Support for CFW Plugins

[thiagokokada]

Support for XMB and VSH(?) plugins woudn't make sense, but support for GAME plugins would, so we can use plugins like CWCheat, translation projects like this one for Project DIVA Extended or even bypass some nasty copy protection or anything like that.

I don't really know how those work so I can't tell you yet if it will be possible. Can you point me to some source code for a GAME plugin so I can have a look?

[thiagokokada]

I didn't found anything since this is a bit old, but I asked some help from the Wololo forums (http://wololo.net/talk/viewtopic.php?f=5&t=28746), maybe they will help. And maybe this can help too: http://code.google.com/p/procfw/source/checkout. This is one CFW that supports plugins, and it's opensource.

Game plugin are just thread, they're all the same actually... VSH/Game. Think of them as dormant homebrew that's all

Any sony module is a plugin: a game plugin is just a module usually patching/hooking some stuff.

One example of plugin here: http://code.google.com/p/aemu/
This one should be directly integrated in the menu though: it would allow users to play online with adhoc games even with PSP players :)

[unknownbrackets]

Are most PSP plugins written in kernel mode? Or are some in user mode?

[devnoname120]

Half: some are user mode, some are kernel mode, some are mixing both :p
(kernel module running kernel threads and user threads).

You'll need to support both.

[StorMyu]

Iirc, all plugins are kernel, not user, I could be wrong though

Plugins that would actually patch the PSP kernel won't work in PPSSPP as their patches will not hit anything as PPSSPP is running a fake kernel outside the system emulation. But if they only call known kernel functions it should theoretically be possible to add support to run them.

[devnoname120]

There are only a few ones actually doing weak hooks (inject code into the
kernel function).
Most of them just change the imports of the modules with their own function.

[StorMyu]

I already did one like that, hooking the sceIo function to uses files on the memory stick instead of Iso/UMD (as a translation/test purpose) it's just nice to use a japanese UMD game with English :p
Need to redo it, code was pretty ugly.

The Prometheus online client also does that for 1.XX games that read adhoc
modules from the iso and then run them.

http://code.google.com/p/aemu

[cloud1250x4]

prometheus client would be bad ass ahah but it will wait till network isn't working in the emulator and this is not really important -,-'

[devnoname120]

When you say "bad", you mean "awesome"?

By the way, we don't need the network to be implemented, we can just port
the prometheus online client to cURL.

[hrydgard]

he said "bad ass" which, I gather, generally means "awesome" yes :)

What does cURL has to do with it? No reason PPSSPP couldn't have real built-in prometheus, if someone coded it.

[devnoname120]

Wait, you're right, it has clearly nothing do to with !

I was thinking to the sceHttp emulation but it has clearly nothing to do
with the adhoc functions.

Starts to work, but none of the plugins actually work since most of the things they try to do don't work correctly. JpcspTrace at least writes out the start of a log file, for example.
