Hi, All!

I suppose my ask for advice may look a little bit strange, but anyway: did anybody hear anything about prx module with time limiting functions? e.g. my son is allowed to play only one hour a day, but he could choose when he wants to play. I couldn't find anything like this and have started to develop it by myself :) not very succefully to be honest...
I thought it could just make PSP sleep when the son played an hour a day summary (only GAME and GAME150 not in menu :)
And here is my questions:


1. is there any existing plugins with similar functionality and with sources?
2. if none, could anybody help me with at least plugin frame which can make PSP sleep?


I have had some programming expirience but it was so long time ago:)

Thank for answers!

P.S. fat PSP with cfw 3.71m33-3

I sure hope there's no such program.

If the kid has had reason to create a GAME150 folder he/she would probably
be able to defeat it unless you spend more than an hour a day writing it and set bad example.

Having said that, if you install the PSP toolchain you'll have what you need in samples directory.

Sony will have to add something like that to the firmware if they want to sell the PSP in Vietnam - one of their "Nanny Laws" says that all games, arcades, and electronic doodads must have a built in automatic way of locking the user out after a maximum of five hours.

Mmm, you may just create two plugins, one for vsh and other for game.

The one for game updates the time variable and saves it to a file at certain periods, after the hour, it shutdowns the psp or something like that.

If the bad son tries to power on the psp again, the vsh plugin would just check the file too and shut it down again.

Hum, this idea is cool, i think i could maybe add a function like this to my custom firmware extender.

It will be easy to write this plugin, the ony problem i see is the restriction could be easly prevented by removing the "game.txt" file in the seplugin folder or the plugin configuration file (this one could be writed to flash1).

The config file would have to be encrypted with the time & date or something to prevent saving it at ten minutes, and keep re using that file.
That's where it gets to spending more time on it than an hour.

What the point to encrypt a config file while the game.txt seplugin file can be deleted to disable the plugin ?
I have think about this a little and i think, for me, the best and easier thing to do is hook the usb function, if a button combination is pressed while activating usb, then load usb as normal, else return. This would secure as possible the thing (except loading the recovery menu while booting..) like an user mode access to the vsh :)

I think i will write something this week end, it's a fun project :)

I tought you wanted to only restrict games but not the access to the vsh. I am right ?

I have writed something today. There is just one plugin for game, one file on the ms with the allowed time to play in minuts. If the plugin counter reach the time in this file, the psp will reboot to the vsh. If a game (umd, homebrew...) is launched again, the psp will reboot as soon as the game start.

I'm now writing this function : if "R" button is pressed while a game is launched, a crappy menu appear and ask for a 4 digit code to disable the plugin.

The prx has to be written to flash otherwise all you have to do to defeat it is pull the memory stick and start the psp, then the prx will never load. Put the ms back in then done...

[Cpasjuste]

Not false :)
