idea of having a password to log into the user's accounts. XBox Live and the PNP from the PS3 and the XBox 360 don't appear to have those features. I will look for those features sometime on my PS3 and 360 when I get a chance.

Though about this but never took the time to implement it. Try to not make it an acronym for one specific console in case someone wants to do it for something else, such as the ipod touch or the nintendo ds

[Vincent]

The PSN was only prototype name. I was going to look into other names with the group, but I haven't been able to do hardly anything lately.

[A_Nub]

Vincent, on the C side try to code every thing in ANSI C that way it can easily be ported to any console with an internet connection and working compiler. Use BEEJ sockets for net connection. As for the GUI side that is all application independent. But make the core portable so you can also use ur comp or iPhone like nathan said to keep connected .

[Vincent]

Oh ok, I get what you guys are saying now. Yeah, the core was always going to be portable so it can be ran off a laptop and such. I would like to setup a php-browser-based monitoring system so I can check the PSN's status on my iPhone whenever I have need to (I got a new one BTW ). If I ever embrase custom firmware, it would be cool to learn more, and possibly be able to integrate teh PSN client into the firmware itself. I hear that DAX is actually setting up some sort of Network Update on the custom firmware so that it can be updated without the need for a PC. Is that true? Has Pandora's Battery become that robust to where it can all be done automatically with a click of a button? Is so, very impressive... very impressive nonetheless...

[Flatmush]

You could call it HBN, HomeBrew Network.

[Vincent]

Sounds good to me!

[BlackShark]

Looks very nice, Id love something like this, to keep me updated.
Now on making homebrew to go along side this, how would I implement my game with this system?

[A_Nub]

By writing a server and client or if you are looking for just highscores then HBN will/should provide that functionality via a .c and . H

[Vincent]

@BlackShark: Yeah, it's like A_Nub said. The client software would be a .prx file that you would link to your application via the makefile, and there's a few other things you would have to do in your source. Rest assured, we will NOT leave you in the dark at all. We'll release documentations and full examples of how to use it. The example will even be hooked up to a server. The thing is that you will have to 'register' your software with us. The reason you will have to do that is so that we can set you up a profile on the server to host whatever data records/information you want to host. I would like to keep this simple, but allow a lot of freedom with this. Think of how bungie.net works. This is kind of a generic version of it. You will be able to customize your space, and do a number of other things to make your space more personalized to the developer that our server is hosting. It'll take a little while though.

[Insert_Witty_Name]

The easiest way to implement this would be to do it natively.

I'll be commiting some code to the SDK when I get time to show how to launch the browser as a utility from within a homebrew program.

From there you can do whatever you want, login/register, view high scores etc.

The overall idea is sound in principal, but I'm interesting in hearing your views on security.

[Vincent]

Any ideas?

[BlackShark]

Very nice, I'll definitely be keeping up with this! Can be mighty useful, would this also support servers for multi player and such?.

[10YrOldH4CK3R]

If that were to happen it would be very cool tell me of anyway I can help
