[Tutorial] How to use the Screenshot Viewer

[yammata684]

The Need to Know
The basic two sentence summary how to use
Put a picture in a folder. Put the folder in ms0:/PSP/SCREENSHOT/

From here on down is optional. It's only if you want to have custom thumbnails or preview background

What the Heck Is This?

What is he talking about?!?!?!
This guide is telling you how to put pictures in the SCREENSHOT folder and how to customize how they're viewed.

Why should I even care?
Because you can customize the thumbnails of all you photo folders and add preview backgrounds

I don't want to read all this gibberish. What do I NEED TO KNOW?
Basically, take any pictures, put them in a folder, and put that folder in ms0:/PSP/SCREENSHOT/

Why should I keep on reading?
Do you want your photo folders to look like they do in the Gran Turismo folder below? If yes, continue.

There are a set of folders you can view pictures from: ms0:/PICTURE, ms0:/PSP/PHOTO/,ms0:/PSP/SCREENSHOT/, etc... This tutorial tells you how to put pictures in that folder.

Below is an example of what you can do by following this tutorial. The background isn't my wallpaper it's the preview background for the entire folder. The photo browser displays it when you hover over the folder. If you want to see for yourself check out the third attachments.



Important Points

• THE IMAGES DON'T HAVE TO BE SCREENSHOTS.
  
• The screenshot folder in which all sub-folders go is "ms0:/PSP/SCREENSHOT/".
  
• When I say "sub-folder" I am talking about the folder you put your images in.
  
• All images must be placed in a sub-folder or else they will not show.
  
• You can name your images whatever you like and put them in the sub-folder
  
• You can name your sub-folder whatever you like
  
• There is a file that goes in the sub-folders called "PSCM.DAT" - we'll talk about it later
  
• There is a file that goes in the sub-folder called "PARAM.SFO" - also, later

How to create a PARAM.SFO for Images

What the heck is a PARAM.SFO???
It's basically like an information file.

It's full of keys. Each key holds values for the name of the key. For example the PARENTAL_LEVEL key tells the PSP what the parental control level is. If the data says 7 then the level is 7.

Unlike the PARAM.SFOs for games and updates there are only 3 keys:

"PARENTAL_LEVEL" - key type: NUM
"TITLE" - key type: STR
"VERSION" - key type: NUM

Note that STR stands for string, NUM for number, and BIN for binary

The parental control and version I haven't got to work yet. The title works fine though.

1. Download, install, and run Ebootr 1.5**. It is the best for SFO editing.
   
2. Go to "File" and select "SFO Editor"
   
3. Enter the desired information to the keys mentioned earlier (view screenshot in spoiler). The values for VERSION and PARENTAL_CONTROL should just be changed to zeroes. The TITLE data is whatever you want the name of the screenshot folder to be. When entering keys, enter them in the order listed earlier.
4. Enter the key type information from earlier.
   
5. When you are done entering information click "Add". Add all 3 keys and save the SFO.
   
   

How to create a PSCM.DAT for Images

What the heck is a PSCM.DAT????
It is a PBP with the PARAM.SFO file from earlier but with images and its been put together in a specific way.

1. Rename "PSCM.DAT" "PSCM.PBP"
   
2. Use PBP Unpacker* to open the PSCM.PBP
   
3. Select everything in the lower pane and select "Extract" at the top
   
4. Where you extracted the contents there should be 3 files: ICON0.PNG, PIC1.PNG and PARAM.SFO (refer to earlier instruction on how to make).
   
5. Edit the PNG files with a photo editor. The dimensions of ICON0 are 72 X 40. PIC1 is 480 X 272 - as usual
   
6. To re-add to the PBP, open PBP Unpacker and select "New" from the top. Load all the files you edited.
   
7. Select "Save" and overwrite the original PSCM.PBP
   
8. Rename the "PSCM.PBP" "PSCM.DAT" and place in your sub-folder

If you have a properly made and put PSCM.DAT in the sub-folder then when folder is viewed in the photo browser, the name of the folder should be whatever you changed it to, a thumbnail should appear for the folder, and the background should change (Sort of like in the game and savedata browser).

Attachments

• A sample
• The PCT2.prx screenshot plugin (I don't take credit for it) modded so that it saves to a folder called "My Screenshots". It looks cool and its more convenient.
• The sample screenshots included in the first picture (Gran Turismo).
