Guide: How to create PSP custom coldboots.
PSP Category: Category C

Requirements:
Category C PSP, PC on Windows, USB Cable that works with PSP.
RCO Editor
A 224x16 24-bit bitmap.
Microsoft Paint.

Instructions:
First gather all of the required items/software.
Boot your PSP into recovery mode (hold down R while turning on), select 'Advanced' and toggle Flash0 USB to 'on'.
Next use your PSP USB cable and connect it to your computer. A device should be detected. Navigate into the device and follow the
path VSH/Resource. In the Resource folder locate "opening_plugin.rco" and copy to it somewhere handy on your PC, such as
your desktop. DO NOT DELETE THE .RCO FROM YOUR PSP. IT'LL CAUSE A BRICK!
Next, use the .bmp. It says "pspupgrade.webs.com" on it, and that is the text it will show on your PSP on startup. If you want your
own personalised one, just right click on the image and select "open with Paint". Then, you can press CTRL+A then Delete, and
turn the colour on to black and fill that small box. Do not change the size. It must be that size. Then turn the colour on to white
and draw/type what you want in white. When you are done make sure you are saving it as a 24-bit bitmap.
Once you are satisfied with the picture, open up the RCO Editor application. Click 'Open RCO', then navigate to your
opening_plugin.rco extracted from the PSP flash memory. You should get lots of weird names beginning with codes like [MIG],
[VAG], and [OMG]. Don't get confused by them; they are pretty irrelevent for now. Click on '[MIG] tex_logo', and select the
'Replace' button on the right. Navigate to the .bmp. Then just leave it for a few seconds, and the editor should modify the .rco.
Then just connect your PSP back in flash0, and put it in the VSH/Resource folder, replacing the opening_plugin.rco. Make sure
you always have a backup of all of the files you modify.
If all goes well, you should start up your PSP and there is your custom coldboot.
