December 30, 2010 // 9:36 pm - I just figured out how to create a custom PS3 boot logo for those interested by simply modifying a PlayStation 3 RAF file. Here is a sample. Replace coldboot.raf in flash with this one (or use the CFW Loader or whatever) and reboot PS3 and see your new Bootlogo!

Download: Coldboot.raf PS3 File (Sample)

Apparently this DOESN'T work for HD people yet. I don't know what happens on an HD screen, I replaced the HD file with LOL but I don't know if it will work. I'm writing a full tutorial on this, so expect it soon.

Edit: My guide is now posted below! Here's basically how I did it:

Used SimplyZip ( to decompress the RAF starting at the Zlib header (78DA) to the end of the file.

Now that you have the RAF file decompressed, it's basically a P3T (yes, Sony are that lazy) After this, you just need to run it through P3T Decompiler or whatever because you can't actually get the source files for the logo (no converter will convert them properly and I can't manually get them to show) you need to create a DDS File with these sizes:

  • Any gtf with _sd in the name - Standard Definition - 240 x 120
  • Any gtf without _sd in the name - High Definition - 700 x 350

The file sizes:

  • HD Files - 486,656 Bytes
  • SD Files - 57,088 Bytes

After making a DDS you feel is appropriate, you need to get it into the GTF format. There is a gtf/dds tool in the PS3 SDK that does this but I am not allowed to share it because I believe it is illegal. If this gets popular, a tool will almost certainly be written which will not be illegal.

After having your gtf, you'll need to create a file with the appropriate size as shown above. Go into the gtf in a hex editor and copy it. Go into the file with the size you just made and paste-write it into the file (some hex editors dont support this, its basically pasting but overwriting)

Save it. Most of your work is done. Now you must take the original gtf, copy it all in hex, then search for it in the raf. When it finds the match, just go to the beginning of the match, and paste-write. It should completely overwrite the gtf and the thing you should then see is the beginning of the next gtf. You've now written a new file into the raf.

From here, you just compress the raf with SimplyZip, then take the compressed file simplyzip gives you and insert it into the original raf. Most likely, the raf will have gained in size. This is 100% normal, as the original Sony files didn't have much in them due to the fact that is mostly empty files with a PS logo in one solid color.

Sorry if no one understood this tutorial, I wrote it in a hurry lol.

Ok, i'm a bit confused. how exactly did you get it to start at the zlib header?

Edit: Nevermind, just delete the raf header. LoL DUH!

What dds compression did you use? i think there is like 10 different dds compressions.

Awesome, thanks for the information. I have used the gtf/dds tool in the SDK to edit game textures & loading screens. Mafia 2 has .dds files that are editable as well as other games.

Ihatecompvir you might want to check out DXTbmp. It can load .dds files & save them as well. I used it to edit loading screens for Mafia 2 & Frogger Returns.

Some information on how this was accomplished would be nice. Don't be greedy!
