Hey,
I made a simple game called 'The Lost Room' and I'd like to share it with ya guys. The game is smaller then 1MB and that's a good thing Here's some information about it.

It's just a DEMO. And the game is black-and-white. This was on purpose!

Requirements:
- A PSP, CFW isn't required (So, for example 3.90 is good either);
- USB Cable.

I attached a README in the download, but here's the 'how to install':
1) Run the Setup.
2) Connect your PSP with your PC, using a USB Cable.
3) Press 'Ok'.

(The files are now being copied)

4) Unplug the USB Cable and start the Internet Browser.

(You don't need internet for this)

5) Go to your Bookmarks and choose 'The Lost Room'.
